摘要: We analyzed the spatial distribution of an antifouling biocide, 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (Sea-Nine 211) in surface water and sediments Hiroshima Bay, Japan to determine extent contamination by this biocide. A quantitative estimate environmental concentration (ECD) species sensitivity distributions (SSDs) for marine organisms were derived using a Bayesian statistical model carry out probabilistic ecological risk analysis, such as calculation expected potentially affected fraction (EPAF). The analysis supported notion that Sea-Nine 211 is used mainly treatment ship hulls Japan. calculated EPAF suggests approximately up maximum 0.45% are influenced toxicity Bay. In addition, estimation with conventional quotient method indicated was cause concern
