Abstract
Commercial grade diesel oil was used as a source of petroleum hydrocarbon to study
the toxic effect of petroleum hydrocarbons on physiological and biochemical parameters in
an estuarine bivalve, Pnpliin malabarica. The results of the investigation revealed the adverse
effect of diesel oil on the growth condition index and biochemical constituents. The growth
was affected resulting in reduction of about 30% in the average growth rate after 30 davs.
The impact was more with higher concentration. There was reduction in the values of organic
carbon and nitrogen. The biochemical constituents such as protein and carbohydrate also
showed slight decline while the lipid content increased marginally. The results suggest that
exposure to petroleum hydrocarbon may be deleterious to manv marine and estuarine
organisms and may change the physiological and biochemical processes, depending on its
bioavailability and exposure concentration.
