What are the effects of air pollution? Below are a few key effects of air pollution. The last page on FactSheet has some specific air pollution incidents that are worth checking out.
Pollutant and Greenhouse gas An air pollutant is a material in the air that can have adverse effects on humans and the ecosystem. The substance can be solid particles, liquid droplets, or gases.
A pollutant can be of natural origin or man-made. Pollutants are classified as primary or secondary. Primary pollutants are usually produced by processes such as ash from a volcanic eruption. Other examples include carbon monoxide gas from motor vehicle exhausts or sulphur dioxide released from the factories.
Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact.
Ground level ozone is a prominent example of secondary pollutants. Some pollutants may be both primary and secondary: Before flue-gas desulphurization was installed, the emissions from this power plant in New Mexico contained excessive amounts of sulphur dioxide.
Schematic drawing, causes and effects of air pollution: Thermal oxidisers are air pollution abatement options for hazardous air pollutants HAPsvolatile organic compounds VOCsand odorous emissions.
Substances emitted into the atmosphere by human activity include: Carbon dioxide CO2 — Because of its role as a greenhouse gas it has been described as "the leading pollutant"  and "the worst climate pollution". Clean Air Act is deemed to regulate CO2 emissions. SO2 is produced by volcanoes and in various industrial processes.
Coal and petroleum often contain sulphur compounds, and their combustion generates sulphur dioxide. Nitrogen oxides NOx — Nitrogen oxides, particularly nitrogen dioxideare expelled from high temperature combustion, and are also produced during thunderstorms by electric discharge.
They can be seen as a brown haze dome above or a plume downwind of cities. Nitrogen dioxide is a chemical compound with the formula NO2.
It is one of several nitrogen oxides. One of the most prominent air pollutants, this reddish-brown toxic gas has a characteristic sharp, biting odor. Carbon monoxide CO — CO is a colorless, odorless, toxic yet non-irritating gas.
It is a product of combustion of fuel such as natural gas, coal or wood. Vehicular exhaust contributes to the majority of carbon monoxide let into our atmosphere.Causes, effects and solutions of air pollution: Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside.
A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. Hazardous air pollutants are those known to cause cancer and other serious health impacts.
The Clean Air Act requires the EPA to regulate toxic air pollutants, also known as air toxics, from categories of industrial facilities in two phases. IntroductionAlthough a number of physical activities (volcanoes, fire, etc.) may release different pollutants in the environment, anthropogenic activities are the major cause of environmental air .
The effects of air pollution wreck havoc on human health and our planet as a whole. Learn about what causes air pollution and how to help reduce the effects.
Air Pollution: Everything You Need. In fact air pollution is the occurrence or addition of foreign particles, gases and other pollutants into the air which have an adverse effect on human beings, animals, vegetation, buildings, etc. Oct 11, · Air pollution is a mixture of natural and man-made substances in the air we breathe.
It is typically separated into two categories: outdoor air pollution and indoor air pollution. In some instances, outdoor air pollution can make its way indoors by way of open windows, doors, ventilation, etc. What.
