Study finds short-term exposure to air pollution may impede cognition; NSAIDs could help

Green Car Congress

Exposure to air pollution, even over the course of just a few weeks, can impede mental performance, according to a new study led by researchers at Columbia University Mailman School of Public Health. The study is among the first to explore short-term air pollution exposures and the use of NSAIDs to mitigate their effects.

Study provides more insight into air pollution mechanisms that cause cardiovascular diseases

Green Car Congress

Air pollution, and fine dust in particular, is calculated to contribute to more than four million deaths each year. While the mechanisms by which air pollutants cause cardiovascular events is undergoing continual refinement, the preponderant evidence support rapid effects of a diversity of pollutants including all particulate pollutants (e.g.

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. Peak-time risks from both pollutants rose as high as 4.6%. Relative risks were higher for men, African-Americans and people over 65. Katherine B.

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A large body of work shows that exposure to road traffic and air pollution may be a trigger of adverse cardiovascular events such as angina, myocardial infarction, and heart failure, with long-term exposure increasing the lifetime risk of death from coronary heart disease.

Study: more stringent O3 and PM2.5 air pollution standards could save thousands of lives, greatly improve public health

Green Car Congress

In “Estimated Excess Morbidity and Mortality Caused by Air Pollution above ATS Recommended Standards, 2011-2013,” published online in the August edition of Annals of the American Thoracic Society , researchers report on the annual health benefits of meeting more protective standards recommended by the ATS for O 3 and PM 2.5.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

The findings suggest that in addition to carbon dioxide, there are other compounds in need of attention and regulation. Ammonia is convected upward during events like the Asian monsoon. There are no factories or farms, and planes are thought to make up most of the pollutants in this area.
