This research aims to investigate behavior of fluorinated POPs (persistent organic pollutants), such as PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoate, in urban water environment, and to study their countermeasures. The following results are drawn from three years research work:(1) Analytical procedure developmentIn addition to PFOS and PFOA, a measurement procedure of other several PFCs (perfiuorinated compounds) was also investigated. This work included extraction of PFCs from particulate phase and condition optimization of SPE (solid phase extraction) and LC-MS/MS.(2) PFCs distribution surveys in Japan and overseas countriesWater samples from natural areas (rivers, lakes and others), tap water, and discharge from wastewater treatment plants were collected at several sites in 14 prefectures (Japan), and 10 overseas countries. PFCs analysis of these samples shows (1) PFCs level are different in earl prefecture and country, (2) Sources of them are non-natural, especially … More from wastewater treatment plants, and (3) Their concentrations are not reduced during journeys to downstream by natural purification processes.(3) Functions of water purification plants for PFCs removalThe PFCs concentration relationship between natural waters and tap waters showed that most of water purification plants can not remove PFCs. Even in plants adopting advance treatment processes such as ozonation and GAC filtration, slight reduction was seen in GAC filter only.(4) Functions of wastewater treatment plants for PFCs removalWastewater treatment plant surveys were conducted at 14 plants in Japan, and at 10 plants in 4 overseas countries. The results thawed (1) most of PFCs can not be removed in wastewater treatment plants, (2) influent concentrations and resultant effluent concentrations are widely ranged, depending on wastewater treatment plants, and (3) activated sludge adsorbs a large amount of FPCs, resulting in high storage of PFCs in wastewater treatment plants.(5) Treatment method studyThe study in water purification plants and wastewater treatment plants showed that ordinal treatment processes hardly remove PFCs. However, some of new processes seem to be effective, such as GAC adsorption, which can remove them during a short period, and UV radiation, which can decompose FPOA with long treatment time. Less

本研究旨在调查PFOS（全氟辛烷磺酸）和PFOA（全氟辛酸盐）等氟化POPs（持久性有机污染物）在城市水环境中的行为，并研究其对策。经过三年的研究工作，得出以下结果：（1）分析程序开发除了PFOS和PFOA外，还开发了其他几种PFCs的测量程序 （全氟化化合物）也进行了研究。这项工作包括从颗粒相中提取 PFC 以及 SPE（固相萃取）和 LC-MS/MS 的条件优化。(2) 日本和海外国家的 PFC 分布调查在日本 14 个都道府县和海外 10 个县的多个地点采集了自然区域（河流、湖泊等）、自来水和废水处理厂排放的水样。 国家。对这些样品的 PFC 分析表明：(1) 伯爵府和国家的 PFC 水平不同，(2) 它们的来源是非自然的，特别是来自废水处理厂，以及 (3) 在通过自然净化过程流向下游的过程中，它们的浓度不会降低。(3) 净水厂去除 PFC 的功能天然水和自来水之间的 PFC 浓度关系表明，大多数水 净化厂无法去除 PFC。即使在采用臭氧化和GAC过滤等高级处理工艺的工厂中，仅GAC过滤器也略有减少。(4)废水处理厂去除PFC的功能对日本国内的14家工厂和海外4个国家的10家工厂进行了废水处理厂调查。结果解冻（1）废水处理厂中大部分PFCs无法去除， (2)进水浓度和最终出水浓度差异很大，具体取决于废水处理厂；(3)活性污泥吸附大量FPC，导致废水处理厂中PFCs大量储存。(5)处理方法研究净水厂和废水处理厂的研究表明，常规处理工艺很难去除PFCs。然而，一些新流程似乎 活性炭吸附可以在短时间内将其去除，而紫外线照射则可以在较长的处理时间内分解 FPOA。少
