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. In 2012-13, 1617 cases of mouth cancer were diagnosed among the men. But so too were high levels of PM 2.5.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming. Ramanathan, Kevin Hicks, N. doi: 10.1126/science.1210026.
