_____________________ According to the Phoenix Laboratory of U .S . Environmental Protection Agency (EPA , air pollution is responsible for affecting respiratory function resulting in premature deaths . Phoenix is susceptible to umpteen preexisting respiratory or cardiovascular conditions and asthmatics to 9 .7 of its population , which consists mostly of elderly people aged 65 and above (Koenig et al , 2000 ) According to the latest Phoenix report , over 79 , of the county 's residents are at high risk for respiratory

complications due to air quality which includes asthma bronchitis , cardiovascular disease , and diabetes (Eastwood , Jan2006

For decades , Phoenix is suffering from the threat of Brown layer which starts surrounding the entire Phoenix with sunset . This brown shield ' is composed of carbon and nitrogen , which is considered as a dangerous air pollutant , and when combined with other gases Water and air pollution visibility problems have been tremendously increasing in Phoenix since 1990 . The main reasons behind this refer to the photochemical smog attributed to local industrial and urban pollution during warm months . The problem of regional haze also contributes in making the pollution situation progressively worse . This is caused by long-range transport of pollutants from a variety of large and small sources undergoing chemical and photochemical transformations in the presence of abundant sunlight , warm temperatures , high relative humidities , and stagnant high-pressure systems . Most optically active components of such hazes are sulfate aerosols . The visibility reduction in pristine mountain areas of scenic beauty has been of greatest concern to public as well as regulatory agencies . In particular , open vistas in national parks have to be protected against the long-range transports of pollution

As far as the hygiene is concerned , given sufficient time and distance an impacted stream or river might cleanse itself . Water pollution can be alleviated by making metals attempt to settle from the moving water as minute crystalline precipitates , or more likely , adsorb onto suspended sediments , including other suspended precipitates . Combine this natural diminution with inflows from uncontaminated tributaries and you have the basis for the grizzled polluter 's adage , According to Stiller (2000 Dilution is the solution to pollution (Stiller , 2000 ,

This is possible both with waste rock and mill tailings . Until the past decade or two , such practices were not part of a mine 's normal functioning and minerals processing operations But today , under the watchful and encouraging eye of modern state regulatory agencies , industry frequently incorporates methods of isolating the most pyritic materials and sealing them against water or oxygen in to keep the environment aloof from pollution (Stiller 2000 ,

Water based natural systems integrate environmental values into human activities . Humans need to use natural resources for their sustenance and humans know how to use resources to enhance and improve their lives On the other hand , when these...
