Abstract
In this study, the toxicity of cadmium-contaminated clay to the zebrafish Danio rerio was evaluated. Kaolin clay was spiked with CdCl2(1.28 mg Cd/g clay) and adult zebrafish were exposed to 0, 500, 1,000, and 2,000 mg/L Cd-contaminated clay in a continuous recirculation system. Cumulative mortality was evaluated as a function of exposure time, and LT50 values were calculated. Results of acute toxicity tests showed that an exposure to 1,000 mg/L Cd-contaminated clay resulted in LT50 values of 12 and 92 h (n = 2 experiments) and in a LT50 value of 22 h in both experiments with 2,000 mg/L Cd-contaminated clay. Positive control experiments with corresponding measured dissolved Cd concentrations were performed to evaluate by comparison the toxicity of the clay-bound Cd. These control experiments gave LT50 values higher than 144 h for both conditions. Moreover, no toxicity (LT50 > 144 h) of 2,000 mg/L uncontaminated clay was observed. This study showed that cadmium present on clay particles can be bioavailable and exert a toxic effect to the zebrafish D. rerio.
