Mercury is considered to be one of the chemical elements posing the greatest threats to the health of most animals and can be transferred from aquatic ecosystems to terrestrial food webs. Many bat species forage above water, and their food sources include aquatic and amphibious organisms. Bats are very sensitive to the slightest changes in the environment. The objective was to determine the accumulation of mercury in the fur of insectivorous bats in summer habitats in an area with limited anthropogenic activity in the conditions of the middle taiga in the northwest European part of the Russian Federation. In the studied species, the average values of the metal's content (μg/g) increased in the following order: (3.294 ± 0.934), (3.909 ± 0.543), (8.011 ± 1.136), (8.366 ± 0.546), and (8.408 ± 1.386). The key factor regarding the mercury accumulation in each bat species is the foraging strategy. The mercury content in the fur of adult bats was higher than in subadults.
汞被认为是对大多数动物健康构成最大威胁的化学元素之一，并且可以从水生生态系统转移到陆地食物网。许多蝙蝠物种在水面上方觅食，其食物来源包括水生和两栖生物。蝙蝠对环境的 slightest 变化非常敏感。目的是确定在俄罗斯联邦欧洲西北部中泰加林地区人为活动有限的条件下，夏季栖息地食虫蝙蝠皮毛中汞的积累情况。在所研究的物种中，金属含量（μg/g）的平均值按以下顺序增加：（3.294 ± 0.934）、（3.909 ± 0.543）、（8.011 ± 1.136）、（8.366 ± 0.546）和（8.408 ± 1.386）。每种蝙蝠物种中汞积累的关键因素是觅食策略。成年蝙蝠皮毛中的汞含量高于亚成年蝙蝠。
