Histopathological effects of crude oil on Atlantic cod following chronic exposure
To assess the long-term effect on the tissues of marine fish, Atlantic cod, Gadus morhua L., were exposed to water-soluble fractions of Venezuelan and Hibernia crude oils at concentrations of 50–300 ppb for 12–13 weeks in a flow-through seawater system. Histopathological changes in oil-exposed fish...
