Abstract
The effects of exposing seawater adapted cichlid fish, tilapia (Sarotherodon
mossambicus Peters) to sublethal concentrations of toluene on the activities of lactate
dehydrogenase, succinate dehydrogenase and acetylcholinesterase were studied. The activity
of lactate dehydrogenase increased while those of succinate dehydrogenase and acetylcholinesterase
were inhibited in most tissues of the exposed fish. The alterations in the dehydrogenases
suggested that some changes in carbohydrate metabolism may have occurred.
Acetylcholinesterase inhibition in brain and other tissues indicated impairment of nervous
function in toluene-intoxicated tilapia.
