Pollution the Air
Pollution the air (Air Pollution) is the introduction of particulate matter, chemicals, or biological materials that cause harm or discomfort to humans or other living organisms, or that damages the natural environment, into the atmosphere. The atmosphere is an extremely complex, dynamic natural gaseous system that is integral to support life on planet Earth. Stratospheric ozone depletion that is due to pollution the air has long been recognized as a threat to human health and to to the Earth’s ecosystems. Before flue gas desulfurization was installed, the emissions from this particular power plant in New Mexico contained excessive amounts of sulfur dioxide. The schematic drawing shows the causes and effects of pollution the air: (1) greenhouse effect, (2) particulate contamination, (3) increases in UV radiation, (4) acid rain, (5) increased ozone concentration, (6) and increased levels of nitrogen oxides
Pollution the air is known as a substance in the air that can cause harm to humans as well as the environment. Pollutants can be in the form of liquid droplets, solid particles, or gases. In addition, they may be natural or man-made. Pollutants can be classified as primary or secondary. Typically, primary pollutants are substances that are directly emitted from a process, such as the ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or even sulfur dioxide released from factories.
Secondary pollutants aren’t emitted directly. Rather, they form in the air when primary pollutants interact or react. Another important example of a secondary pollutant is ground level ozone, which is one of the many secondary pollutants that make up photochemical smog. Note that certain pollutants may be both primary and secondary: that is, they are both emitted directly and then formed from other primary pollutants. About 4 percent of deaths in the United States could be attributed to pollution the air, according to the Environmental Science Engineering Program at the well known Harvard School of Public Health.
Lack of ventilation indoors concentrates air pollution where people frequently spend the majority of their time. Radon gas, a carcinogen, is exuded from the Earth in certain locations and is trapped inside of houses. Building materials including carpeting and plywood emit formaldehyde gas. Paint and solvents emit volatile organic compounds (VOCs) as they dry. Lead paint can degenerate into dust and then be inhaled. Intentional air pollution is introduced with the use ofincense, air fresheners, and other scented items. Controlled wood fires in fireplaces and stovescan add noteworthy amounts of smoke particulates into the air, inside and out. Indoor pollution fatalities can potentially be caused by using pesticides and other chemical sprays indoors where there is not proper ventilation.
