Study On Pollution Characteristics Of Acid Rain In Panzhihua And It's Prevention Measure Against Acid Rain

Today, Acid rain is one of important environmental questions of the earth. In the 70 age of 20^th century, Chinese economy is developing with 8% rate, the fossil fuel is more and more used, a great deal of acid matters are letting, acid sections are formed in the south of the ChangJinang River and the east of the SiChuan Basin. It is the third-larget acid sections except the europeand the North America, include the U.K ,France,Germany and U.S,Canada. moreove it's rate and expanding area are egregious. Acid precipitation is more and more higher. It is few in the word,and stirring up our misgivings.Now, scientist calls acid rain is Azrael of air and killer of invisibility. It has bringed huge wreck and effect to biogeoceno,enturonment and human produce and life. Moreover it works imponderable economic losing.Panzhihua is economic center of soutnwest of china, and important base of energy sources and raw and processed materals of economic section in the Changjiang valley. it's industries are mainly using coal, SO₂ infectant in atmosphere mainly comes form burning coal. At one time, along with rapid development of traffic, the fuel is master source of NO₂ infectant in atmosphere. These acid matters are making acid pollution. In Panzhihua, precipitation has been measured in more times, but acid pollution is been ignored by governmentand environmental department, via the study of character and prevention measure of acid pollution, it is propitious to grasp actuality and character, also via analyse of cause of formation, it is propitious to constitute valid prevention measure against acid rain, it is important meaning to protecting environment.The result shows that Distributing space of acid rain is different in Panzhihua, pollution of acid rain in Bingcaogang is more bader than other one, and the suburb is bader than cantonal area, no industrial park is bader than industrial park.acid rain in Panzhihua is vitridic model, SO42" and Ca2+ is the most important ions to adjust acidity of precipitation, rainfall is acidic due to geographical conditions, weather and alkaline matters, in addition to the influence of local atmospheric SO2 pollution. Acid pollution of Panzhihua especiaiiy in Bincaogang has trend of aggravation, Although acid pollution of Panzhihua is not higher than other one of china, but it is influenced by energy source and landform and weather. And all that.we must think must of acid pollute adequately.it is very pivotal to control acid pollution that we are more supervising and managing to environment.cortroling and cutting gross of SO2 is a basal approach of keeping acidification of precipitation within limits.
