Document Summary

There are large parts of the world that suffer from n deficiency. Halocarbons- compounds containing carbon and either chlorine, bromine, or fluorine. Hcfc"s- hydrochlorofluorocarbons: cfc replacement, less table form of cfc"s. Co2 aerobic respiration emits into the atmosphere, photosynthesis and dissolution removes it. Ch4 is emitted into the atmosphere through anaerobic respiration. Cfc"s: there are no natural sources, they are all manmade. Co2 fossil fuel combustion, deforestation, and cement production emit it into the atmosphere. Ocean uptake and forest uptake remove some of it. Ch4 landfills, fossil fuel combustion, and animal production emit it into the atmosphere. Oxidation to co2 removes it from the atmosphere. Cfc"s diffusion into stratosphere were it is destroyed in chemical reaction (contributes to ozone depletion) Co2 contributes to the greenhouse effect and ocean acidification. Cfc"s contribute to the greenhouses effect and stratospheric ozone depletion. In the greenhouse effect, the order of importance is co2 > ch4 > cfc"s.
