环境中氟污染与人体氟效应

Fluorine Pollution in the Environment and Human Fluoride Effect

氟是人体必需的微量元素之一,具有双阈值效应。人体长期暴露于氟地球化学异常或人为活动引起的氟污染环境中,会促使氟不断进入体内,最终导致氟中毒及其它氟效应。本文介绍了近年来氟化物和全氟化合物(PFCs)在环境介质(大气、水体和土壤)中的污染状况,综述了氟污染的自然来源和人为来源及污染/转移途径;回顾了氟化物及PFCs在人体内已产生的众多效应研究;总结了在饮水型氟污染、燃煤型氟污染、工业氟污染及人体氟效应研究中存在的问题,并提出了关于氟中毒区污染、人类活动氟污染以及氟与人体健康关系三个方面的一些对策与建议。

Fluoride,which has the double threshold effect,is anecessarytrace element of human. The long-term exposureto the fluoridecontaminated environment may cause continuous ingest of fluoride intothe human body,eventually cause fluorosis and other fluorine effects. This paper described the current pollution status of fluoride and perfluorinated compounds( PFCs) in environmental media like atmosphere,water and soil,briefly described the natural sources of the fluorine pollution and their transfer pathways,reviewed effects of fluoride and PFCs in the human body,summarized problems of drinking water type,coal-burning type and industrial type fluorine pollutions,and discussed fluoride effects to human. This paper also put forwardsome suggestionsand strategies regarding fluorine pollution area,man-made fluorine pollution as well as the relationship between fluorine pollution and human health.
