Car pollution, one of the leading casues of global warming.
Cars are emitting air pollution throughout their life, including when they are being operated,when their being refueled,manufactured, and when their being disposed of. There are two types of air pollution, primary and secondary. Primary pollution is emitted directly into the atmosphere, when secondary pollution results from chemical reactions between pollutants in the atmosphere.
Volcanic Gases and Their Efffects.
Magma contains dissolved gases that are released into the atmosphere during eruptions. Gases are also released from magma that either remains below ground or is rising toward the surface. in these cases gases may escape continuously into the atmosphere from the soil, volcanic vents, fumaroles, and hydrothermal systems.
Smog is a type of air pollution. It can be caused burning large amounts of coal. This smog contains soot particulates from smoke, sulfur dioxide and some other components. More modern types of smog in big cities comes from cars, and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical Smog.
Pesticides share a part of contributing to air pollution as well. When pesticides are sprayed in a certain are that whole atmosphere will be contaminated.
Factories and Industries.
Smoke from factories and industries are some of the main causes of air pollution. Once there pollutants have entered the water stream or atmosphere they can spread far beyond the factory. The most common factory air pollutants are greenhouse gases from the burning of fossil fuels. Factories contribute to water and land pollution by acidifying rain, chemical spills and disposal of toxic waste.
carbon dioxide, the most damaging greenhouse gas is released into the atmosphere from the burning of fossil fuels. Industries and electrical generating factories contribute slightly more than 50 percent of greenhouse gases.
