EFFECTS OF METALS AND ORGANIC-COMPOUNDS ON SURVIVAL AND BIOACCUMULATION IN 2 SPECIES OF MARINE GAMMARIDEAN AMPHIPOD, TOGETHER WITH A SUMMARY OF TOXICOLOGICAL RESEARCH ON THIS GROUP

The toxicity and bioaccumulation of arsenic, cadmium, copper, lead, me rcury, zinc, DDT, PCB and the water-soluble fraction of diesel fuel to the gammaridean amphipods Corophium insidiosum and Elasmopus bampo we re measured, At 96 h exposure C. insidiosum was more sensitive to arse nic, zinc, DDT, PCB and the water-soluble fraction of diesel fuel than E. bampo, whereas E. bampo was more sensitive to cadmium, chromium an d copper than C. insidiosum. Over a 20-day period C. insidiosum accumu lated greater amounts of chromium, copper, lead and zinc than E. bampo , whereas E. bampo accumulated more cadmium, DDT and PCB than C insidi osum. The toxicity and bioaccumulation of toxicants to other species o f marine gammaridean amphipods are tabulated.
