中文摘要：

面对严峻的持久性有机污染物(persistent organic pollutants,POPs)环境污染问题,以及不断提升的化学品风险管理要求,我国对于POPs污染事故预警管理的需求日益迫切.基于生命周期理论及POPs生成机制,针对不同的POPs和污染事故的种类,构建出POPs污染事故的预警指标体系,以期为完善我国POPs污染事故预警管理提供决策支持.预警指标体系主要包括两部分:POPs预警指标和运行保障机制.POPs预警指标包括了警源指标、警兆指标和警度指标.为保障预警体系的有效实施,构建了预警响应机制及政策保障机制,包括对风险源的动态清单管理和定期评估,及时有效的警情上报,各部门的协调合作等.

英文摘要：

Early warning of pollution incidents caused by persistent organic pollutants ( POPs) is urgently needed for China in the circumstances of serious POPs pollution and in increasing demand for improvement in chemical risk management. Given different categories of POPs and pollution incidents, the index system for early warning of POPs pollution accidents was built based on lifecycle theory and POPs formation mechanisms. It will be helpful for decision makers to enhance the early warning management of POPs pollution incidents in China. The index system for early warning includes two parts, early warning and mechanism for system operation. The indices include risk source indicators, warning indicators and warning level indicators. To ensure the effective implementation of this system, the mechanisms for response and policy guarantee were also formulated. These mechanisms contain dynamic inventory management and periodical assessment of risk sources, timely and effective report of warning conditions, as well as coordination and cooperation among the relevant departments.
