Document Summary
Good ozone is good b/c in stratosphere, protects from uv rays. Just as important as detritivores in recycling nutrients. Nitrogen, oxygen, water vapour, co2, argon (greatest to least) Vocs + no(x) + sun = bad ozone. Volatile organic compounds + nitrogen oxide + sun = bad ozone. Bad ozone is a pollutant, good ozone isn"t. Pollutant = any chemical that at a high enough level will cause damage. Natural- dust, vocs from plants, plant decay, forest res, volcanoes, sea spray-->sea mist contains salt! When each source emits a pollutant, it is considered a primary pollutant. The more uv that enters troposphere to create photochemical smog. No(x) + vocs + heat + uv = 100s pollutants, (including bad ozone) Smog can affect people w/ weak immune systems, other ailments-->asthma. Can also cause respiratory distress on other individuals, stinging of eyes. But vocs on their own won"t cause much smog. Therefore trees that produce high vocs shouldn"t be in urban areas.
