全氟和多氟烷基物质难以降解，会在环境和人体中累积，被称为"永久性化学物"。专家指出，长期大量 饮用被这类物质污染的水可能影响生殖健康和儿童生长发育，甚至引发乳腺癌、前列腺癌等疾病。 冲绳县2025年5月发布的一项调查结果显示，美军基地周边46处受检地点中，有28处水体中这类物质超 标，美军基地极有可能是污染源。其中，嘉手纳基地附近一处泉水中，这类物质的含量更是达到日本暂 行国家标准的32倍。 2016年以来，冲绳县先后四次通过日本防卫省，向美方提出进入美军基地调查污染源的申请，但一直未 获答复。2025年12月，美军终于就相关调查要求正式答复"不同意"。美方给出的理由是，暂无科学依据 证明美军基地和相关设施是污染源，且日美两国针对水体、土壤样本污染超标没有统一判定标准。 来源：@新华国际 针对驻日美军基地周边水体检测出高浓度全氟和多氟烷基物质（PFAS）污染问题，日本研究机构和民 间团体决定，2月1日起为居住在冲绳县的孕产妇提供血液检测，以防止这类"永久性化学物"影响孕产妇 和胎儿健康。部分孕产妇还可免费检测。 这项活动由"冲绳京都全氟和多氟烷基物质研究会"和一家民间团体共同发起。该研究机构说，最新研究 显示 ...
