    Historically, the term smog referred to a mixture of smoke and fog, hence the name smog. The industrial revolution has been the central cause for the increase in pollutants in the atmosphere over the last three centuries. Before 1950, the majority of this pollution was created from the burning of coal for energy generation, space heating, cooking, and transportation. Under the right conditions, the smoke and sulfur dioxide produced from the burning of coal can combine with fog to create industri...

    Since the invention of the automobile, man has put on this earth millions upon millions of cars. These automobiles that we so frequently use, are now polluting the environment we live in. Our cars are now the single greatest contributors of poisonous gases in our environment today. These poisonous gases not only take their toll on the environment, but they also have a harmful affect on our lives as well. These gases create many serious environmental problems, which in turn affect the health of a...

    Catalysts & Fine Particle In Industry Catalyst: Catalysis, alteration of the speed of a chemical reaction, through the presence of an additional substance, known as a catalyst, that remains chemically unchanged by the reaction. Enzymes, which are among the most powerful catalysts, play an essential role in living organisms, where they accelerate reactions that otherwise would require temperatures that would destroy most of the organic matter. A catalyst in a solution with-or in the same phase as...

    Acid rain is normal rain to begin with; the kind rain people once loved singing in. When water vapor combines with pollutants in the air and reaches a pH level less then 5. 6, it turns deadly, into acid rain. Acid rain is responsible for many of the serious environmental problems. It is the very thing that one-day may kill us all. When factories burn coal and oil, which contain large amounts of sulfur, sulfur dioxide is formed. The exhaust from gasoline-powered vehicles contains nitric oxide. W...
