Mongabay: In 2004 scientists found that isoprene, a compound produced by trees to protect their leaves from oxidation and temperature fluctuations, plays a role in the production of particulate matter, tiny particles that can cause lung damage, asthma, and other health problems. The finding - which led some to argue that forests are worsening air pollution rather than helping mitigate it - was incomplete however. Researchers didn't fully understand how isoprene and air pollution was linked. A new study...

Sacramento Bee: Central Valley communities are among the hardest hit in California under a unique new misery index that provides statewide mapping on community pollution, health and well-being. The state Environmental Protection Agency on Tuesday unveiled a new environmental screening tool that reveals by ZIP code how neighborhoods are affected by pesticides, truck fumes, hazardous waste and other toxic factors. The index also tracks community health and well-being, based on such things as the...
