| trace element concentrations in feathers and blood of northern goshawk (accipiter gentilis) nestlings from norway and spain. | information on trace element pollution in the terrestrial environment and its biota is limited compared to the marine environment. in the present study, we collected body feathers and blood of 37 northern goshawk (accipiter gentilis) nestlings from tromsø (northern norway), trondheim (central norway), and murcia (southeastern spain) to study regional exposure, hypothesizing the potential health risks of metals and other trace elements. blood and body feathers were analyzed by a high resolution i ... | 2017 | 28688358 |
| lead in feathers and delta-aminolevulinic acid dehydratase activity in three raptor species from an unpolluted mediterranean forest (southeastern spain). | this paper presents the levels of lead found in the feathers of adult and blood of nestlings of booted eagle (hieraaetus pennatus), european buzzard ( buteo buteo), and goshawk (accipiter gentilis) sampled in the 1999 and 2000 breeding seasons in a mediterranean forest of the province of murcia (southeastern spain) located far from potential sources of metal contamination. levels of delta-aminolevulinic acid dehydratase activity (delta-alad) in blood were also measured in the nestlings. lead con ... | 2004 | 15386153 |
