Description:A survey was conducted to investigate the feasibility of detecting effects of sewage sludge disposal at the 106 Mile Deepwater Municipal Sewage Sludge Disposal Site (106 MDS) using mid-water fish as sentinels of the introduction of sludge-derived contaminants into the offshore food web. Metal concentrations in the myctophid, Benthosema glaciale, collected in the dumpsite were statistically significantly higher than concentrations in the same species from a control station near Block Canyon and concentrations in other species collected in the dumpsite and control areas. Results suggest that uptake occurred through direct (short-term) exposure to sewage sludge dumped at the site. Additional field sampling and laboratory analyses are necessary to verify this inference.
