about ozone
GHG, potent poison, absorbs UV
when is ozone formed
when pollutants emitted by cars, powerplants, industrial boilers, refineries, chemical plants and other sources chemically react in presence of sunlight • NO2 reacts with sunlight to form NO and O. oxygen collides with O to form O3 - so when sun goes down it stops • cyclic reaction. nothing destroyed just converted back and forth
major sink for NO2?
atmospheric oxidation
effects of ozone/smog on health
cilia broken down/dissolve so breathe in particulate matter and get holes in lungs - dangerous to go on runs in cities effects plants too
