MARTINS, NRS et al. Lead poisoning mortality in wild passeriformes and its detection in free-range chicken eggs in Southern Minas Gerais, Brazil. Rev. Bras. Cienc. Avic. [online]. 2010, vol.12, n.3, pp. 149-152. ISSN 1516-635X. http://dx.doi.org/10.1590/S1516-635X2010000300002.
The mortality of passerines native of Southern Minas Gerais, Brazil, in August 2006 and the examination of sentinel free-range chicken eggs in August 2007 in an area surrounding a car battery lead smelter plant is described. The high levels of lead, as detected in the passerines (4.80-12.74 mg/kg) at the onset of mortality and at the follow-up sampling of the free-range chicken eggs (25.02-35.21 mg/kg in shells, 0.41-1.36 mg/kg in yolks and 0.40-0.75 mg/kg in the albumins), used as environmental sentinels, indicated the continuing lead pollution.
