摘要: Abstract This study reviewed the published papers and employed guideline values of USEPA (ERL ERM) China (MSQ, Class I, II, III) to assess contamination status potential toxic metals in East Sea sediment (ECS). The percentages metal concentrations exceeding ERL value follow sequences: Ni (96%) > As(71%) > Cr(53%) > Cu (19%) > Zn (2.4%) > Hg (0.5%) > Pb (0.4%) > Cd (0%). similar ranking is also seen for MSQ class I. All were less than ERM value, except which 10.3% exceeded value. potentially ecological risk from these sedimentary could be reduced because they mainly present residual fraction, not available marine organisms. It seems that too low (20.8. mg kg−1), close (18.6 mg kg−1) upper continental crust, obey.
