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. The number of new cases, and deaths from, mouth cancer is increasing in many parts of the world. A significant association was also observed for ozone levels below 28.69-30.97 parts per billion.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Ramanathan concludes that full implementation of existing emissions-control technologies could offset the warming effects of one to two decades of carbon dioxide emissions.
