摘　　要：Irgarol 1051是一种常用于船舶防污漆的杀生活性物质。为了评价船舶防污漆杀生活性物质Irgarol 1051的海洋环境风险,根据ISO 13073-1的评价原则和程序,对其进行环境危害评价、环境暴露评价和风险表征。通过对公共数据库的文献检索获取数据,从理化性质、环境行为、生态毒性3个方面评价Irgarol 1051的环境危害。采用评估因子法计算Irgarol 1051的预测无效应浓度(PNEC)。采用质量守恒法计算Irgarol 1051在海水中的释放率,通过MAMPEC v3.0模型推导上海洋山深水港的集装箱船区、码头、航道等暴露场景的预测环境浓度(PEC)。经过比较上述暴露场景的风险商值(PEC/PNEC)发现,港口的海水相风险商值大于1,Irgarol 1051的环境风险需要关注。Irgarol 1051 is a biocidally active substance commonly used in antifouling paints on the hulls of ships. This study aimed to assess the potential risks of Irgarol 1051 to the marine environment. Towards this objective, hazard assessment, exposure assessment and risk characterization were performed following the instructions of ISO 13073-1. Using previously published literature information available from public databases, we investigated physical and chemical properties, environmental behavior, and ecotoxicity of Irgarol 1051 to evaluate its environmental hazards. The predicted no-effect concentration （PNEC） of Irgarol 1051 was calculated using the approach of assessment factor. Its release rate into seawater was estimated by the mass-balance calculation method, and the predicted environment concentrations （PEC） of emission scenarios, such as the container ship harbor area, marina and shipping lane of Shanghai Yangshan Deep-water Port were derived, respectively, by using a validated computer model MAMPEC v3.0. By comparing the risk quotients, i.e., the ratio of PEC to PNEC, the substance could be assessed as ＂risk of concern＂ for seawater in the harbor area.
