Objective. La Mojana is a biodiverse area of wetlands that is in the Caribbean region, being the habitat of numerous species. Mining, upstream, and agricultural activities have generated the accumulation of heavy metals in these ecosystems. Mercury (Hg) and Lead (Pb) concentrations in 47 samples of blood and feathers of Dendrocygna autumnalis (Pisingo) were determined in two sites at the Mojana, Colombia. Materials and methods. Concentrations of Hg and Pb in blood and feathers were quantified using Cold Vapor-Atomic Absorption Spectrophotometry (CVAAS) and graphite furnace atomic absorption spectrometry (GFAAS), respectively. Results. The highest concentrations of Hg and Pb in feathers and blood were 475.4±180.5 ng/g, 873.59±412.06 ng/g and...
