Olney, C., P. Schauer, S. McLean, Y. Lu, AND K. Simpson. INTERNATIONAL STUDY OF 'ARTEMIA' VIII. COMPARISON OF THE CHLORINATED HYDROCARBONS AND HEAVY METALS IN FIVE DIFFERENT STRAINS OF NEWLY HATCHED 'ARTEMIA' AND A LABORATORY-REARED MARINE FISH. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/D-82/219.
Description:
Newly hatched nauplii of Artemia from Brazil, Australia, Italy, and the United States (Utah and San Pablo Bay, California) were analyzed for chlorinated hydrocarbons. The Brazil and Australia nauplii contained very low levels of PCB and chlorinated insecticides. Italian nauplii contained the highest levels of HCB, BHCs and DDTs, while San Pablo nauplii were highest in chlordanes, dieldrin and PCBs. With the exception of 188 ppb pp-DDT in Italy nauplii, none of the residues exceeded 100 ppb on a wet weight basis. Attempts to correlate nauplii residue levels with the survival of laboratory-reared marine fish and crabs disclose no obvious component(s) which could totally account for the poorer performance of the Utah and San Pablo strains. Twelve metals, including copper, lead, and cadmium, were measured by atomic absorption and neutron activation analysis.
