Epidermal papillomatosis in fish has been proposed as an indicator of environmental stress but experimental evidence of connection between contaminants and papillomatosis in fish is scarce. We studied changes in the intensity of epidermal papillomatosis and the expression of heat shock protein 70 (HSP70) in roach, Rutilus rutilus, exposed to treated pulp mill and municipal effluents. In male roach, the increase in papillomatosis intensity was higher in fish exposed to 15% than in fish exposed to 1.5% concentration of municipal effluent. No differences were observed in papillomatosis development in females, or in HSP70 expression. In all the experiments conducted, the increasing effect of effluents seemed to be more pronounced in male fish suggesting that sex-related factors affected the intensity of papillomatosis after exposure to effluents. The present results indicate that environmentally relevant concentrations of municipal effluents may be contributing to the development of papillomatosis in fish. peerReviewed
