How Do Electric Fields under High Voltage Power Lines Compare to Those Near Highways?

Comparison of charged nanoparticle concentrations near busy roads and overhead high-voltage power lines (Abstract, E.R. Jayaratne, X. Ling, L. Morawska, May 28, 2015)

Also discussed here: Roadside air can be more charged than under a high-voltage power line (Science Daily, May 28, 2015)
Today we review research from Brisbane, Australia, comparing the number of charged particles emitted by vehicles near highways to what is found under power lines. Results indicate more than twice as many charged vehicles near roads. The charges alone do not present a health hazard but the fact that the particulates are charged means that they adhere more closely to the lungs when they are breathed in – and this as earlier research has shown presents a number of health impacts which would be increased by the electrical charging.

Can Vitamin E Reduce the Impact of Particulate Matter on the Lungs?

Circulating Levels of Antioxidant Vitamins Correlate with Better Lung Function and Reduced Exposure to Ambient Pollution (Abstract, Cristina Menni, Sarah J. Metrustry, Robert P. Mohney, Sean Beevers, Ben Barratt, Tim D. Spector, Frank J. Kelly, and Ana M. Valdes, American Journal of Respiratory and Critical Care Medicine, May 15, 2015)

Also discussed here: Link between vitamin E, exposure to air pollution (ScienceDaily, May 15, 2015)

And here: Can vitamin E protect lungs from air pollution? (Indo-Asian News Service, May 15, 2015)

Today we review research into the role that vitamins plays in lessening the damage to the lungs that particulate matter plays through oxidative attacks. Results indicate that higher exposure to PM 2.5 and PM10 had lower levels of vitamin E and lower levels of lung function.

Exposure of New Born Babies to Traffic-Related Air Pollution

Perinatal Exposure to Traffic-Related Air Pollution and Atopy at 1 Year of Age in a Multi-Center Canadian Birth Cohort Study (32 pge pdf, Hind Sbihi, Ryan W. Allen, Allan Becker, Jeffrey R. Brook, Piush Mandhane, James A. Scott, Malcolm R. Sears, Padmaja Subbarao, Tim K. Takaro, Stuart E. Turvey, and Michael Brauer, Environmental Health Perspectives, Mar. 31, 2015)

Also discussed here: Exposure to air pollution in the first year of life increases risk for allergies (ScienceDaily, May 4, 2015)

Today we review research into the impact of short and longer term exposure to traffic related pollution on one year old babies. Results indicate a greater risk of allergies, especially for those who did not attend daycares with older children who seem to offer protection.

Mast cells are involved in allergy. Allergies such as pollen allergy are related to the antibody known as IgE. Like other antibodies, each IgE antibody is specific; one acts against oak pollen, another against ragweed. (Photo credit: Wikipedia)

How is Air Pollution Linked to Diabetes?

Association between Ambient Air Pollution and Diabetes Mellitus in Europe and North America: Systematic Review and Meta-Analysis (9 page pdf, Ikenna C. Eze, Lars G. Hemkens, Heiner C. Bucher, Barbara Hoffmann, Christian Schindler, Nino Künzli, Tamara Schikowski, and Nicole M. Probst-Hensch, Environmental Health Perspectives, May 1, 2015)

Today we review the results of a literature search for refereed studies or reports linking diabetes with air pollution. The search revealed over 680 reports and 13 studies that were conducted in Europe or North America- but not in developing countries. Analysis showed strong evidence linking inflammation from air pollution linked to the occurrence of Diabetes Type 2. Future studies need to take account of possible biases or unrelated causes of diabetes (such as obesity) as well as the need for this kind of research in developing countries where indoor air pollution is more likely to be a factor.

How is Europe Dealing with Air Pollution from Agriculture?

Clean Air from our Farms (4 page pdf, European Environmental Bureau Position Paper, Apr. 28, 2015)

Also discussed here : Infographic: How agricultural emissions affect our health (European Environmental Bureau, Apr. 28, 2015)

Today we review a note from the European Environmental Bureau which focuses on emissions and pollutants from agriculture which makes up 10% of all greenhouse gas emissions and 40% of the methane from the EU, and impacts both the air(acid rain), soil and human health. A National Emissions Ceilings Directive, issued in 2013, set new targets for ammonia, PM2.5 and methane among other pollutants, with a focus on livestock and manure management as well as croplands and the use of fertilizers and pesticides.

If You Live Close to Traffic, Your Brain will Shrink

Long-Term Exposure to Fine Particulate Matter, Residential Proximity to Major Roads and Measures of Brain Structure  (Abstract, Elissa H. Wilker, Sarah R. Preis, Alexa S. Beiser, Philip A. Wolf, Rhoda Au, Itai Kloog, Wenyuan Li, Joel Schwartz, Petros Koutrakis, Charles DeCarli, Sudha Seshadri, Murray A. Mittleman, Strole, American Heart Association, Apr. 23, 20-15)
Also discussed here: Long-term exposure to air pollution may pose risk to brain structure, cognitive functions (ScienceDaily, Apr. 23, 2015)
And here: Air pollution could increase risk of dementia (Laura Donnelly, The Telegraph, Apr. 23, 2015)

And here: Smog may be harming your brain (Health24, Apr. 24, 2015)

Today we review research on heath impacts on the brain from long term exposure to vehicle emissions from nearby traffic. A slight increase in PM 2.5 (by 2 μg/m3) was associated with a decrease in cerebral brain volume equivalent to an extra year of aging. This suggests the air pollution is associated with structural brain aging, even in dementia, and with a 50% greater risk of having a silent stroke which results from a blockage in the blood vessels supplying the brain.. The mechanism that links the brain to air pollution is unclear but the authors suggest that inflammation from fine particles in the lungs is likely important.

How Many Canadians Live Close to Vehicle Emissions from Major Roadways?

Development of a land-use regression model for ultrafine particles in Toronto, Canada (Abstract, Kelly Sabaliauskas , Cheol-Heon Jeong, Xiaohong Yao, Christopher Reali, Tim Sun, Greg J. Evans, Atmospheric Environment, Apr. 2015)

Also discussed here: Traffic emissions may pollute one in three Canadian homes (ScienceDaily, Apr. 21, 2015)
Today we review research into exposure to ultra-fine particles, especially those emitted by old vehicles. One third of all Canadians and half of the population of Toronto are exposed to health risks because they live within 250 m of a major roadway. 21,000 Canadians die prematurely each year because of air pollution and a large part of these deaths result from living too close to major roadways. Policy changes at the provincial and federal levels are needed to target older more polluting cars, as well as at the municipal level, to zoning plans to locate buildings and homes that house those most vulnerable from being close to traffic-related pollution – such as day cares, seniors residences, hospitals and schools.
