Abstract:We examined the exposure of White-throated Dippers (Cinclus cinclus) to aluminum and mercury in acidified and nonacidified streams in two regions of Norway. Both metals showed significantly higher concentrations in the body tissues of dippers in acidified streams at southern sites compared to non-acidified streams in central Norway. Elevated concentrations of aluminum in acidified areas could not be explained by a corresponding elevated level of aluminum in the invertebrate foods of dippers. During our study p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
