Abstract

This study investigated 12 trace elements in paired green turtle (Chelonia mydas) eggshell composites and coral sand samples to examine within-habitat heavy metal pollution from 40 nesting sites in the Xisha Islands. The concentrations of the elements (μg·g-1) found in the eggshells ranged as follows: Sr (41.3) > Zn (20.3) > Cu (12.8) > Fe (4.92) > Al (4.37) > Se (2.44) > Mn (0.91) > Cr (0.81) > Ba (0.44) > Pb (0.14) > As (0.08) > Cd (0.02). Significant correlations were observed between the levels of Cd and Se and the levels of Zn, Cu, and Pb in eggshells. The concentrations of Mn, Zn, Se, As, Cd, and Pb in C. mydas eggshells were significantly correlated with those in coral sand sediments. Cu concentrations in the eggshells exceeded the toxic reference value for bird eggs and Se concentrations were between the worst- and best-case scenario hazard quotients.
