The application of a sequential extraction scheme provides information on the phase association of elements in a sample, such phases being described, for example, as ‘exchangeable/adsorbed’, ‘amorphous Fe/Al oxides’ and ‘soluble organics’

A ∼64-m long firn core from Devon Island (Canada) was used to investigate temporal trends of atmospheric lead pollution in the Canadian High Arctic. Lead concentration ([Pb]) in firn increased from 10 pg g -1 before the industrial revolution (1845-
