| 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 |
