Forest Decline Due to Particulate Matter
June 19, 2013 05:11 PM - Andy Soos, ENN
Forests and plants in general can remove pollutants but may be at a hard cost. Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Bonn University scientists have now discovered a responsible mechanism: particulate matter salt compounds that become deliquescent because of humidity and form a wick-like structure that removes water from leaves and promotes dehydration. These results are published in Environmental Pollution.
