Persistent organic pollutants control strategy in China 总被引:1,自引:0,他引:1
The development of Persistent Organic Pollutants(POPs) control policy in China in the context of international concerns on POPs was reviewed. The aspects of the Chinese POPs control strategies were analyzed, and compared with those of developed counterparts(e.g. US, EU, Japan). Currently, while the legal framework on POPs management, which complies with intemational guidelines has been established, it should be improved in the areas of special POPs management, risk assessment, the precautionary principle, lifecycle management and technical support capacity. The analysis of Chinese POPs policy and suggestions for strengthening the sciencebased decision making capacity are not only useful for Chinese decision-makers, but also a case study for developing wodd and make a great contribution for the global elimination of POPs to make a toxic-free future. 相似文献

持久性有机污染物的主要特征和研究进展 总被引:42,自引:9,他引:33
概述了持久性有机污染物(POPs)在环境中的主要存在类型、生态行为特征、污染效应和对环境生物体的健康危害特性及我国在该领域的主要研究进展.重点介绍了二NFDA7英类化合物的生态毒性表示法、主要处置技术与相关的检测方法等研究进展.我国POPs相关的基础研究相对滞后,要履行好POPs公约,还面临诸多需要解决的现实问题.当前开展适合我国国情的POPs物质的环境调查监测、环境安全与健康毒理学研究并建立相关的环境控制基准和评估体系十分必要. 相似文献

The Stockholm Convention on persistent organic pollutants (POPs) was adopted in 2001. This year is the 10th anniversary of
the adoption of the Convention. Until now, 22 chemicals or chemical categories have been listed as POPs in the Stockholm Convention.
The POPs Research Center was established in Tsinghua University in the same year when the Convention was adopted. In the last
ten years, much work has been done by Chinese researchers to understand the environmental risk of POPs in China. This article
aims to review the recent research progress of our POPs Research Center and some other Chinese researchers’ studies in addressing
the environmental risk of POPs, including the priority screening and inventory study of POPs, monitoring and modeling of POPs
pollution and exposure, and environmental risk assessment and modeling of POPs. Although great advances in addressing the
environmental risk of POPs have been made in recent years, we are still facing quite a few problems, such as data scarcity
and uncertainty in environmental risk assessment of POPs. The study on the effect of POPs mixtures is in its infancy and currently
POPs are usually assessed from legal perspective by risk assessment of single chemicals. These problems should be well addressed
by further efforts. Further studies should also be taken in future to study environment risk of POPs by considering aspects
of coupled dynamics between climate processes and POPs. Such sound scientific, riskbased information can support decision-making
aiming to effectively minimize the risk level of POPs. 相似文献

我国POPs污染场地的环境管理基础与完善对策研究 总被引:1,自引:0,他引:1
固体废物不恰当处理处置是造成场地污染的原因之一,也是今后需要引起关注的环境问题.在POPs公约中,POPs污染场地和POPs废物一样有着明确的无害化管理要求,作为该公约的缔约国,我国将认真履行公约的义务,消除POPs引起的污染.根据调查,我国POPs引起的场地污染比较严重,现有的环境管理法律法规、标准和制度政策是POPs污染场地管理的基础,但这种基础还比较薄弱,尚不能完全满足环境无害化管理的要求.因此,我们在充分利用现有环境管理体系的基础上,还应该继续改进和完善现有法规和标准体系,建立相关的环境风险评价程序和资金筹集机制,加强污染场地环境管理和监督管理能力建设. 相似文献

我国持久性有机污染物污染事故预警指标体系构建 总被引:1,自引:0,他引:1
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. 相似文献
