危险化学品泄漏入海区域风险评估方法研究

我国的危险化学品区域风险评估研究工作起步较晚,针对危险化学品泄漏入海的方法研究较少。现有区域风险评估方法中评估对象多为单一风险因素,存在着未全面考虑研究区域内其他风险源和敏感资源等综合影响的不足。在结合国内外研究进展现状的基础上,强化与相关技术方法的衔接,建立了综合考虑危险化学品危险性和区域风险承受力等因素的危险化学品泄漏入海区域风险评估方法工作,并选择天津市XX企业开展方法案例应用。本研究能够为科学合理划分危险化学品泄漏区域海洋环境风险等级提供技术支撑,为开展危险化学品泄漏入海风险防范和修复评估等工作提供决策依据。

Study on Risk Assessment Methods of Hazardous Chemicals Leaking into Seas

In China, studies on regional risk assessment of hazardous chemicals have been carried out for only few years, and there are only few studies on hazardous chemicals leaking into seas. For previous regional risk assessment methods, one single risk factor is considered for most assessment targets, while comprehensive considerations of risk sources and sensitive resources for a study area are not sufficiently included. Based on previous studies, this study established a regional risk assessment method for hazardous chemicals leaking into seas. This method considered hazards of hazardous chemicals and tolerance ability of regional environment, by means of a case study of XX company in Tianjin. This method can provide technical supports for scientifically assessing marine environmental risk levels for hazardous chemicals leakage areas, and support decision-making for carrying out risk prevention and restoration assessment of hazardous chemicals leaking into seas.
