Distribution and Source Apportionment of Heavy Metals in Soil around Dexing Copper Mine in Jiangxi Province, China

The soil heavy metal pollution around the mine threatens crop growth and human health. Intensively studies of distribution characteristics source metals some typical mines are very crucial for environmental management green development mine. A total eighty-nine samples, twenty-one sediment five waste rock samples two tailing sand were sampled to investigate copper (Cu), lead (Pb), zinc (Zn), arsenic (As), cadmium (Cd), chromium (Cr) mercury (Hg) in soil, sediment, rocks tailings Dexing Copper Mine, Jiangxi Province, China. concentrations seven determined using inductively coupled plasma mass spectrometry ICP-MS/atomic fluorescence spectroscopy (AFS). Igeo values showed that 100% Cu at an unpolluted-to-moderately-polluted level (Igeo > 0), more than 50% heavily polluted 3), 65.16%, 22.47%, 7.86% 7.87% Cd, Hg, As Zn overly moderately 1). 13.48% 11.24% Pb Cr, respectively, (1 < 2). Compared with Risk Screening Values Contamination Agricultural Land (RSVCAL), concentration 97.75% Cu, 69.21% Cd higher RSVCAL. In Dawu river basin According RSVCAL, soils Mine by extent, especially being most serious. These exceeding RSVCAL have threatened safety agricultural products. results profile analysis, principal component analysis (PCA) cluster (CA) indicated mining activities should be main soil. High obviously caused as well. addition, partly account Zn, Pb, Hg Cr
