Analysis of lead distribution in avian organs by LA-ICP-MS: Study of experimentally lead-exposed ducks and kites

Lead poisoning of wild birds by ingestion lead ammunition occurs worldwide. Histopathological changes in organs lead-intoxicated are widely known, and concentration each organ is measurable using mass spectrometry. However, detailed localization at the suborgan level has remained elusive lead-exposed birds. Here we investigated experimentally ducks kites laser ablation inductively coupled plasma spectrometry (LA-ICP-MS). In both kites, accumulated diffusely liver, renal cortex, brain. accumulation was restricted to red pulp spleen. With regard species differences distribution patterns, it noteworthy that intensive observed arterial walls only kites. addition, copper brain altered ducks. Thus, present study shows its between avian for first time. These findings will provide fundamental information understand cellular processes mechanisms susceptibility exposure.
