">Toxic air pollutants are substances that can cause cancer or other major health effects like birth defects, lung defects or reproductive defects when they enter the human body. They are also called hazardous air pollutants in some sources. Examples of notable toxic air pollutants are methylene chloride, used as a paint stripper and solvent by several industries; benzene, a compound that is found in ample amounts in gasoline, and perchloroethylene, a chemical that is emitted from certain dry cleaning facilities. Some of the other forms of air toxins include toluene, asbestos, dioxin and metals such as chromium, mercury, cadmium and lead compounds. When people are exposed to significant levels of air toxins for a considerable period of time, they may have a higher propensity to develop cancer or other conditions that may cause permanent damage to their health or even death. These health effects may include damages to a person’s immune system, reproductive system, neurological system, respiratory system and hamper developmental growth. Most of the air toxins come from manmade sources, including stationary sources like power plants, refineries and factories; mobile sources or vehicles like buses, cars and trucks; and indoor sources like some cleaning solvents and building materials. Air toxins can also originate from natural sources like forest fires and volcanic eruptions. Air toxins can enter the body in a number of ways, such as • By breathing contaminated air; • By eating food products that are contaminated, such as milk, eggs or meat from animals that consumed contaminated plants and grains; • By drinking contaminated water; • By ingesting contaminated soil; • By touching contaminated water, dust or soil In order to control toxic air levels, it is necessary to understand from where toxins are generated and then control such sources. Some of the most notable sources of toxins include industrial sectors, such as oil refineries, chemical plants, steel mills, aerospace manufacturers, commercial sterilizers, secondary lead smelters, chromium electroplating facilities and dry cleaners. Emissions from these sources should be controlled and monitored regularly to keep air toxin levels at check. Special attention needs to be given on tailpipe emissions from cars, trucks and other vehicles. Reformulated gasoline should be used to lessen the concentration of toluene, benzene and other forms of air toxins from vehicle emissions. To improve the indoor air quality of offices, schools, homes, and other indoor spaces, special air purifiers are needed to be used. There are many mobile apps available these days to check and monitor air toxic levels of the cities. If you are travelling to different cities if the world, you need to know the air toxic level of the cities. For this you can refer to the WORLD AQI mobile apps.
