Natural mercury exposure of European insectivorous bats may exceed a recognized toxicity threshold.

Popis výsledku v původním jazyce

Heavy metals are an important group of toxic substances harmful for many organisms. Of these, mercury is one of the most monitored in the environment. Several matrices are used for the monitoring of environmental load, including a range of organisms: bats, however, have only been examined rarely. Insectivorous bats are apex predators threatened by several human interventions in their natural environment, including heavy metal pollution. The aim of this study was to analyze the content of total mercury in the fur, flight membrane, and pectoral muscle of greater mouse-eared bats (Myotis myotis). Total mercury concentrations were also measured in carabid beetles from the catch locality Zastavka u Brna. Samples were obtained from 43 bat carcasses at two different localities in the Czech Republic (Zastavka u Brna, Mala Moravka). Total mercury content varied between 1.76-72.20g/g in fur, 0.04-0.14g/g in skin, and 0.05-0.20g/g in muscle. Total mercury values in the fur of some individuals from Mala Moravka exceeded the recognized toxicity limit. Furthermore, there was a significant difference (p<0.001) in content of total mercury in fur between localities, and there was a clear effect of age on concentrations in fur, skin, and muscle, the concentrations being significantly correlated (fur and skin rs=0.783, fur and muscle rs=0.716, skin and muscle rs=0.884). These findings confirm the usefulness of fur samples from living bats for biomonitoring mercury burden in the environment.
