DDT toxicity: gluconeogenic enzymes and non-specific phosphomonoesterases in three teleosts.

In 3 fish species (Labeo rohita, Clarias batrachus and Channa punctatus) subjected to a sublethal concentration (0.035 mg/l) of DDT continuously for 20 days both hepatic and renal acid and alkaline phosphatases were elevated, whereas the rise in glucose-6-phosphatase and fructose-1,6-diphosphatase was restricted to hepatic tissue. The variations in phosphatase levels were more pronounced in L. rohita than in the other two species.
