Toxic effects of phenol on grey mullet, Mugil auratus Risso
Phenolic compounds are frequently found as contaminants in surface waters, including marine coastal waters. Phenols are generally classified as nonspecific metabolic inhibitors, and the main toxic effects are manifested on the nervous system due to the dissolution of lipids, whereas in the circulatory system phenols act as hemolysing agents of the erythrocytes. Data about sublethal effects of phenol, particularly to marine organisms are rather scarce. In several fresh water fish species exposed to phenol, the number of erythrocytes and the amount of serum proteins were decreased while lesion of gill filaments with edema and blood infiltration with degenerative changes in liver were also observed. These investigations concerned the identification of some physiological and biochemical changes in mullet blood as a consequence of exposure to phenol and some observations about the behavior and gross pathology of poisoned fish were also made.
