Trace Elements in Frobisher Bay Rainwater

Аннотация

Using short-decay instrumental neutron activation analysis, concentrations of the trace elements Al, Br, Ca, Cl, Cu, I, Mg, Mn, Na, and V were determined in rainfall sampled from Frobisher Bay, N.W.T., during three weeks in the summer of 1984. Detectable concentrations were reported for all ten elements. Enrichment factors revealed that concentrations generally represent either crustal or oceanic natural background levels.

Key words: trace elements, precipitation, Arctic, Frobisher Bay
