我国氯化石蜡的风险与管控:现状及展望
Risk and Control of Chlorinated Paraffins in China: Current Situation and Prospect
-
摘要: 氯化石蜡(Chlorinated paraffin,CPs)被广泛用作阻燃剂和增塑剂的添加剂,能够在生产和使用过程中释放到多种环境介质中(例如水、沉积物、灰尘、空气和土壤等)。该研究收集并深入讨论了已发表的CPs相关研究,通过释放因子解析,估算了CPs通过生成和使用向环境中的排放量,发现环境中CPs主要赋存于土壤介质中。人类活动、经济活动和经济水平等对CPs在不同区域的赋存具有重要影响。对于人群暴露的解析表明,职业暴露场景显著高于其他场景,但整体上,生态风险和人体暴露风险评估表明CPs目前对我国生态环境与人体健康的危害有限。进一步,该文介绍了国内外对于SCCPs和MCCPs的管控措施,为我国对于CPs的风险评估和管控策略提供支持,并为将来可能的CPs淘汰提供参考。基于化学品管理和风险评估的考虑,未来亟需进一步深入开展MCCPs和LCCPs的迁移转化和风险研究,特别是评估CPs管控所造成的潜在经济、社会和环境影响,以更好地为CPs产品的管控和国家开展履约行动提供重要科学数据和技术支撑。Abstract: Chlorinated paraffins (CPs) are widely used as flame retardants and plasticizers, which facilitate the release of CPs into various environmental media, such as water, sediment, dust, air, and soil. This study collects and deeply discusses the published CPs related studies. Through the analysis of release factors, we estimated the emission of CPs to the environment through generation and use, then found that CPs mainly exists in soil in different environment medias. Human activities, economic activities and economic level have an important impact on the occurrence of CPs in different regions. The analysis of population exposure shows that occupational exposure is significantly higher than others, but overall, the assessment of ecological risk and human exposure risk shows that CPs has limited harm to our ecological environment and human health. Furthermore, this paper introduces the control measures of SCCPs and MCCPs at home and abroad, which will provide supports for the risk assessment and control management of CPs in China and provide references for possible CPs elimination in the future. Based on the consideration of chemical management and risk assessment, it is urgent to further carry out the migration, transformation, and risk research of MCCPs and LCCPs in the future, especially to assess the potential economic, social, and environmental impact caused by CPs control, so as to better provide important scientific data and technical support for the control of CPs products and national implementation of the contract.
