Cadmium pollution from zinc‐smelters up to four‐fold higher than expected in western Europe in the 1980s as revealed by alpine ice
Estimates of past emission inventories suggest that toxic heavy metal pollution in Europe was highest in the mid‐1970s for lead and in the mid‐1960s for cadmium, but these previous estimates have not been compared to observations. Here, alpine ice‐cores were used to document cadmium and lead polluti...
