| assessment of trace metals in four bird species from korea. | in birds, heavy metal concentrations are influenced by diet intake, migratory pattern, and residence time. in the present study, heavy metal concentrations (in microgram per gram dry weight) were measured in livers of four bird species from korea. iron concentrations were greater in eurasian woodcocks (scolopax rusticola) than in grey herons (ardea cinerea), little egrets (egretta garzetta), and schrenck's bitterns (ixobrychus eurhythmus). copper concentrations in grey herons were significantly ... | 2013 | 23430066 |
