摘要: The accumulation of heavy metals in the environment may have a wide range health effects on animals and humans. Thus, this study, concentrations arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg) blood tissues (liver kidney) Portuguese common buzzards (Buteo buteo) were determined by inductively coupled plasma-mass spectrometer (ICP-MS) order to monitor environmental pollution these elements. In general, Hg As elements which appeared highest lowest concentrations, respectively. A percentage non-detected concentration was found for Cd (94.6 %) but, turn, it only metal that detected all kidney samples. analyzed sample showed each element evaluated. Statistically, significant differences among blood, liver, samples observed (P < 0.05). liver varied significantly with age: Adults higher hepatic renal than juveniles. Blood Pb seems show an association hunting season. Although raptors are at top food chain thus potentially exposed any biomagnification processes occur web, individuals evaluated study generally had low levels tissues. However, chronic exposure verified. results presented here lend weight arguments favor continuous biomonitoring metalloids, since accumulate will pose risk both human environment.
