The main causes of air pollution include the emission of greenhouse gases, such as carbon dioxide, methane, and chlorofluorocarbons, emission from volcanic eruptions and toxic air pollutants emitted by vehicles. The amount of smog as well as the damaging effects on health and the environment indicate the severity of air pollution.Know More
Although it’s also produced through the breathing process, the vast amount of carbon dioxide responsible for air pollution comes from activities that include the burning of fossil fuels such as gasoline. As of 2014, the amount of carbon dioxide that has been released into the atmosphere by vehicles and power plants in the past 150 years has negatively contributed to global warming.
Methane comes from sources such as swamps and is a result of the digestion process in livestock. Chlorofluorocarbons had been used as refrigerants and aerosol propellants before they were banned on account of their harmful effect on the ozone layer.
The process of vehicle manufacturing, refueling and disposal creates two forms of air pollution: primary and secondary. Primary pollution affects the atmosphere directly, while secondary pollution functions through the interaction between different pollutants in the air. Particulate matter is a result of diesel exhaust and secondary pollution caused by hydrocarbons, nitrogen oxides, and sulfur dioxides. It consists of small particles of soot and metal that can severely impact a person’s health because they are able to penetrate deep into the lungs.Learn more in Pollution
Air pollution levels may be reduced at home and the office by conserving energy, planting deciduous trees, recycling paper and plastics and keeping automobiles maintained. Air pollution stems from many sources, which makes it difficult to prevent it from entering into the atmosphere altogether.Full Answer >
In the United States, the amount of air pollutants in the atmosphere can be directly measured by anyone using instruments such as the GASPer air quality monitor, area's immediate reading, or AIR device and sun photometer. Common examples of air pollution include smog, vehicular and power plant emissions and acid rain.Full Answer >
Air pollution stems from the addition of unnatural compounds and toxins through indirect and direct mechanisms. Direct sources of air pollution include electricity, fuels and transportation, while indirect sources are goods and services that require energy to produce and deliver, such as vehicles and household appliances.Full Answer >
Air pollution affects the environment by causing acid rain, reducing visibility, damaging plants and animals, and contributing to climate change. It has a negative effect on biodiversity and the survival of species. Air pollution is caused by both particulate and gaseous pollutants.Full Answer >
