Air Pollution from Cars, Trucks, and Buses in the US: Everyone is Exposed, But the Burdens are not Equally Shared

, Senior vehicles engineer

 Air pollution has significant impacts to public health and the cars, trucks, and buses on America’s roads contribute to this problem. While we are all exposed to this pollution, there are significant differences in the average exposure to this air pollution by different racial groups in the U.S. and exposure also varies greatly depending on where in the U.S. you live.

Dear Administrator Wheeler: This is What EPA Science Advice Looks Like

, Research Director, Center for Science and Democracy

Last Thursday and Friday, a historic meeting took place. A 20-member panel of air pollution experts met in Washington DC, despite being disbanded by EPA leaders exactly one year before. The panel’s work of advising EPA’s upcoming decision on particulate matter air pollution standards is far from over, but the meeting was a significant step in ensuring independent science can continue to inform the National Ambient Air Quality Standards, even as agency leaders sabotage the process.

Particulate matter (PM) is extremely diverse, and comes from many sources. It ranges in sizes from a few nanometers to a few microns, both of which are far smaller than anything seen by the naked eye. Source: EPA

Particulate Matter Air Pollution: Here’s Why The Facts Matter

Rick Peltier, associate professor, , UCS

Extra deaths in the US caused by particulate matter are in the range of 30,000-80,000 per year. That’s more deaths per year than from car accidents and gun deaths combined. Read more >

The EPA Cut Science Out of Air Pollution Standard-Setting. We’re Putting It Back.

, Research Director, Center for Science and Democracy

EPA leaders have now irreparably damaged the agency’s process for setting health-based air pollution standards. That’s why scientists are taking matters into their own hands. To ensure that independent science informs the particulate matter standards and beyond, the very particulate matter review panel that EPA Administrator Wheeler disbanded last year will reconvene.
