    abstract = {Concentrations of zinc, lead, cadmium and arsenic were determined in hepatic tissue of three groups of aquatic birds (ducks, geese and shorebirds) from a wetland irrigated with water from the wastewater treatment plant of the city of Durango, Mexico. Researchers collected liver portions from 50 birds obtained by hunters during the 2010-2011 hunting season. Metals and metalloid concentrations were determined by atomic absorption spectrophotometry. The four chemicals were detected in 100% of the samples. The results of a Kruskal-Wallis test were not significant (p&gt;0.05) among mean concentrations of Zn, Cd and As for the three groups of birds but the average concentration of Pb in geese was higher (p&lt;0.05) than in the other two bird groups. An individual of the species shoveler (<I>Anas clypeata</I>) has a maximum Cd concentration of 31.98 ppm (dry weight) and the highest value of Zn was 256 ppm (dw) that belonged to an individual of snow goose (<I>Chen caerulescens</I>). Values of metals and metalloids obtained in this study do not represent a commitment on health of birds.}
