THE RESPONSES OF OXIDATIVE STRESS AND SCOPE FOR GROWTH OF CORBICULA JAPONICA EXPOSED TO WASTEWATER

Present study examined oxidative stress as biochemical-level response and scope for growth (SFG) as individual-level response in brackish water clam Corbicula japonica exposed to 5× dilution municipal wastewater and its components. Dissolved matters in wastewater had influences on catalase, oxygen radical absorbance capacity and scope for growth, whereas particulate matters stimulated superoxide dismutase and scope for growth. An integrated biomarker responses index (IBR) estimating from the responses of oxidative stress makers used revealed that the most significant stressor was dissolved matters in wastewater. Further, a negative correlation was found between IBR and SFG.
