Résumé :	We analysed the levels of environmental chemicals in Eurasian Golden Plover samples from the breeding site Esterweger Dose, Lower Saxony, Germany. In total, 18 unhatched eggs and two livers of an embryo and a chick, respectively, were sampled from 2003 - 2006. Organochlorines (HCB, Sigma PCB, Sigma HCH, Sigma DDT, Sigma chlordane and nonachlor) and mercury were found in very low concentrations. Only in the liver of one embryo very high levels of DDT and metabolites were found. Compared with chemical levels in eggs of other wader species those in Eurasian Golden Plover eggs from the Esterweger Dose are assessed to be low and not critical for the reproductive success.
