基于物种敏感度分布法——评价山东省某海湾除草剂扑草净的生态风险
Ecological risk assessment of herbicide prometryn in a bay of Shandong Province based on species sensitivity distribution
摘要
Abstract
With the extensive application of the herbicide prometryn in agriculture and aquaculture,coastal waters have been subjected to varying degrees of pollution.To perform the ecological risk assessment of prometryn,this study systematically examined the acute effects of prometryn on typical coastal biological groups in China,analyzed its distribution pattern in typical offshore bays based on field surveys,and evaluated its potential ecological risks using the species sensitivity distribution method.Based on the acute toxicity data of prometryn to marine organisms in China and the species sensitivity distribution method,the results of the study show that the hazardous concentration for 5％of the species and the predicted no-effect concentration of prometryn were 8.42 and 4.21 μg·L-1,respectively.From March to October 2020,the detection rate of prometryn in the surface seawater of a bay in Shandong Province was 100％,with the detection range being from 2.18 to 2.04 × 103 ng·L-1,which showed obvious seasonal variation char-acteristics and a radiative decline trend from the coast to offshore.The quotient method was used to express the eco-logical risk of prometryn in the investigated sea area,and its risk quotient(RQ)ranged from 0.001 to 0.484.Except for individual stations in March and May with an RQ of greater than＞0.1,which had moderate risk,the other stations with an RQ of less than 0.1 were considered low risk.We believe that this study can provide data reference for assess-ing the ecological risk of prometryn in the coastal marine environment of China.关键词
