Title: Analysis of Characteristics and Sources of Acid Rain in Shenzhen City
Abstract: The temporal-spatial distribution,chemical composition,and the source analysis of acid rain in Shenzhen City from 1991 to 2004 were studied in this paper.It was shown that the average pH value of Shenzhen acid rain during 14 years,the frequency was about 44.2%.The ratio of SO24 to NO-3 was 3.78∶1,lower than the average pH value of whole country. Acid rain was more serious in Shenzhen during Summer and Autumn,mainly occurring from March to September,in contrast,the frequencies of acid rain in Winter and Spring were less than those in Summer and Autumn.The intensity of acid rain decreased from west to east.The sources of ions in acid rain mainly came from the acid pollutants of industrial and traffic emission,but the influences of land and ocean sources were also bigger.
