HEI study in Europe finds evidence of health effects at lower levels of air pollution

Green Car Congress

In the report, the investigators describe the development of new exposure models for all of Europe for four pollutants: fine particulate matter (PM 2.5 ), black carbon (BC), nitrogen dioxide (NO 2 ), and ozone (O 3 ), as well as PM 2.5 Boston, MA: Health Effects Institute. particle composition.

HEI study finds no heart effects of ozone exposure in healthy older adults; lungs affected at relatively low exposures

Green Car Congress

The largest systematic study ever conducted of human volunteers exposed to ozone air pollution has found no evidence of effects on the heart in its healthy, older participants, but did find effects on the volunteers’ ability to breathe, even at low ambient levels. Possible pathways by which ozone may cause adverse health effects.
