Effects of combined toxicity of LAS and Cd<sup>2+</sup> on Cd accumulation and antioxidant enzyme activities in Carassius auratus
To investigate the combined toxic effects of linear alkylbenzene sulphonates (LAS) and Cd<sup>2+</sup> in Carassius auratus, Cd accumulations and the activities of superoxide dismutase (SOD) and catalase (CAT) were measured in gill, liver and muscles of C. auratus by exposure to single o...

| Summary: | To investigate the combined toxic effects of linear alkylbenzene sulphonates (LAS) and Cd<sup>2+</sup> in Carassius auratus, Cd accumulations and the activities of superoxide dismutase (SOD) and catalase (CAT) were measured in gill, liver and muscles of C. auratus by exposure to single or combinations of LAS and Cd<sup>2+</sup>. The results indicated that single Cd<sup>2+</sup> exposure induced its accumulation in all these three tissues with the sequence of liver > gill> muscles. Meanwhile, the combined effects of Cd<sup>2+</sup> and LAS exhibited a similar pattern in Cd accumulation compared with the single Cd<sup>2+</sup> exposure in the three tissues. The combination of 0.4 mg·L<sup>-1</sup> Cd<sup>2+</sup> and 5.0 mg·L<sup>-1</sup> LAS induced higher Cd concentration in liver; the combination of 2.0 mg·L<sup>-1</sup> Cd<sup>2+</sup> and all the levels of LAS induced higher Cd concentration in liver and muscles; and the combination of 2.0 mg·L<sup>-1</sup> Cd<sup>2+</sup> and 5.0 mg·L<sup>-1</sup> LAS increased higher Cd concentration in gill, as compared with the control. Single or combinations of Cd<sup>2+</sup> and LAS all influenced the activities of SOD and CAT in three tissues of C. auratus. The changes of SOD activity in liver can reflect better the toxic degree of pollutants to C. auratus. |
