Abstract

Because of their wide geographic distribution, position in the trophic chain, rapid turnover, huge biomass and role in ocean biogeochemical cycles, copepods are regarded as important marine test species. Tigriopus brevicornis Muller, 1776 is a shallow water benthic marine species (Crustacea, Copepoda Harpacticoida). The toxicity of essential and non-essential metals (Ag, Cd, Cu, Hg, Ni and Zn) to Tigriopus brevicornis was determined by 96-h LC50testing. Comparative crustacean 96-h LC50 data in the literature show thatTigriopus brevicornis is a sensitive species suggesting that copepods are good indicators of minimal lethal concentrations of metals. Groups of 1000 to 1500 adult copepods were exposed for 1 to 14 days to metals at concentrations in water, 3 for each metal, considered realistic in comparison with those encountered in polluted environments and far below lethal concentrations, in order to avoid protein metabolism disturbance. The response of Tigriopus brevicornis in terms of MT induction has been examined in specimens exposed to metals. The induction of these proteins and their implication in detoxificatory mechanisms and trophic transfer are discussed. (C) 2001 Elsevier Science Inc. All rights reserved.
