Potential Ecotoxicological Significance of Elevated Concentrations of Strontium in Eggshells of Passerine Birds


We investigated the occurrence and potential ecotoxicological significance of elevated concentrations of strontium (Sr) in eggshells of nine passerine birds from four regions in Arizona. Concentrations of Sr in eggshells ranged from 70 to 1360 mg g dry weight (overall mean 5 684 6 345 SD mg g dw) for the four regions. 23% of the eggshells had Sr… (More)
