摘要: Whole Antarctic krill, Euphausia superba collected along the Western Peninsula, were analyzed for 14 elements. Average element abundances (in parentheses) in μg/g, descending order, as follows: P(9940), Cu (80.5), Zn (43.5), Fe (28.0), Se (5.80), Ba (3.78), Mn (1.98), As (1.92), Ag (1.71), Ni (0.54), Cr (0.30), Cd (0.29), Pb (0.22), and Hg (0.025). Inverse relationships found between krill length concentration well P levels. A geographic trend of increasing levels from southwest to northeast Peninsula was Sound. Results compared earlier data evidence metal changes due anthropogenic activity over last 15 years.
