If you would like to help reduce air pollution you can take the following measures:
  • Eliminate tobacco smoke.
  • Reduce your use of wood stoves and fireplaces.
  • Don’t burn candles leaves garbage plastic or rubber.
  • Use HEPA air filters and air cleaners designed to reduce particles.

What are the most common pollutant particles suspended in air at home and outdoors?

The indoor environment also reflects outdoor air quality and pollution. Outdoor pollution primarily results from the combustion of fossil fuels by industrial plants and vehicles. This releases carbon monoxide sulfur dioxide particulate matter nitrogen oxides hydrocarbons and other pollutants.

How did the Clean Air Act successfully reduce SO2 emissions?

EPA’s Acid Rain Program provided bonus allowances to power plants for installing clean coal technology that reduced SO2 releases using renewable energy sources (such as solar wind etc.) or encouraging energy conservation by customers so that less power needs to be produced.

What led to Clean Air Act?

Poor visibility raised concerns while instances of acid rain made air pollution an interstate issue leading Congress to react to the crisis. The Clean Air Act was passed in 1970 tightening regulations in 1977 and making further amendments in 1990.

Is chlorofluorocarbon a criteria pollutant?

The 1970 Clean Air Act in the United States recognized seven air pollutants as being in immediate need of regulatory monitoring. Pollutants can also damage the atmosphere above Earth’s surface. … A well-known example of this damage is that caused by chlorofluorocarbons (CFCs).

What effects can stratospheric ozone depletion have on the environment?

Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface which increases the rate of skin cancer eye cataracts and genetic and immune system damage.

What actions could we take to decrease so2 and NOX?

Reducing Pollution

Scientists have found different ways to reduce the amount of sulfur dioxide released from coal-burning power plants. One option is to use coal that contains less sulfur. Another option is to “wash” the coal to remove some of the sulfur.

What factors that are causing sea level to rise Choose all that apply?

Sea level rise at specific locations may be more or less than the global average due to many local factors: subsidence upstream flood control erosion regional ocean currents variations in land height and whether the land is still rebounding from the compressive weight of Ice Age glaciers.

How is particulate matter released?

Some are emitted directly from a source such as construction sites unpaved roads fields smokestacks or fires. Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides which are pollutants emitted from power plants industries and automobiles.

What is one natural way that the Earth removes particulate matter from the air?

Atmospheric deposition is an important process that removes gases and particles from the atmosphere.

How can we reduce particulate matter?
