Pollution

A:

There are two recognized types of smog, which are sulfurous smog and photochemical smog. Sulfurous smog is a high concentration of sulfur oxides in the air. Photochemical smog is nitrogen oxides and hydrocarbon vapors emitted by automobiles and other sources, which then undergo photochemical reactions in the lower atmosphere.

  • Why are aerosol cans bad for the environment?

    Q: Why are aerosol cans bad for the environment?

    A: A well-known campaign against chlorofluorocarbons in aerosols in the 1970s led to continued association of the chemical with aerosol sprays. However, this issue was entirely resolved, and aerosols are no longer a threat to the ozone layer. However, they are still not beneficial to the environment as they are one of many products that contribute to global warming and smog problems.

  • Q: What are causes of thermal pollution?

    A: Thermal pollution primarily arises from waste energy generated from power plants, although it also comes from shoreline erosion, deforestation and runoff from paved surfaces. Thermal pollution refers to an artificial change in temperature, generally an increase from the average, in water bodies such as lakes, rivers, oceans and streams. This change in temperature stems from human activities such as the burning of coal and other fossil fuels and release of toxic byproducts into surrounding waters.
