Abstract

Abstract

In Lianhua Town, the suburb of Changsha, 54 soil samples were collected, and the contents of 5 heavy metal elements including Hg, Cd, As, Pb and Cr, were measured. A comprehensive ecological risk evaluation method was used to evaluate the pollution degree of heavy metal elements in soils and their harm to human health. The results were as follows: 1) The average contents of Cd, Hg and Pb exceeded more than 1 time of the soil background value in Hunan province, and the accumulation in the soil was more obvious; the spatial variation of Cd and Pb was significant, indicating that their sources were highly disturbed; and the pollution degree of the 5 heavy metal elements was in sequence of Cd>Hg>Pb>As>Cr. 2) The potential ecological hazard of the 5 kinds of heavy metals was in sequence of Cd>Hg>As>Pb>Cr, and Cd and Hg possessed strong ecological hazards. The average value of the comprehensive potential ecological risk index had reached strong level. Cd and Hg were the main contributors in the study regional soil pollution. 3) "Hand-mouth" intake was the main way of soil heavy metal exposure. The non-carcinogenic exposure dose for children was far greater than that of the adults; the non-carcinogenic risk were within the safe limits. 4) The risk index of Cr was as hjgh as 10^-4 above, with carcinogenic risk; carcinogenic risk index of Cd and As ranged in 10^-6~10^-4, within an acceptable risk range. The pollution of As and Cr was found as the major factors affecting human health, and should be paid more attention to.
