For legacy and emerging persistent organic pollutants (POPs), surprisingly little is still known in quantitative terms about their global sources and emissions. Atmospheric transport has been identified as the key global dispersal mechanism for most legacy POPs. In contrast, transport by ocean currents may prove to be the main transport route for many polar, emerging POPs. This is linked to the POPs' intrinsic physico-chemical properties, as exemplified by the different fate of hexachlorocyclohexanes in the Arctic. Similarly, our current understanding of POPs' global transport and fate remains sketchy. The importance of organic carbon and global temperature differences have been accepted as key drivers of POPs' global distribution. However, future research will need to understand the various biogeochemical and geophysical cycles under anthropogenic pressures to be able to understand and predict the global fate of POPs accurately.
对于传统和新出现的持久性有机污染物（POPs），令人惊讶的是，在全球来源和排放的定量方面，人们所知仍然甚少。大气传输已被确定为大多数传统持久性有机污染物的关键全球扩散机制。相比之下，洋流传输可能被证明是许多极地新出现的持久性有机污染物的主要传输途径。这与持久性有机污染物的内在物理化学性质有关，北极地区六氯环己烷的不同归宿就是例证。同样，我们目前对持久性有机污染物全球传输和归宿的理解仍然很粗略。有机碳和全球温度差异的重要性已被公认为是持久性有机污染物全球分布的关键驱动因素。然而，未来的研究需要了解人为压力下的各种生物地球化学和地球物理循环，以便能够准确理解和预测持久性有机污染物的全球归宿。
