چکیده انگلیسی
The shore crab Carcinus maenas, was used as a biomonitoring organism to measure the potential impact that the mining spill in the Guadalquivir Estuary (SW, Spain), in 1998 may have exerted on local biota. Female intermoult C. maenas were exposed to dissolved cadmium, copper and zinc at concentrations found in local waters following the spill (3 μg lâ1 Cd, 15 μg lâ1 Cu, 700 μg lâ1 Zn). Groups of shore crabs were exposed for 21 days to these metals, both singularly and in combination. Residues of metals were measured in gill, midgut gland and muscle tissues, together with metallothioneins in the midgut gland, at the end of the exposure period. Haemolymph samples were taken every seven days, and vitellogenin/vitellin analysed to determine the flux of these compounds. Biomarker results suggested that they would be good indicators of the effects of heavy metal environmental contamination, particularly in the case of Cd and Zn. Variation in results was obtained between responses measured in crabs exposed to single metals and those exposed to combinations of metals.
