Glaciers are ecosystems and they host active biological communities. Despite their remoteness, glaciers act as cold condensers where high precipitation rates and cold temperatures favor the deposition of pollutants. These contaminants include a broad range of substances, including legacy pollutants, but also compounds still largely used. Some of these compounds are monitored in the environment and their effects on the ecosystems are known, in contrast others can be defined as emerging pollutants since their presence and their impact on the environment are still poorly understood (e.g. microplastics, radionuclides). This review aim to provide an overview of the studies that have investigated the effects of pollutants on the supraglacial ecosystem so far. Despite the distribution of the pollutants in glacier environments has been discussed in several studies, no review paper has summarized the current knowledge on the effects of these substances on the ecological communities living in glacier ecosystems.
冰川是生态系统，其中存在活跃的生物群落。尽管地处偏远，但冰川就像冷冷凝器，高降水率和低温有利于污染物的沉积。这些污染物包括种类广泛的物质，既有遗留污染物，也有仍在大量使用的化合物。其中一些化合物在环境中受到监测，并且已知它们对生态系统的影响，相比之下，其他一些化合物可被定义为新兴污染物，因为它们在环境中的存在及其影响仍知之甚少（例如微塑料、放射性核素）。本综述旨在概述迄今为止研究污染物对冰面以上生态系统影响的研究。尽管在多项研究中已讨论了污染物在冰川环境中的分布，但尚无综述文章总结关于这些物质对冰川生态系统中生物群落影响的现有知识。
