heavy metal bioaccumulation in two passerines with differing migration strategies. | various anthropogenic activities have resulted in concentration of heavy metals and contamination of surrounding environments. historically, heavy metal contamination at the savannah river site (srs) in south carolina has resulted from accidental releases of stored waste generated from nuclear weapon production in the early 1950s. songbirds inhabiting and using resources from these areas have the potential to bioaccumulate metals but there is limited information on metal concentration levels in ... | 2017 | 28292671 |
