Environmental pollution and methods for treatment
Pollution is the introduction of contaminates into the natural environment that cause adverse change , pollution can taken the form of chemical substances or energy such as noise , heat and light. The components of pollution can be either foreign substances, enrrgies or natural occurring contaminates . pollution is often classed as point source or non point source pollution. The BlackSmith issues an annual list of the world's worst ploouted places . in the 2007 issues the ten top nominess are located in Azerbaijan, China, India, Peru, Russia, Ukraine, Zambia. There are forms of pollution , which surround us from all directions . Firstly, Air pollution :- the release of chemicals and particulates into the atmosphere common gaseous pollutants include carbon monoxide, sulfur dioxide, chlorofluoro carbons and nitrogen oxides produced by industry and motor vehicles . photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight . secondly, light pollution :- include light trespass, over –illumination and astronomical interference . Thirdly, noise pollution :- which encompasses road way noise, air craft noise, industrial noise as well as high – industrial sonar. Fourthly, visual pollution:- which can refer to the presence of over head power lines , motor way bill boards , scarred landforms ( as form strip mining) ,open storage of trash, municipal solid waste or space debris . fifthly, water pollution:- by the discharge of untreated sewage , release of waste and contaminates into surface waters, discharges of untreated domestic sewage, and chemical contaminates into surface runoff flowing to surface waters . finally, thermal pollution:- is temperature change in natural water bodies caused by human influence , such as use of water as coolant in a power plant, also radio active contaminates resulting from 20th century activities in atomic physics , such as nuclear power generation and...
