| 1 | 北极区域传统和新型POPs研究进展显示文摘北极由于独特的地理位置和自然条件,在全球气候环境变化的研究中占有举足轻重的地位。该区域常年低温,可能累积来自于中低纬度的持久性有机污染物(POPs),对简单脆弱的北极生态系统造成极大的压力。近40年来,尤其在2009年斯德哥尔摩公约新增9种POPs之后,北极地区的新型POPs引起的环境问题进一步受到科学家、政府和公众的关注。目前对传统POPs在北极的迁移转化过程的了解有限,新型POPs更是需要深入研究。通过对北极地区POPs相关研究进行归纳总结,重点阐述北极大气、水体、沉积物和生物体内传统和新型POPs的赋存水平、历史演变、生物富集以及来源,在此基础上进一步展望未来的变化趋势并提出一些亟待解决的关键问题。 | 劳齐斌 矫立萍 陈法锦 陈立奇 | 2017 | 地球科学进展2017,32,2: | 8 |
| 3 | Levels and trends of current-use pesticides(CUPs)in the arctic:An updated review,2010-2018显示文摘Global regulations and many regional and national controls restrict the use of substances that exhibit the potential for environmental persistence and long-range transport.Nevertheless,many current-use pesticides(CUPs)continue to be newly discovered in remote regions,including the Arctic.The present review serves as an update,summarizing newly available information for CUPs in the Arctic environment and biota published from 2010 to 2018.Since 2010,at least seven new CUPs have been measured in Arctic media:2-methyl-4-chlorophenoxyacetic acid(MCPA),metribuzin,pendimethalin,phosalone,quizalofop-ethyl,tefluthrin and triallate.Considering the large number of pesticides in current use,the number measured in the Arctic is very limited,however,modelling studies have identified additional CUPs as potential Arctic contaminants that have yet to be investigated in the Arctic.Owing to their recent detection,reports of CUPs in the Arctic are limited,but growing.CUPs have been reported in a wide range of abiotic Arctic matrices,including air,snow,ice,freshwater and seawater,indicating their capacity for long-range atmospheric transport,however,concentrations are generally low in comparison to legacy pesticides and other persistent organic pollutants(POPs).Recent food-web studies indicate CUPs can enter Arctic terrestrial and marine food chains,however,in contrast to POPs,the highest concentrations of many CUPs were found in lower trophic-level organisms,and the lowest concentrations detected in animals at the highest trophic levels(i.e,ringed seals,polar bear,caribou,and wolves)indicating significant trophic dilution.The detection of CUPs in the remote Arctic ecosystem reinforces the need for continued monitoring of both known and potential Arctic pollutants to prevent impacts on human and environmental health as the global arsenal of pesticides used in agriculture continuously changes. | Jennifer E.Balmer Adam D.Morris Hayley Hung Liisa Jantunen Katrin Vorkamp Frank Riget Marlene Evans Magali Houde Derek C.G.Muir | 2019 | Emerging Contaminants2019,5,1: | 0 |
