Document Summary
Eesa- lecture 10- atmospheric pollution and global climate change. Volatile = it can go from gas to liquid to solid easily. They last in the environment for a very long time. Can have detrimental effects at low concentration. Read it- largely talked about ddt on bird reproductive capabilities. Mercury and lead: some gets into the atmosphere as particulate and some as a gas. High amounts of mercury found in breast milk of polar bears and inuit people. Used to be leaded gas and non leaded gas. Most of the pollutants that come from cars react with something else and create something worse. Ozone (o3) is what smog is essentially. There is no such thing as a hole in the ozone= it is actually just a thinning or lessening of the ozone in the stratosphere above the antarctic. There was a huge global change when the world realized that there was a thinning in the ozone.
