“…Besides this, no significant differences were observed between the 96 hours CL 50 of cadmium and that of the mixture of the three metals, suggesting that cadmium modulates the toxicity of the mixture. Vanegas et al [37] and Negilsky et al [38] observed a synergism in a Cd + Zn mixture working with Penaeus setiferus (shrimp), and Callianassa australiensis (shrimp), respectively.…”

The effects of Cd, Cr, Pb and their mixtures on the growth and sensitivity of the scallop Argopecten ventricosus were analyzed in this study. Cadmium showed to be more toxic metal to juveniles (96 hour median lethal concentration (LC(50)) = 0.396 mg Cd/L), followed by lead (LC(50) = 0.830 mg Pb/L) and chromium (LC(50) = 3.430 mg Cr/L). Cadmium toxicity was 8 times higher than chromium and 2 times than lead. The most toxic combination was Cd + Cr + Pb. (LC(50) = 0.302 mg/L). Based on toxic units analyses (T.U.), a synergistic effect was observed for Cr + Pb and Cd + Cr + Pb. (T.U. = 0.374; T.U. = 0.403), and antagonic effects for Cd + Cr and Cd + Pb (T.U. = 1.26; T.U. = 1.43) respectively. The level of effect (from high to low) on the growth of A. ventricosus juveniles was: Cd > Cd + Cr + Pb > Cr > Pb. The EC(50) (metal concentration where a reduction of 50% growing rate is observed) obtained were: Cd = 0.018 mg/L, Cd + Cr + Pb = 0.104 mg/L, Cr = 0.51 mg/L and Pb = 4.21 mg/L. These results suggest that A. ventricosus juveniles are more sensitive to these metals in comparison to other juveniles from other bivalve species (e.g., A. irradians, Mytillus edulis, Crassostrea virginica).

“…For invertebrates, most studies have considered the effects of metallic combinations on crustaceans. A preliminary observation in the copepod Nitocra spinipes [41] showed synergy in acute toxicity for a mixture of cadmium and mercury, and a synergistic effect on mortality was demonstrated for combinations of copper and cadmium in the shrimp Callianassa australiensis [42]. The mortality of the white shrimp Penaeus setiferus was far greater when both cadmium and zinc were present in mixtures than when the metals were tested at their individual LC50 values [43].…”

The joint toxicity of nine binary mixtures of a metal (arsenic, copper, or cadmium) and a pesticide (carbofuran, dichlorvos, or malathion) was determined in the marine microcrustacean Tigriopus brevicornis (Müller) (Copepoda) by 96-h LC50 tests and measurement of acetylcholinesterase (AChE) inhibition. Acetylcholinesterase is used in the marine coastal environment as a biomarker to evaluate exposure to neurotoxic pollutants, including organophosphorous (OP) and carbamate (C) insecticides and most metals. A toxic unit (TU) approach was used to test the response addition model for mixtures of chemicals with different action modes. Studies of mixtures showed synergistic lethal effects in all cases (the strongest acute effects being observed in coppermalathion, cadmium-malathion, dichlorvos-malathion, and cadmium-dichlorvos combinations). At the sublethal level, the presence of the three metals tested seemed to enhance the inhibitory effects of certain OP and C insecticides.

“…In comparison, other studies have indicated no interaction (additivity) between these metals in copepods [9], amphipods [10], and decapods [11]. Still other experiments have demonstrated greater‐than‐additive effects of cadmium and zinc combinations in copepods [12] and decapods [13]. Of greatest interest to the present study, investigations with Daphnia magna have also reported varied responses to cadmium and zinc mixtures, ranging from decreased [14,15] to increased toxicity [15,16].…”

Investigations were conducted to determine acute (48-h) effects of cadmium and zinc presented individually and in combination on Ceriodaphnia dubia, Daphnia magna, Daphnia ambigua, and Daphnia pulex. Toxicity tests were conducted with single metals to determine lethal effects concentrations (lethal concentrations predicted for a given percent [x] of a population, LCx value). These were used to derive metal combinations that spanned a range of effects and included mixtures of LC15, LC50, and LC85 values calculated for each metal and species. In single-metal tests, 48-h LC50 values ranged from 0.09 to 0.9 micromol/L and 4 to 12.54 micromol/L for cadmium and zinc, respectively. For each metal, D. magna was most tolerant and showed a different pattern of response from all others as determined by slope of concentration-response curves. In the combined metal treatments, all daphnids showed a similar pattern of response when LC15 concentrations were combined. This trend continued with few exceptions when LC15 concentrations of cadmium were combined with LC50 or LC85 values for zinc. However, when this treatment was reversed (LC15, zinc + LC50 or LC85, cadmium), responses of all species except D. magna indicated less-than-additive effects. For C. dubia, a near complete reduction in toxicity was observed when the LC15 for zinc was combined with LC85 for cadmium. Multimetal tests with D. magna did not differ from additive. Collectively, these studies suggest that D. magna may not be representative of other cladocerans.
