Abstract|The pollution situation of heavy metals in surface sediments of Nanfei River in Hefei was investigated. Selecting 8 monitoring points, the concns. of Cr, Cd, Pb, Ni, Zn and Cuin the samples were measured, and the pollution degree was analyzed and evaluated by geo-accumulation index and Hakanson potential ecol. risk index. The results indicated thatbased on the geo-accumulation index, the ecol. risk levels of the six kinds of heavy metals in Nanfei River from strong to weak was in an order of Cd, Zn, Cu, Ni, Pb and Cr;according to the Hakanson potential ecol. risk index, the risk of Cr, Pb, Ni, Zn and Cu belonged to "slight" level, while the risk of Cd was a little bit serious. From strong toweak, the ecol. risk order of the heavy metals was Cd, Cu, Ni, Pb, Zn and Cr. It could be seen that for most monitoring points, the synthetic potential ecol. risk of the heavymetals in sediments of Nanfei River belonged to "slight" level; however, for some individual points, the risk achieved middle or even high level.|
