气候波动如何影响滴滴涕和六氯环己烷在全球范围内的分布？在这项研究中，气候变化和滴滴涕和六六六在冰芯的沉积之间的相互作用，从山。珠峰（青藏高原），Mt.考察了慕士塔格（帕米尔高原东部）和落基山脉。关于滴滴涕/六氯环己烷沉积的所有数据均来自已公布的结果。滴滴涕和六氯环己烷的浓度在冰芯从山。珠峰与厄尔尼诺-南方涛动有关。滴滴涕在一个冰芯从山的浓度。Muztagata与西伯利亚高压型有显著相关。落基山脉雪穹冰芯中的六氯环己烷浓度与北大西洋涛动有关。这些联系表明，气候变化与持久性有机污染物的全球分布之间存在某种联系。
How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data regarding DDT/HCH deposition were obtained from the published results. Concentrations of DDT and HCH in an ice core from Mt. Everest were associated with the El Nino-Southern Oscillation. Concentrations of DDT in an ice core from Mt. Muztagata were significantly correlated with the Siberia High pattern. Concentrations of HCH in an ice core from Snow Dome of the Rocky Mountains responded to the North Atlantic Oscillation. These associations suggested that there are some linkages between climate variations and the global distribution of persistent organic pollutants.
