The Acid Rain In Jiangxi Province Of Hydrogen, Oxygen, Sulfur Isotope Characteristics And Origin

Jiangxi province is one of province of acid rain pollution is serious, the acid rain is atypical acid rain, acid rain in Jiangxi province serious strip shaped like an "R"distribution.This paper selects Jiangxi province Nanchang City, Fuzhou City, Yichun city isa typical acid rain research area, systematic collection of three above the city in2010theannual precipitation samples, analysis of the pH value of the sample, cationic and anioniccomponents, system test of atmospheric precipitation in a sample of hydrogen, oxygen,sulfur isotopic composition, research in different areas of Jiangxi province acid rain sulfursource of acid rain in Jiangxi Province, discusses the formation, transportation anddeposition mechanism, we obtain the following conclusions:(1) Master of the Jiangxi Province, Nanchang City, Fuzhou City, Yichun City2010precipitation D D, Delta18O values of temporal and spatial variation rule;(2) Master of the Jiangxi Province, Nanchang City, Fuzhou City, Yichun City, Delta34Svalue of precipitation temporal and spatial variation rule;(3) through the research that coal and oil produced during the combustion of SO2, NOXand other acidic pollutants, is in Jiangxi province Jiangxi province Nanchang City, FuzhouCity, Yichun City, the sulfur isotopic composition of precipitation is the main source ofsulphur;(4) research indicates that Jiangxi province Nanchang City, Fuzhou City, Yichun city in2010than in2009precipitation acidity of precipitation acidity, the frequency of acid rain isalso on the rise, and the overall trend coincides with Jiangxi province.(5) the Jiangxi province soil belongs to South acid soil, into the atmosphere soil particleson precipitation acidity buffer capacity is weak; Jiangxi Province, north of Yangtze River,East, South, West Hills on three sides, easy to form the mountain inversion, is notconducive to acidic pollutants spread upward, making the local area acid increasingpollutant concentration; Jiangxi industrial structure is endless and reasonable, mainindustrial energy is of high sulphur coal and oil, which is the reason of serious pollution ofacid rain in Jiangxi province.The above understanding, to guide the prediction of acid rain in Jiangxi Province,prevention, management has an important guiding significance.
