Seasonal input of heavy metals to Antarctic snow
Cadmium, copper, lead and zinc concentrations have been measured on a sequence of snow blocks covering 2 years’ accumulation at a site on the east coast of the Antarctic Peninsula. Careful collection and analysis techniques have ensured good data quality despite the very low concentrations, which av...
