Air Pollution Essay 24

What atomic number 18 the do and sources of convey pollution appointment III Rachita Mittal Western International University SCI 270 Mrs. Saudamani Sharma Introduction direct pollution is the mental home office of chemicals, particulate thing, or biological materials that cause harm or provocation to humans or separate living pipe organisms, or damages the indispensable environment, into the automated teller. The atmosphere is a complex, dynamic natural muffeous system that is congenital to support life on planet Earth. Stratospheric ozone depletion due to convey pollution has long been recognized as a threat to human wellness as well as to the Earths ecosystems.History Humans probably head start experienced harm from air pollution when they built fires in badly ventilated caves. Since then we have gone on to pollute more(prenominal) of the earths surface. Until recently, environmental pollution chores have been local and minor because of the Earths own mogul to a bsorb and purify minor quantities of pollutants. The industrialization of society, the introduction of motorized vehicles, and the outburst of the population, ar factors contributing toward the growing air pollution problem. At this cartridge clip it is urgent that we find methods to clean up the air.The primary air pollutants undercoat in most urban areas are carbon monoxide, nitrogen oxides, sec oxides, hydrocarbons, and particulate matter (both solid and liquid). These pollutants are dispersed throughout the worlds atmosphere in concentrations high enough to gradually cause serious health problems. Serious health problems potful occur quickly when air pollutants are concentrated, such as when massive injections of sulfur dioxide and suspended particulate matter are emitted by a large volcanic eruption. Air pollution in the HomeYou cannot escape air pollution, not even in your own home. In 1985 the Environmental Protection Agency (EPA) reported that hepatotoxic chemicals found in the air of almost every American home are three clocks more likely to cause slightly type of cancer than outdoor air pollutants. (Miller 488) The health problems in these buildings are called sick building syndrome. An estimated one-fifth to one-third of all U. S. buildings are straight off considered sick. (Miller 489) The EPA has found that the air in some office buildings is speed of light cartridge clips more polluted than the air outside.Poor ventilation causes near half of the indoor(a) air pollution problems. The rest come from proper(postnominal) sources such as copying machines, electrical and telephone cables, mold and microbe-harboring air conditioning systems and ducts, cleaning fluids, cigarette smoke, carpet, latex caulk and paint, vinyl molding, linoleum tile, and building materials and furniture that emit air pollutants such as formaldehyde. A major indoor air pollutant is radon-222, a colorless, odorless, tasteless, naturally occurring radioactive ga s produced by the radioactive decay of uranium-238. According to studies by the EPA and the National enquiry Council, exposure to radon is second only to smoking as a cause of lung cancer. (Miller 489) Radon enters through pores and cracks in concrete when indoor air pressure is less than the pressure of gasses in the soil. Indoor air will be healthier than outdoor air if you use an zero rec everywherey ventilator to provide a consistent supply of recent filtered air and then seal air leaks in the shell of your home.Air pollution has unhealthy takingss on people, animals and plant-life across the globe. Every time we inhale, we carry dangerous air pollutants into our bodies. These pollutants can cause short-term effects such as eye and throat excitement. More alarming, however, are the semipermanent effects such as cancer and damage to the bodys immune, neurological, reproductive and respiratory systems. Acid Rain is a significant air pollution problem that affects rural, suburb an and urban areas that are down-wind of major industrial areas.Acid fall is caused when sulfur and nitrogen pollution from industrial smokestacks is combined with moisture in the atmosphere. The resulting rain is acidic which destroys natural ecosystems ands buildings. Global Warming, as pollution gathers in the Earths atmosphere, it traps heat and causes average temperatures to rise. It is hard to predict exactly how climate deviate will affect a particular area. Here are a few likely results A rise in sea take between 3. 5 and 34. 6 in. 9-88cm) leading to more coastal erosion, fill up during storms and permanent inundation Severe puree on many forests, wetlands, alpine regions, and other natural ecosystems Greater threats to human health as mosquitoes and other disease-carrying insects and rodents spread diseases over larger geographical regions Disruption of agriculture in some parts of the world due to increased temperature, water stress and sea-level rise in depressio n-lying areas such as Bangladesh or the Mississippi River delta.
