厄瓜多尔产品、物品及环境中全氟和多氟烷基物质存在情况调查速览
Snapshot Survey of the Presence of Perfluoroalkyl Substances in Products, Articles, and the Environment in Ecuador
《关于持久性有机污染物的斯德哥尔摩公约》对186个缔约方具有法律约束力(截至2023年4月)。根据该公约,除其他责任外,各国有义务报告该公约附件A、B或C中所列持久性有机污染物(POPs)的生产、进口或出口情况;向登记处提供相关信息;维护POPs清单;监测环境中POPs存在情况。在国际化学品和废物管理、生产者责任、统一报告以及遵守国家和国际法规等更广泛的背景下,厄瓜多尔在其国家实施计划中处理了新列入的全氟和多氟烷基物质(PFAS)组,并从其国内市场选取部分产品进行了PFAS分析。所分析的产品来自于最初列出的特定豁免类型清单,并且符合人们可接受的使用目的,包括消防泡沫、影像辅助材料、润滑油/去油剂、各类纸张/包装、纺织品、皮革、涂料、清洁剂、金属电镀和杀虫剂等。研究结果表明,目前已列入《斯德哥尔摩公约》的三种PFAS仅能在少数样品中测定出;其他尚未列入《斯德哥尔摩公约》的PFAS的检出频率也很低。尽管样品数量有限,但样品涵盖了广泛的基质类型,因此可以我们得出结论,一旦上述产品成为废物并受到《巴塞尔公约》的管制,则不构成处置问题。然而,核查市场上产品中是否含有PFAS预计会给发达国家和发展中国家均带来分析方面的挑战。
The Stockholm Convention on Persistent Organic Pollutants (POPs) is a legally binding instrument for 186 Parties (status: April 2023). Accordingly, among other responsibilities, countries are obliged to report the production, import, or export of the POPs listed in Annexes A, B, or C; provide information to registers; maintain inventories; and monitor the presence of POPs in the environment. In the broader context of international chemicals and waste management, producer responsibilities, harmonized reporting, and compliance with national and international regulations, Ecuador has addressed the newly listed group of perfluorinated alkyl substances (PFAS) in its national implementation plan and sent selected products from its national market for PFAS analysis. The products analyzed came from the initially listed fields of specific exemptions and acceptable purposes, including: fire-fighting foams; photographic aids; greasers/degreasers; various kinds of paper/packaging; textiles; and leather, coatings, cleaners, metal plating, and pesticides. Our results showed that the three PFAS presently listed in the Stockholm Convention could be quantified in only a few samples; additional PFAS, not yet listed in the Convention also had low detection frequencies. Although the number of samples was limited, the samples covered a large spectrum of sample matrices, making it possible to conclude that—once these products become waste and are regulated under the Basel Convention—they would not constitute a disposal problem. Nevertheless, verification of the presence of PFAS in products on the market is expected to pose an analytical challenge for both, developed and developing countries.
