✦ Synopsis

A multielement analytical technique of thermal neutron activation of frozen water samples has been developed and applied to the studies of natural waters. A rapid group chemical separation utilizing ion exchange resins and a precipitation step to reduce 24Na and 42K interferences, followed by ?-ray analysis of the fractions with Ge (Li) and multiparameter NaI (T1) systems, permits the simultaneous measurement of a large number of trace constituents. Samples of river water, rain water, processed sewage water and Greenland ice were analyzed for 19 trace elements -Ag, As, Br, C1, Co, Cs, Cr, Cu, Fe, Hg, K, Mn, Na, Rb, Sb, Sc, Se, U, and Zn. These data have been used in studies of trace element concentration factors in aquatic biota, precipitation scavenging processes, and environmental pollution.
