Antarctic snow record of southern hemisphere lead pollution
Lead concentrations from an Antarctic snow pit show the pattern of Pb reaching the Antarctic atmosphere over the last 70 years. Between 1920 and 1950, the Pb concentration shows significant variations around a mean of about 2.5 ng kg−1. Between 1950 and 1980, there is a clear increase to 6 ng kg−1,...
