Factors influencing time-location patterns and their impact on estimates of exposure: the Multi-Ethnic Study of Atherosclerosis and Air Pollution (MESA Air) (8 page pdf, Elizabeth W. Spalt, Cynthia L. Curl, Ryan W. Allen, Martin Cohen, Kayleen Williams, Jana A. Hirsch, Sara D. Adar and Joel D. Kaufman, Journal of Exposure Science and Environmental Epidemiology, Apr. 29, 2015)
Today we review research that looked into the factors that affect long term exposure to air pollution and its impacts on cardiovascular disease (CVD) and how these compare to assumptions made in promulgating standards such as by the EPA in the USA. These factors include racial origins, time spent indoors and outdoors and age. Results indicate that Chinese spend more time indoors (3 hours more than whites for example) and that standards overestimate air pollution predictions.
