阿特拉津海水水质基准及在莱州湾的生态风险评估研究
Seawater Quality Criteria Derivation and Ecological Risk Assessment for Atrazine in Laizhou Bay
摘要
Abstract
As a widely used herbicide,atrazine is ubiquitous in coastal environments,but its marine water quality criteria are still lacking.Therefore,this study collected the toxicity data of atrazine on ma-rine organisms and obtained 76 acute toxicity data on 38 species in 10 phyla and 34 families.Among them,Tetraselmis Chuii and Bellerochea polymorpha with a species mean acute toxicity value of 0.02 mg/L were the most sensitive to atrazine.A total of 32 chronic toxicity data were obtained,including 19 species covering 10 phyla and 18 families.Navicula sp.had a species mean chronic toxicity value of 0.004 3 mg/L and was the most sensitive to atrazine.Based on the acute and chronic toxicity data,the short-term and long-term seawater quality criteria for atrazine derived by the species sensitivity distribu-tion(SSD)method were 6 600 and 1 975 ng/L,respectively.In addition,this study investigated at-razine pollution in the surface seawater of Laizhou Bay and found that its detection rate was 100％,with a concentration range of 48.15～118.24 ng/L.Both the hazard quotient method and joint probability curve method showed that the ecological risk of atrazine in Laizhou Bay was at an acceptable level.The results can provide scientific basis for establishing the seawater quality standard for atrazine and evalua-ting its ecological risk.关键词
