Study finds pollution emitted near equator has biggest impact on global ozone

Green Car Congress

They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane. Based on their findings, they suggested that emission increases in Southeast, East and South Asia may be most important for the ozone change.

Study suggests air pollution may be linked to heightened mouth cancer risk; PM2.5 and ozone

Green Car Congress

High levels of air pollutants, especially fine particulate matter (PM 2.5 ) and to a lesser extent, ozone, may be linked to a heightened risk of developing mouth cancer, suggests a study by a team of Taiwanese researchers. A significant association was also observed for ozone levels below 28.69-30.97 µg/m 3 , those above 40.37

Study finds rising emissions of ozone-depleting CFC-11, banned by Montreal Protocol

Green Car Congress

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. Measurements from Hawaii indicate the sources of the increasing emissions are likely in eastern Asia.
