摘要
短绒飞尘无处不在,甚至在公海上空和偏远地区的尘埃沉积中也能找到。特别是较短和较细的纤维,它们可以进行长距离传输,并像沙漠中的灰尘一样在全球传播。近期,关于农村地区环境空气和沉积物中短绒飞尘的研究表明:粗略估计,合成纤维的沉积率为1~5 kg/(km2·a)。这些结果证实了一个假设,即与污水处理厂的排放相比,海洋环境中的短绒数量与空气路径更相关,这种短绒的长距离飞行输送导致了它们在北极冰等极度偏远地区也会大量存在。
Fiber fly is ubiquitous and can be found in the ambient air even over the open ocean and in dust depositions from remote areas.Particularly shorter and thinner fibers are considered to be subject to long-range transport and to travel like the desert dust around the globe.Few recently published studies examining fiber fly in the ambient airand in deposits already allow a rough estimate for rural areas:deposition rates of 1~5 kg synthetic fibers per km 2 and year can be estimated.These results confirm the assumption that the air path is more relevant for the abundance of fibers in the marine environment than the emission from sewage treatment plants,and that long-range transport of textile fiber fly is responsible e.g.for their abundance in absolutely remote areas as the arctic ice.
