  • 专业解析

    持久性有机污染物(Persistent Organic Pollutants,POPs) 是一类具有长期残留性、生物蓄积性、远距离迁移能力和高毒性的化学物质。这类污染物在自然环境中难以降解,可通过食物链富集,对生态系统和人类健康构成严重威胁。

    核心特性

    1. 持久性

      POPs的化学结构稳定,可在环境中存留数十年,例如二噁英的半衰期可达数十年(来源:联合国环境规划署)。

    2. 生物蓄积性

      通过食物链逐级放大浓度,例如北极熊体内检测到高浓度多氯联苯(PCBs)(来源:北极监测与评估计划)。

    3. 长距离迁移

      通过大气和海洋环流扩散至偏远地区,如南极和北极(来源:《斯德哥尔摩公约》秘书处)。

    4. 高毒性

      部分POPs具有致癌、致畸或干扰内分泌的特性,例如滴滴涕(DDT)与生殖系统疾病关联性已被多项研究证实(来源:世界卫生组织)。

    常见种类与管控

    国际社会于2001年通过《斯德哥尔摩公约》,将首批12种POPs列入管控名单,包括艾氏剂、氯丹、滴滴涕等(来源:UNEP官网)。2023年新增全氟烷基化合物(PFAS)等物质,进一步扩大管控范围(来源:美国环保署)。

    健康与环境影响

    POPs暴露可能导致癌症、免疫系统损伤及发育异常。例如,越南战争中橙剂(含二噁英)的使用导致数十万人健康受损(来源:《柳叶刀》研究报告)。当前全球仍致力于通过监测和技术创新减少POPs污染(来源:国际污染物消除网络)。

    网络扩展资料

    Persistent Organic Pollutants(POPs),中文译为持久性有机污染物,是指一类具有长期残留性、生物蓄积性、半挥发性和高毒性的人工合成或天然有机化学物质。它们对环境和人类健康具有严重危害。

    核心特性

    1. 持久性
      在环境中难以降解,可残留数十年甚至更久(如半衰期长),抵抗生物降解、光解等自然分解过程。

    2. 生物蓄积性
      具有脂溶性,易在生物脂肪组织中蓄积,并通过食物链逐级放大。例如,顶级捕食者(如人类)体内的浓度可达环境中的数万倍。

    3. 远距离迁移性
      可通过大气、水体等介质长距离迁移,甚至到达极地等偏远地区。

    4. 高毒性
      具有致癌、致畸、生殖毒性、神经毒性及内分泌干扰等危害。

    主要分类与来源

    国际管控

    2001年《斯德哥尔摩公约》将POPs列为全球管控对象,旨在减少或消除其生产和使用。目前受控物质已从最初的12种逐步扩展至数十种。

    POPs的四大特性使其成为全球性环境问题,需通过国际合作进行严格管控。更多分类和管控进展可参考《斯德哥尔摩公约》及相关研究。
