摘要
Abstract
Metal elementsconcentrations of surface soils taken from Heyuan central urban areaof Guangdong province were analyzed. The pollution index was calculated. The geochemical characteristics of the elements in the samples are given in this paper. Anomalies of Pb and As heavy metal elements were found in surface soil. The sources of abnormal elements are closely related to automobile exhaust and other industrial activities. The city's environmental risk index (IER) is 0.43, belong to the category of 2nd level, shows a low environmental risk.As a major light industry and tourism-oriented city, the heavy metal content in Heyuan is significantly lower than other major cities. But there are also elements of the abnormal area, should attract attention of local government and residents.关键词
