The present study aims to determine the concentrations and forms of Copper (Cu), Lead (Pb), Zinc (Zn), Chromium (Cr), Cadmium (Cd), Arsenic (As) in water sediments Xutuan mining area. geoaccumulation index (Igeo) ecological risk assessment coding (RAC) methods were used assess heavy metal pollution levels risks sediments. positive matrix factorization (PMF) model absolute principal component score-multiple linear regression (APCS-MLR) quantitatively analyze sources metals evaluated results showed good quality Cu, Cr, Zn, As mainly residual form, while Cd Pb organic matter combined form. Igeo RAC that degree higher APCS-MLR PMF models analyzed contributions natural (72.5% 25.1%) anthropogenic sources, respectively, further distinguished coal (26.4%), agricultural (21.44%), traffic (27.05%) sources.
