EESA10H3 Chapter Notes - Chapter 2: Plywood, Byssinosis, Endocrine Disruptor
Air pollution = pollution of the troposphere: e. g. combustion products of burning fossil furls, combustion = chemical reaction that requires a hydrocarbon fuel, oxygen, and initial source of heat. Heat causes hydrocarbon fuel to break down and recombine with oxygen forming h2o and co2. Oxidation reaction releases heat energy cause combustion to continue as fuel remains. When not enough oxygen for hydrocarbon fuel to burn, co is release instead of co2. Production of electric power, whether from fossil or nuclear fuels has environmental impacts of different sort: ex1. When water is taken from a natural source for plants uses for cooling, it may be released back to the water source, but the temperature may still be higher than normal = thermal pollution: ex2. Various combustion processes produce many of the same pollutants although their profiles vary. Because combustion is oxidation, combustion of fossil furls produces several oxides: co2 from cars, electric power plants, heating buildings, manufacturing, co from vehicles.
