AbstractHeavy metal concentrations in 36 samples of surface sediments from Hainan Island rivers were determined to evaluate the level of contamination in the region. Heavy metal concentrations (mg/kg) of Hainan Island rivers were in the range of 0.01-0.58 mg/kg for Hg, 0.09-0.70 mg/kg for Cd, 1.80-36.87 mg/kg for As, 15.33-69.32 mg/kg for Pb, 4.46-150.89 mg/kg for Cu, 6.64-104.95 mg/kg for Cr and 22.11-199.11 mg/kg for Zn. Contamination indices including contamination factor, enrichment factor, and geoaccumulation index, and multivariate statistical analyses indicated that Wenlan River was relatively at a considerable pollution level; Nandu, Changhua, Lingshui, Wanquan and Zhubi rivers were at a low-to-moderate pollution level; Beimen and Ningyuan rivers were at a level of relatively low pollution. Principal component analysis indicated that Cd, Pb, Cr and Zn were predominantly sourced from anthropogenic sources; whereas, Cu, As and Hg were from lithogenic sources. This study would be helpful for sustainable land use and marine management in the region.
