A study of some environmental biomarkers in fresh water clam (Unio tigridis) and fresh water crab (Sesarma boulengeri) in Hilla river

Abstract

This study was designed to study some environmental biochemical markers such as ( MT ,GPx , CAT, AchE, ROS, SOD, Cytochrome p 450) in two species of freshwater organisms ( Clam :Unio tigrids and Crab: Sesarma boulengeri) which were collected during the study period (October 2014 to March 2015) from three sites in Hilla river, the concentration of above enzymes showed fast response of two species according to the water quality parameters fluctuation which effected by pollutants in study area .The species Sesarma boulengeri has recorded more response to the changing in water quality than another species. This study indicates that the biochemical markers different in response in aquatic organism according to water quality parameters fluctuation affected by pollution.
