Today we review research that established a link between the aerosols or tiny particles that are emitted by a number of sources both natural and man-made and the chemical process with the pollutant, alpha-pinene, released by pine trees. The result is three times more particulates than what was originally emitted – and three times the health impact on humans.
Key Quotes:
“aerosols.. tiny liquid or solid particles come from hundreds of sources including trees, volcanoes, cars, trucks and wood fires”
"There's a very, very strong body of data that establishes that fine particles in the air we breathe have a significant bad effect on people. What is less well understood is how the size and chemical composition of those particles influences that effect,"
“OH [hydroxyl] ages the particles, altering their properties and concentrations and producing three times more particulate matter than what was originally released into the atmosphere”
"The trees emit the stuff, but since human activity changes the chemistry taking place in the atmosphere, those changes can affect the amount and properties of the natural aerosols”
“OH ages the particles, altering their properties and concentrations and producing three times more particulate matter than what was originally released into the atmosphere”
