摘要: Major (Al) and trace metal (Cu, Pb, Zn, Cr, Ni, Cd, As) concentrations in 29 surface sediment samples from the eastern continental shelf of Hainan Island were evaluated to determine level contamination. A multivariate analysis indicated that sources As, Pb primarily anthropogenic, whereas Cu, Ni natural and/or partially anthropogenic. Enrichment factor (EF) geoaccumulation index (I-geo) values calculated assess anthropogenic contamination region. Both EF I-geo relatively elevated Cd As concentrations.
