Rice University team links PM2.5 and ozone levels with cardiac arrest

Green Car Congress

A team from Rice University and the Houston Fire Department EMS has found a direct correlation between out-of-hospital cardiac arrests (OHCA) and levels of air pollution and ozone. micrograms) and ozone. For the study, OHCA events were defined as cases where EMS personnel performed chest compressions. Katherine B.

Researchers discover that a ubiquitous tire rubber–derived chemical is killing coho salmon in urban waterways: 6PPD-quinone

Green Car Congress

A team led by researchers at the University of Washington Tacoma, UW and Washington State University Puyallup have found that a highly toxic oxidation product of tire rubber particles turns streams toxic and may be responsible for the annual die-offs observed among migrating adult salmon across the US Pacific Northwest.

National Academies report finds EPA’s controlled human exposure studies of air pollution are warranted

Green Car Congress

Results from CHIE studies are used to inform the periodic review of National Ambient Air Quality Standards (NAAQS) for common pollutants, such as ozone and particulate matter (PM), and advise other policy decisions. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants.

In addition to ozone and particulate matter, the other pollutants are lead, carbon monoxide, nitrogen dioxide and sulfur dioxide. Decrease “adverse impact days,” during which people may not be able to work, go to school or otherwise be physically active because of severe breathing problems, by 19,300,000 days.
