Effects of Air Pollution. :
Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says. “Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).
“While we’ve made progress over the last 40-plus years improving air quality in the U.S. thanks to the Clean Air Act, climate change will make it harder in the future to meet pollution standards, which are designed to protect health,” says Kim Knowlton, senior scientist and deputy director of the NRDC Science Center.
It Lead to the following problems
Emissions from different transport modes, the burning of fossil fuels, industrial production, forest fires, aerosol use and radiation fare some of the main causes of air pollution. Such sources of emissions liberate gases and substances that are toxic for human beings, the most harmful of which are: tropospheric ozone (O3), sulphur dioxide (SO2), nitrogen dioxide (NO2), benzo(a)pyrene (BaP) and suspended particulate matter (PM). How does air pollution affect our health? Our physical and psychological wellbeing is affected differently by the kind of air pollution we are exposed to. There are many organs and bodily functions that can be harmed, the consequences including: Respiratory diseases Cardiovascular damage Fatigue, headaches and anxiety Irritation of the eyes, nose and throat Damage to reproductive organs Harm to the liver, spleen and blood Nervous system damage. Urban populations are more exposed to suffer the effects of air pollution and, in this context, people who are already ill are particularly vulnerable, as are children and the elderly.
