Abstract
The effects of paper mill effluents on the prooxidant-antioxidant bala nce in the liver of bullhead were studied in fish from a contaminated river. After the low-water period (theoretical concentration of waste water 1.7%) the aryl hydrocarbon hydroxylase was strongly induced, glu cose-6-phosphate dehydrogenase, reduced glutathione and vitamin C were lower, and catalase was unaltered. Following the high-water period (t heoretical waste water concentration 0.5%), signs of oxidative stress were no longer detectable. The risks of oxidative damage due to bioche mical changes during the low-water period are discussed.
