Abstract: In order to improve the accuracy of water pollution degree evaluation results, a quantitative evaluation method of water pollution degree based on comprehensive biomarker response index method is proposed. Firstly, the research water area is selected, and the sampling and monitoring location is arranged in combination with the actual situation. Secondly, biomarker analysis and water sample pollutant analysis were carried out. The collected data include the content data of SOD, CAT, TBARS, GSH, GSSG, GST, GPx, AChE and MTs in gills and viscera of crucian carp, as well as the content data of Pb, As, Cd, Cu and Hg heavy metals in water samples. Finally, the comprehensive marker response index is calculated for the quantitative evaluation of water pollution degree. The experimental results show that compared with the traditional evaluation methods, this method can get more accurate evaluation results, and the evaluation accuracy is always maintained at more than 90%.

Keywords: comprehensive biomarker response index method; pollution of waters; pollution degree; quantitative evaluation.
