... HISTORY/BACKGROUND--- During the Carboniferous period, which was about 300 million years ago, the weather was much warmer and wetter due to the high concentration of carbon dioxide present in the air. The high amounts of CO2 in the air made it a favorable place for plants to live. Also because of ...
Photochemical smog and environmental pressures.
... Secondary pollutants are those which have been formed when the primary pollutant of the photochemical smog undergoes further reaction, by the heat of the sun; example: ozone. NOx and NO2 are the main primary and secondary pollutants produced respectively from motor vehicles. A coal fired power ...
