| Abstract |
Talitrid amphipod crustaceans are increasingly being used as biomonitors of trace metal bioavailabilities in coastal waters, and it is important to understand how other factors, in addition to metal pollution, might affect their accumulated body concentrations. Seasonal variation (April–October 2000) in body concentrations of copper, zinc, cadmium, iron, manganese, lead and nickel has been investigated in three species, Orchestia cavimana, Talitrus saltator and Talorchestia deshayesii, from the region of the Gulf of Gdansk (including the Vistula Lagoon), Poland, an area with considerable temperature variation between summer and winter. Seasonal variation in the body metal concentrations of talitrid amphipod crustaceans was confirmed in each population, but only copper showed a consistent pattern. Copper concentrations fell from early to late summer, perhaps either as a result of the replacement of the older overwintering generation by the younger spring one, or as a result of the loss of haemocyanin in autumn amphipods entering a period of low metabolic activity. Metal concentration data for T. saltator from Gdynia-Osada Rybacka compared with equivalent data for 1996 and 1998 show a significant drop in metals associated with the influx of the Vistula river water, which occurred in 1998, following a major flood event in 1997. |
