What are the Health Benefits of Closing Down a Freeway?

Air quality impacts of a scheduled 36-h closure of a major highway (Abstract, David C. Quiros, Qunfang Zhang, Wonsik Choi, Meilu He, Suzanne E. Paulson, Arthur M. Winer, Rui Wang, Yifang Zhua, Atmospheric Environment, Mar. 2013)

Also discussed here: Air Quality Results of a Freeway Closure (5 page pdf, Arthur Winer, Yifang Zhu, and Suzanne Paulson, ACCESS, Jun. 2014)
Today we review the quantitative improvement in air quality that results from temporary closure of a heavily used freeway in southern California. Before and after measurements of air pollutants indicate as much as a 83% reduction during the period it was closed. The authors strongly recommend that steps be taken to reduce roadside pollution from freeways in future by limiting the use of single occupancy vehicles and to convert electrically powered vehicles. Almost make one wonder who came up with the idea of freeways to start with and, more to the point, why run these “pollution sewers” through urban centres where people have to breathe the resulting pollution! Vancouver is the only major city in North America that I can think of that does NOT have a freeway running through its centre- they must have clever urban planners there!

Does Traffic Make Children Fat?

Traffic-related air pollution and obesity formation in children: a longitudinal, multilevel analysis (21 page pdf, Michael Jerrett, Rob McConnell, Jennifer Wolch, Roger Chang, Claudia Lam, Genevieve Dunton, Frank Gilliland, Fred Lurmann, Talat Islam and Kiros Berhane, Environmental Health, Jun. 9, 2014)
Today we review research into the links if any between traffic-related pollution and obesity in pre-teen children. Results indicate that children have a higher body mass index (BMI) who live in an area with higher traffic density and related pollution. Noting the direct health impacts of air pollution, this appears to be a combination of the known lower levels of physical exercise near heavy traffic, as well as such factors as drive-in fast food joints and their negative effect on healthy diets and obesity in children. Solutions include such basics as better land use planning to brings homes and jobs closer together, more use of public transit and less of private car commuting and limiting heavy traffic from the vicinity of schools and parks.

How Can We Find the Most Environmentally Sustainable Place in the World?

Construction of an environmental quality index for public health research (39 page pdf, Lynne C Messer, Jyotsna S Jagai, Kristen M Rappazzo, Danelle T Lobdell, Environmental Health, May 22, 2014)

Today we review research aimed at developing a more accurate index of environmental quality than traditional indices used to select the greenest or healthiest or highest environmental quality of a place in the world. The older indices tend to use spot observations of a single indicator to represent an area or ambient value, and they tend not to consider a combination of several variables to evaluate land, air, water, built environment and socio-demographic conditions. An example of the latter is the difference in crime rates between urban and rural areas where the latter would feel safer and have a higher environmental quality than the former, all other variables constant. On the other hand, some urban areas have a better built environment (more bike and pedestrian paths, etc) than some rural areas where highway deaths are higher.

The proposed Environmental Quality Index (or EQI) uses 22 performance indicators to estimate environmental sustainability for all the counties in the USA. The resulting indices were weighted so that there were an equal number of regions at the low end as well as at the high end of the index scale. As the authors note, the EQI represents only the outdoor environment and indoor conditions may, on occasion, be more important from a health point of view or need to estimated from a different set of variables.

And here: Environmental group proposes warning labels on gas nozzles (Toronto Star, May 23, 2014)

Today we review a submission to Toronto City Council calling for a bylaw that would require gas stations to apply a climate change warning sign to their pumps. This follows the same rationale and municipal authority used for bylaws that ban idling which also was aimed at reducing needless vehicle emissions, as well as the health justifications used by municipalities for banning smoking inside restaurants and bars and city buildings, as well as near their entrances. Just as the tobacco companies fought smoking bans and health warning signs on cigarette packages, so the oil industry is likely to fight this proposal- with hopefully the same result. A similar bylaw is being proposed in West Vancouver and Hudson. Why not in other cities where vehicle emissions are a major greenhouse gas source and health risk?

Use of Air Conditioners Increases Nighttime Temperatures, Escalates Demand for Air Conditioning – Experts advise turning ‘wasted heat’ into ‘useful energy’ (Newswise, May 16, 2014)

Today we review research carried out in Phoenix, Arizona to assess the impact of air conditioning on the urban heat island. Results indicate that air conditioning increases the mean air temperature by 1 deg C and that air conditioning consumes more than 50% of electricity used during extreme heat events. Instead of simply exhausting this heat into the atmosphere, the report recommends that it could be used for useful activities inside the house such as water heaters which could result in savings of at least 1200 MWh per day for the city. Continued climate warming will make this an even bigger issue affecting not only the formation of smog from ozone and excessive heat. Redirecting the exhaust heat offers the possibility of reducing electrical usage which itself is produced by the burning of carbon fuels which accelerate climate warming.

Is Windshield Washer Spray a Health Hazard?

Windshield Washer Fluid a Source of Legionnaires (ASMevents, American Society for Microbiology, May 19, 2014)
Also discussed here: Windshield washer fluid a source of Legionnaires: Found in most school buses (ScienceDaily, May 18, 2014)

Today we review research by Otto Schwake who established a link between windshield washer fluid and Legionnaires’ disease, a severe form of pneumonia. The link is a bacteria, Legionella, found in the fluid which is transmitted to humans in the mist that is formed when sprayed on the windshield and then inhaled. The bacteria can also cause Pontiac fever, a milder illness resembling the flu. More bacteria were found in summer than in winter and in 75% of the washer fluid samples taken from school buses in Arizona. Although most people exposed to this threat do not become sick, seniors and smokers are at most risk. As much as 20% of those affected by Legionnaires’ disease in the UK, outside of those in hospitals, was found to be associated with automobile windshield washer fluid. One more reason to reduce the number of cars on the road and the pollution they cause.

And here: How Does Outside Air Pollution Affect Indoor Air Pollution?

Today we review research into the link between roadside noise and heart disease, noting that earlier studies had shown a link between heart disease and traffic-related air pollution. Results indicate that exposure to noise at different frequencies is strongly linked to hypertension, especially exposure to noise from motorcycles. These results provide further justification for municipal zoning which keeps heavy traffic at a safe distance from residences, especially for old age nursing homes where heart disease is frequently the cause for death. Steps have been taken in Halton Region in southwestern Ontario, Canada to do precisely that where major roads would be less than 30 m away from housing developments (or highways within 150 m).

Today we review a report from the World Health Organization that presents the state of air quality in 1600 cities world-wide in an Excel data base that is easy to manipulate. Only 1/8th of the cities surveyed meet WHO guidelines for fine particulate matter (PM). Those that do better (examples Bogota, Colombia and Copenhagen, Denmark) do it by actively promoting cycling and walking. 88% of the 3.7 million premature deaths/ year because of air pollution occur in low and middle income countries and most of these are in the Western Pacific and Southeast Asia. 7 out of the 10 most polluted cities with the highest levels of particulate matter (PM10) are in Pakistan (Pakistan: Peshwar, Rawalindi and Karachi) or India (Gwalior, Ahvaz, Raipur and Delhi) while all 10 of the least polluted cities are in the USA (mainly in the southwest). Even in regions such as Europe, where WHO guidelines are generally met, lives are shortened by 8.6 months because of exposure to PM.

How does the Public View the Cost of Air Pollution and Noise?

Multi-country willingness to pay study on road-traffic environmental health effects: are people willing and able to provide a number? (24 page pdf, Tifanny Istamto, Danny Houthuijs and Erik Lebret, Environmental Health,May 9.2014)
Today we review research aimed at finding ouit how to ask the publics in four European countries what cost the see in the impacts of air pollution and noise, recognizing that these two environmental conditions impact the public in different ways and so must be assessed differently. One of the challenges in designing questionnaires is to identify and if possible reduce the number of don’t know (DK) and protest vote (PV) answers through the use of factual choices and scenarios in a process meant to capture what the public is willing to pay (WTP) to reduce the impacts- and then assess if the proportion of DK’s varies by country or socio-economic status etc. About 1/3 of the PVs thought that the polluter or the government should pay for reducing air pollution or noise.

Has Health Impacts fromToronto’s Traffic-Related Air Pollution Become Worse?

Path to Healthier Air: Toronto Air Pollution Burden of Illness Update(15 page pdf, Dr. David McKeown, Medical Officer of Health, City of Toronto Board of Health, Apr. 11, 2014)
Today we review an updated report from Toronto’s Medical Officer of Health on the health impacts from air pollution in Canada’s largest city (and the 4th largest in the USA and Canada). The good news is that the number of premature deaths have decreased by 23% and hospitalizations by 41% over the last decade showing the benefits of a number of steps taken to reduce vehicle emissions including a Bike Plan, A Green Fleet Plan and the ChemTrac program to follow emissions from businesses. A major improvement also resulted from the provincial order to shut down all coal-fired utilities by 2014.

The bad news is that traffic related pollution contributes to 20% of these deaths and if one considers only pollution originating from within city boundaries, 42% of deaths. One culprit is the role of heavy, diesel-powered vehicles which make up only 1.5% of vehicles but are responsible for 80% of PM 2.5 and over half of NOx emissions. One recommendation is to develop an urban freight strategy which would shift truck delivery away from rush hours and improve efficiency. Another is to add to the present network of four surface air monitors in order to pin point sources of air pollution which also include toxic gases from businesses in the city.

Included in a number of suggestions are the collection of the costs to maintain infrastructure needed for cars and the full costs for health costs caused by cars and the costs for building walkable cities and alternative modes of transportation Revenue for these improvements would come from gas taxes and tolls on roads, bridges and freeways. . Signficant advances in GPS technology and computer communications make the collection of these funds much more feasible, effective and more convenient than ever before, reducing the overhead from over 50% to less than 5%.

Today we review a study that had surprising results for older people in reasonably good health who live near traffic and air pollution in a large American city (Boston). Despite much environmental health research that this exposure causes neurological and cardiovascular diseases, there was no evidence from this study that air pollution on a short or long term bases causes depression. By contrast, it is worth noting that those most likely to suffer depression and living near traffic were younger females.

More than 60% of deaths from indoor air pollution are attributed to strokes and Ischaemic heart disease with most of the remaining deaths (34%) from COPD and acute lower respiratory disease. The smallest cause (6%), unlike tobacco smoking is lung cancer. By contrast, 80% of deaths from outdoor air pollution were Ischaemic heart disease and from strokes.

How Dangerous is it to Live Near a Wind Turbine?

Measuring electromagnetic fields (EMF) around wind turbines in Canada: is there a human health concern?(8 page pdf, Lindsay C McCallum, Melissa L Whitfield Aslund, Loren D Knopper, Glenn M Ferguson and Christopher A Ollson, Environmental Health, Feb. 15 ,2014)

Also discussed here: Electromagnetic fields and public health – Exposure to extremely low frequency fields(Backgrounder, World Health Organization, June 2007)
Today we review the first objective research into health hazards near wind turbines n Canada, based on extensive measurements of electromagnetic fields (EMF) near a wind farm in southwestern Ontario. Despite popular fears about the potential dangers, results indicate that the EMF near a wind turbine (3-4 mG) is much less than from a microwave oven (300 mG) or a electric shaver (600mG) and therefore does not constitute a significant health threat which is backed up by statements form the World Health Organization and Health Canada. Even the fields below high voltage (500 kV) power lines, another target of public health concerns, are small (16-46 mG) by comparison. This finding is important in dismissing arguments against windpower which could be a major replacement for carbon-powered electricity sources which play a large role in high air pollution levels.

Facts show that inattentive drivers and speeders are the biggest causes of crashes that kill pedestrians and older pedestrians in particular. Such measures as red light cameras, speed bumps and just keeping track of and controlling drivers in these “accidents” have brought traffic fatalities down putting New York City as the safest city in the USA (with 3.5 fatalities per 100,000 pop., compared to Chicago at 6 and Atlanta at 11) and Stockholm, Sweden (with 1.2 fatalities)  as the safest in the world- possible only with application of a wide range of efforts. Only by making streets safe for walking (and cycling) will cities shift from ones congested with traffic and air pollution to healthier ones.

Today we review research into the links between traffic exhaust and the health of children. Results indicate that three times as many obese children have asthma as non-obese children. Further that this type of pollution also has a negative effect on birth weights. Explanations have to do with the greater time spent indoors by overweight children, exposing them to more polycyclic aromatic hydrocarbons (PAH) and the fact that overweight children breath at a greater rate than non obese ones and thus have greater exposure to pollution.

Measuring psychological resilience to disasters: are evidence-based indicators – an achievable goal?  (20 page pdf, Jose Manuel Rodriguez-Llanes, Femke Vos, Debarati Guha-Sapir, Environmental Health , Dec. 20, 2013)

Today we review the ways that resilience can be measured and in particular, psychological resilience, based on a literature review of this factor in various scenarios and disasters. Unlike many climate impact studies this research looks at human behavior and how humans react to events that present challenges. Results indicate not surprisingly that social support increased resilience, in general, while women showed a larger risk of lower psychological resilience following a disaster. These findings would be important in disaster planning especially with the higher risk of larger and larger disasters expected with the greater variability of wind, temperature and precipitation extremes from climate change.

This is not only a shock that could lead to depression or worse if unprepared but statistics show that more and more of those over 65 are driving, especially females. The trend toward poor urban design in many cities that encourages sprawl and a dependence on having a car does not help.  Public transit is not a viable option for many seniors. Solutions include involving seniors in training and developing social outlets in the community to seek out ways to lead happy lives without dependence on a car.

Is Denying Climate Change Like Suppressing Health Risks?

Is Learning about Climate Change like Having a Colonoscopy? (5 page pdf, Richard C. J. Somerville, Earth’s Future, Dec. 16, 2013)

Readers of this blog know that it focuses on the links between urban pollution and health. Today we review a short article that addresses the challenge of communicating the facts of climate change and why so many people seem to want to avoid knowing that or even deny that it exists.  The article observed that the same reaction is found when some people are faced with the hard realities of medical disease, especially ones that end in death such as heart attacks and cancer. Further, a poll revealed that over half (55%) of those responding did not want to know about their risk to disease because of their fear of knowing the answer, a phenomenon called “health information avoidance”. But most of those who did want to know the risks (82%) also wanted to know the options available to deal with the disease. Turning to communicating climate change, the author reasoned that a little priming of the pump by providing more about policy options could produce more understanding and support for those policies and less climate change information avoidance and denial. Let’s hope.

Today we review a report from MIT which examines the state of urban health in the eight largest cities in the USA and explores ways to improve it  socially,  economically and environmentally, while testing the validity of several widely held assumptions. One belief, for example is the greater urban density can be linked to improved urban health while data suggest the opposite when it comes to water quality and biodiversity in cities. Adding more sidewalks to encourage more exercise from walking also puts people at risk if the sidewalks are close to vehicle emissions from heavy traffic. Measures of urban health for planners are different and sometimes incompatible with those used by public health specialists. The report contains rich, informative and differing assessments of each of the cities considered.

How Does Bad Air Affect the Economy?

Ripple effects of air pollution felt in many sectors (China Daily, Dec. 10, 2013)

And here : Commissioner hints at new EU air quality measures (Air Quality news, Dec. 11, 2013)

Today we review a news story which brought up an interesting aspect of heavy air pollution and the reaction by the people it affects – mainly the older and younger generations. In this case, it is an example from large polluted Chinese cities, but the levels observed are not that much different from those observed in the downtowns of many large congested western cities, so the same reaction and impacts can be expected. This includes the travel industry where those with the time and money to travel deliberately – the baby boomers over 65 – chose destinations with cleaner air and avoid those with polluted air. Schools are closed in China for the same reason that those in urban areas of  the USA and Canada which are within 200 m of heavy traffic should be closed.

While the Chinese government seeks to improve its air quality (by 20% in 4 years!), and action is being taken to strengthen EU air quality guidelines, their counterparts in Canada and USA focus only on ambient air standards while roadside air quality becomes worse as cities attract more and more polluting vehicles and traffic congestion. Only one jurisdiction in Canada (Halton Region in southwestern Ontario) has taken steps to monitor roadside emission and keep heavy traffic away from residences because of vehicle pollution and the health threat this represents. Meanwhile, more people die from air pollution than from obesity and traffic accidents combined (at last count, 21,000 premature deaths each year in Canada).

Today we review research into the health impact of long term (10 years) exposure to particulate matter and how this affects the thickening of arterial walls [intima-medial thickness]and heart disease through  atherosclerosis. Results indicate that an increase of PM 2.5 mg/m3 is associated with a 2%  relative increase in strokes and is evident at the neighbourhood level. This is significant because it expands the impact of PM from the known impact of short term exposure to long term. It also suggests that neighbourhoods located near higher levels of PM (such as proximity to vehicle emissions from traffic) would have higher mortality. Studies (such as from the City of  Ottawa) show that many urban areas have more than 50% of vulnerable populations living within 50 m of busy roads and are at risk.pm and strokesproximity to roads ottawa

What Do Crematoriums Contribute to Urban Air Pollution?

Toxic Emissions from Crematories: A Review(7 page pdf, Montse Mari, José L. Domingo, Environment International, Oct. 12, 2009)

Also discussed here: Incineration – EMEP/EEA Emission Inventory Guidebook(13 page pdf, Marc Deslauriers, David R. Niemi and Mike Woodfield, 2009)

Today we review the literature on emissions from incineration  of human bodies which is the way almost all bodies are disposed of in Japan and China and have increased to around 37% in the USA and Europe today and increasing about 10% per decade. Very few analyses of emissions from crematoriums are available but there are concerns about the amount of mercury from tooth fillings that end up in the air. The paper concludes that unless  mercury emissions from crematories are properly controlled, these facilities -which number over 1,000 in Europe alone – could become an important source of air pollution.

How can Mobile Phones be used to Estimate Air Pollution Exposure?

Mobile phone tracking: in support of modelling traffic-related air pollution contribution to individual exposure and its implications for public health impact assessment(26 page pdf, Hai-Ying Liu , Erik Skjetne, Mike Kobernus, Environmental Health, Nov. 4, 2013)

Today we review a paper that explores an approach that uses personal mobile phones equipped with GPS tracking ability to estimate the exposure of a group of individuals to air pollution and make these estimates available in real-time at low cost. Such a method could be applied in developing countries where expensive monitoring equipment is often unaffordable. The potential of gathering information such as this from a wide segment of society also opens up very large opportunities for progress in public health by collective tracking of large numbers of people.

Is There a Need for Standards for Brief Peaks of Air Pollutants?

Peak event analysis: a novel empirical method for the evaluation of elevated particulate events(12 page pdf, Aaron Orkin, Pamela Leece, Thomas Piggott, Paul Burt, Ray Copes, Environmental Health, Nov. 1, 2013)

Today we review research into the occurrence of brief peaks of suspended particles (or dust), how often they occur (in a rural area of southern Ontario) and if the results point to a need for standards for periods of less than an hour- the shortest time period currently used in Canada and many other countries. The resulting analysis showed that peak values of PM10  twenty to one hundred times greater than values averaged over an hour which were within the current standards. Although the aim of the research was to examine single events with high associated levels of pollution, one cannot help but wonder what the health impacts would be for people exposed to repeated doses of high pollution for shorter periods than are covered by existing standards, such as proximity to roadside emissions at rush hour each day. If there is a definable health impact, that would both call for standards for shorter periods- say 10 minutes or one minute- and might explain the degree of mortality associated with traffic (which has been estimated as about 1/3 of all deaths from outdoor air pollution in a study conducted by the City of Toronto Medical Officer of Health).

This is part of a larger research project aimed at assessing the health risks of roadside air pollution in Canada’s largest city where more than 2,000 people die prematurely each year according to the Illness Costs of Air Pollution (ICAP) model developed by the Ontario Medical Association and widely recognized by established authorities (such as the Auditor General of Canada and the Commissioner for the Environment  for Ontario). The sensors provide a required precision of 5 to 15 ppb for O3 and NO2, 20 microgm/m3 for PM 2.5 and the entire cost of the unit is expected to be under $300.

At the same time, however, double digit GNP industrial growth over the last few decades has produced an even greater overall increase in  emissions and a deadly level of pollution in cities located near industrial centres, such as Harbin and Beijing. A modest carbon tax ($10/ton) could prevent close to 90,000 premature deaths each year and bring in much needed revenue to further accelerate the use of non-polluting energy sources.

Today we review research based on ground air quality monitors and remote satellite air quality imagery that points to the elevated levels of carcinogenic air pollution, downwind of oil sands processing plants in western Canada. This moves the debate about the Alberta oil sands from one about greenhouse gas emissions and climate change to one about direct health impacts, such as leukemia, for those who live downwind of these utilities.  The findings indicated levels of volatile pollutants such as benzene higher than found in large polluted cities elsewhere in the world. It also underlined the value of taking actual measurements of air quality near industrial plants rather than depending on assumptions from models and stack emissions, as is the case with many urban incinerators, such as the Plasco municipal waste disposal plant near Ottawa.

Today we review research into the public health risk posed to Canadians (and citizens of other countries) from traffic –related air pollution, especially to the third of its population (10M) that lives within the length of a football field (100 m) of major roads with heavy traffic. Solutions include, first and foremost, reducing vehicle emissions by reducing traffic congestion, keeping high emission vehicles, such as trucks and buses, away from schools, day-cares and retirement homes though better zoning to reduce sprawl, as defined in official municipal plans, and encouraging alternate commuting modes with urban congestion charge zones among other options.

Today we review a report from the UK which looked at the presence of Legionella in composts both store-bought and home-made. Almost 60% of the composts contained Legionella which can cause human disease. The good news is that  infection from this is rare, especially if proper hygiene is followed – and it is recommended that compost packaging carry public health warnings to this effect.

Also discussed here:Next Generation Suburbs(19 page pdf, David McKeown, Medical Officer of Health, The Chief Planner Roundtable, Toronto, Apr. 2, 2013)

Today we examine the future and viability of suburban areas that have grown in the last era of cheap oil and uncontrolled sprawl that has afflicted many cities since the end of World War 2. This period now seems to be coming to an end as the boomer generation which fed suburban growth wants to downsize and move to a residence closer to the urban core where a more attractive life style and conveniences awaits them. Property taxes in the suburbs which have been low compared to urban rates now will rise because of costs to renew the infrastructure are passed on to suburban residents. At the same time, the flood of commuters continue to bring traffic congestion and unhealthy air pollution with the vehicles to the urban core. A key aspect is the need to plan for transportation modes that encourage exercise (walking and cycling) to curb the obesity that comes from dependence on driving and the need for more greenspace in the urban cores.

And here: Population Aging and Economic Growth in Asia(30 page pdf, David E. Bloom, David Canning, and Jocelyn E. Finlay, the National Bureau of Economic Research, University of Chicago Press, Aug. 2010)

Today we review recent population analyses which focus on the combined effect of the aging society with lower fertility and increased migration (in some countries) and the trends expected through this century. The reason this topic was examined is the increase in vulnerability to exposure to air pollution and the health impacts, seen in many studies of the elderly. While pointing out that consumption (and therefore pollution) increases from childhood through to senior years, from an economic point of view, aging by itself is not a negative aspect provided those in their working years plan for their retirement income – which given the recent tendency of the state to retreat from this responsibility would or should encourage more self reliance. That in turn could translate into a greater ability to maintain quality of life and of the environment.
