Severe drought influences ozone pollution

Green Car Congress

Drought conditions can have complicated effects on ozone air quality, so to better understand the process, researchers have analyzed data from two ozone-polluted cities before, during and after the California drought. However, plants also decrease air ozone levels by taking the gas up through pores in their leaves.

Air Resources Board seeks nominations for 2014 Haagen-Smit Clean Air Awards

Green Car Congress

The California Air Resources Board is accepting applications for the 2014 Haagen-Smit Clean Air Awards. Through a series of innovative experiments he demonstrated that most of California’s smog is the result of motor vehicle exhaust and industrial smokestack pollution reacting with sunlight to create ground-level ozone.

Toyota develops tropospheric ozone-concentration simulator for South and East Asia

Green Car Congress

Toyota Motor Corporation (TMC) and Toyota Central R&D Labs., have developed a simulator able to predict tropospheric ozone concentrations across the whole of South and East Asia. Tropospheric ozone is the main cause of photochemical smog, an atmospheric pollutant harmful to human health and plant growth.

Airborne measurements show ozone-forming VOCs emissions from ethanol plant higher than government estimates

Green Car Congress

VOCs and nitrogen oxides react with sunlight to form ground-level ozone, the main component of smog. The team also observed chemical transformations of the emissions from Decatur, including formation of new particles, nitric acid, peroxyacyl nitrates, aldehydes, ozone and sulfate aerosol. —Joost de Gouw. de Gouw et al.

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 particle composition.
