The effects of near-future coastal acidification on the concentrations of Cd and Pb in the crab Dotilla fenestrata
Changes in seawater chemistry due to anthropogenic uptake of CO(2) by seawater results in a phenomenon termed ocean acidification. Ocean acidification has been predicted to substantially affect the exposure, behaviour, mobility and fate of toxicants with significant impacts on marine organisms. This...

Changes in seawater chemistry due to anthropogenic uptake of CO(2) by seawater results in a phenomenon termed ocean acidification. Ocean acidification has been predicted to substantially affect the exposure, behaviour, mobility and fate of toxicants with significant impacts on marine organisms. This study assessed the interactive effects of acidification and metal concentrations of Cd and Pb in the exoskeleton of the crab Dotilla fenestrata. Crabs were acutely exposed to varying concentrations of Cd (0.5, 0.75 and 1.00 mg/l), Pb (6.50, 8.50, and 10.50 mg/l) and Cd/Pb (4.50, 5.75 and 7.00 mg/l) and near-future pH of 7.2, 7.4 and 7.6 for 96 h and concentrations in the exoskeleton were analyzed using ICP-OES. Cadmium concentrations in the exoskeleton due to pH effects were in the order of 7.4 > 7.6 > 7.2, while concentrations in the exoskeleton exposed to pH 7.4 were significantly higher (ANOVA HSD: df 6; p < 0.01) compared to those of pH 7.2 and 7.6. Crabs exposed to varying Pb concentrations showed no common trend in Pb concentrations with varying pH. Concentrations of Cd and Pb in the exoskeleton of crabs exposed to combined Cd and Pb were significantly higher (ANOVA HSD: df 6; p < 0.01) at pH of 7.2 and 4.50 and 7.00 mg/l exposures. Crabs exposed to mixed metal concentrations showed elevated levels of Cd and Pb compared to those exposed to single metal due to their regulatory capacity when exposed to mixed metals. |
