Interspecies sensitivity of arctic marine birds to methylmercury exposure

Mercury has been increasing in some marine birds in the Canadian Arctic over the past several decades. To evaluate the potential reproductive impact of mercury exposure, eggs of two species of arctic-breeding seabirds, the thick-billed murre and arctic tern, were dosed with graded concentrations of methylmercury and artificially incubated in the laboratory to determine species differences in sensitivity. Based on the dose-response curves, the median lethal concentrations (LC50) for thick-billed murre and arctic tern embryos were calculated. Compared with published LC50 values for other avian species, the murres and terns had a medium sensitivity to methylmercury exposure.
