Trace metal concentrations in hairs of three bat species from an urbanized area in Germany

摘要: Metal-contaminated soils and sediments are widespread in urbanized areas due to atmospheric deposition close emission sources. These metals bio-available for organisms, e.g., insects, accumulate food chains of insectivorous mammals. Especially bats, which live urban regions ingest large amounts relative their body mass, at risk being poisoned the accumulation trace metals. To determine species-specific metal contents bats from environments, hair samples were analyzed by ICP-OES. Observed concentrations related foraging habitat, prey spectrum degree synanthropy. The species studied Pipistrellus pipistrellus, Myotis daubentonii Nyctalus noctula. P. pipistrellus showed highest lead zinc slightly higher cadmium than other two species, was its high synanthropy with habitat mostly located cities. In contrast, N. noctula displayed manganese copper. reason might be found spectrum, as feeds mainly on beetles that caught cultured areas. Trace determined M. ranged between values noctula, probably reflecting an intermediate level Positive correlations observed those Hair suitable monitoring tools study exposure can used differences levels species.
