Enzymatic changes induced by Dibutylphthalate in Tilapia Oreochromis mossambicus


Author(s): Umamaheswari Sepperumal and Senthilnathan Saminathan

Abstract: The influx of phthalate esters into the waterways could cause adverse impact on the fauna and flora inhabiting it. Keeping this in view, the present study was designed to evaluate the risk imposed by DBP (Dibutyl phthalate), which is gauged by the changes in the enzyme (ACP, ALP, SDH) concentration of various tissues (gill, liver and muscle) of Tilapia Oreochromis mossambicus. The changes in the enzyme concentration could be an indicator of toxic stress elicited by DBP on fishes. This study reports the modulation in the enzyme concentration of gill, liver and muscle of Oreochromis mossambicus on exposure to sub-lethal concentrations of DBP (2.5 ppm and 5 ppm). ACP and SDH level of gill and liver elevated at all concentrations of DBP exposure. On the other hand, elevation in ACP concentration of muscle was evident at higher concentration of DBP (5 ppm). Statistically significant elevation in musclernSDH concentration was registered in all the DBP exposed fishes Oreochromis mossambicus. Significant elevation in ALP concentration of gill and muscle and significant decline in ALP of liver was evinced in DBP exposed Oreochromis mossambicus. These enzymatic changes of various tissues could be attributed to the mechanism by which Oreochromis mossambicus circumvents the toxic stress caused due to DBP exposure.
