Comparative Concentrations of Metals in Marine Species form French Frigate Shoals, North Pacific Ocean

摘要

Concentrations of arsenic, cadmium, chromium, copper, lead, mercury, selenium, and zinc were measured in coral, crab, eel, fish, lobster, and sediments samples collected from French Frigate Shoals, North Pacific Ocean. The sedi- Ments contained relatively high concentrations of selenium; Moderate concentrations of arsenic, cadmium, copper and Lead; and low concentrations of chromium and zinc. Metal Concentrations were also determined in coral and crabs Collected form the island of Oahu. Notably, a crab (Grapsus tenuicrustatus) and the undulated moray ell (Gymnothorax undulatus) exhibited high levels of copper and arsenic, respectively, relative to the other species studied.
