Document Summary
Natural air pollution sources produce a greater quantity of pollutants than do human- made sources. Big difference is we adapted to deal with natural sources over time. At any one moment, a billion tons of dust are carried by the winds in our. Layer where lapse rate is much less (cooling slower). Often from pollution: surface temperatures stay colder. atmosphere. Form when primary pollutants interact or react with other elements in the atmosphere. Read table 3. 4 in book carbon monoxide, nitrogen oxides, sulfur oxides, Responsible for hazy sky and reduced sunlight in cities. Air pollution associated with coal-burning is industrial smog. Sulfur dioxide (so2) reacts with oxygen to form sulfur trioxide. In the presence of water forms sulfur aerosols, sometimes even sulfuric acid. Pollutants react with water to produce low ph compounds (e. g. nitric acid) The wet/dry deposition of pollutants on land. Acid rain, as well as sleet, hail, etc. Paying for what was done in the past.
