A research team led by Fabio Caiazzo of MIT recently quantified the impact of air pollution and premature death in the United States for the year 2005. They found that road-related particulate matter was responsible for about 19% more deaths, nationwide, than car crashes. Read all about it.
Our own Wig Zamore adds:
Unfortunately, the air pollution death valuation is WAY LOW because only traffic contributions to regional, as opposed to local, pollution are counted. Experienced and well regarded southern California environmental health scientists will soon publish a heath impact assessment study suggesting that in 2035 local traffic related air pollution in southern California will be responsible for as many deaths per year as total regional fine particle pollution. Given how much smaller the near roadway population is this is a stunning outcome!
This suggests that the total local and regional traffic pollution deaths are about three times what this article suggests. In general the colder a region is, the higher the ratio of local traffic emissions effects to regional traffic emission effects. Cold weather drives higher local primary pollution concentrations and gradients, warm weather drives higher regional secondary pollution concentrations.

Two recent independent studies now suggest that simply living near major roadways and breathing harmful emissions from motor vehicles might be an even greater threat to U.S. health than accidents are. Read more.

Science Daily: "Near-Roadway Air Pollution a Major Contributor to Asthma in Los Angeles County, Research Finds"
"Our findings suggest that there are large and previously unappreciated public health consequences of air pollution in Los Angeles County and probably other metropolitan areas with large numbers of children living near major traffic corridors," said Rob McConnell, professor of preventive medicine, Keck School of Medicine of USC.

Tufts Medicine Magazine: "Big Road Blues: Living Near a Highway Can Be Bad for Your Health in a Million Small Ways" (PDF)
"The goal of the study, expected to wrap up a year from now, is to understand how vehicular pollution affects the health of people living close to a highway."
"'When it comes to air pollution, the main thing that really affects people is particulates - not gases,' says Doug Brugge, the study's principal investigator and a professor of public health and community medicine at Tufts. 'The Environmental Protection Agency estimates that they cause 80,000 or 100,000 deaths a year in the United States, and maybe four million or more worldwide.'"

Boston Globe: "Air pollution tied to stroke risk"
Car exhaust and other air pollution, even at levels considered safe by federal regulations, may substantially increase the risk of a stroke, a research team from Beth Israel Deaconess Medical Center reported yesterday.

An important new report from American Lung Association, Clean Air Task Force and Earthjustice (originally the Sierra Club legal arm) has just been released: "SICK OF SOOT - How the EPA can save lives by cleaning up fine particle pollution." This summarizes a large new study which calculates the health effects of fine particles in the US.

BBC News: "Car fumes 'raise heart attack risk for six-hour window'"
Prof Jeremy Pearson, associate medical director at the British Heart Foundation, which co-funded the study, said: "This large-scale study shows conclusively that your risk of having a heart attack goes up temporarily, for around six hours, after breathing in higher levels of vehicle exhaust."

"Wake up to the most dangerous air pollution: Fine particulate matter kills thousands in N.Y.C., L.A."
Co-authored by STEP's Wig Zamore
"Fine particulate matter is especially insidious because it is virtually invisible, odorless and tasteless. All of us are exposed, but few are aware of it. Despite the substantial impact on our health, it is not well-known to the public compared with many environmental exposures that pose far smaller health risks, such as electromagnetic fields from cell phones or the hazardous chemicals at waste sites. In terms of health risks and number of people affected, particulate matter should rank in importance with other public health concerns such as smoking and secondhand smoke exposure and obesity trends."

Somerville Journal: "Somerville receives federal grant to study air pollution near I-93 homes"
"STEP is very enthusiastic to be a partner for this study," said STEP President Ellin Reisner. "For the past year, we have worked as a community partner with Tufts University studying UFP exposure of residents in East Somerville living near I-93. This study provides our community with a critically important opportunity to identify ways to effectively reduce indoor UFP exposure which can have serious cardiovascular health consequences."
