We estimated the impact of seasonal and anthropogenic contaminants on antioxidant status and lipid peroxidation in common carp. The fish were reared in a power station cooling canal and in a natural pond. The examined blood parameters were: superoxide dismutase (0.91 to 5.01 U・mg⁻¹ HGB), glutathione peroxidase (3.13 to 21.03 U・mg⁻¹ HGB), bilirubin (0.44 to 1.22 mg・dl⁻¹), urea (1.66 to 6.33 mg・dl⁻¹), malondialdehyde (0.39 to 2.21 nmol・mg⁻¹ HGB), cadmium (0.031 to 0.088 mg・kg⁻¹ w.w.), and lead (0.035 to 0.131 mg・kg⁻¹ w.w.). Antioxidants were measured colorimetrically, and metals by atomic absorption. Fish living in cooling water had higher levels of all the parameters studied.
