Progress is reported in research on the use of ammonium pyrollidine-dithiocarbomate (APDC) as a reagent for concentrating trace elements from natural waters prior to their determination by x-ray fluorescence spectrometry. Tin is among the elments to which this procedure proved applicable in Lake Michigan. Results for both surface waters and the southern basin's two major tributaries are tabulated. Although sparse, the data indicate higher Sn concentrations in late autumn river runoff than in samples taken in the spring, and higher levels in coastal samples (station 5) than those taken further offshort (stations 18 and 19). Sediment analyses indicated a sharp inrease in the Sn content in the more recent deposits. (JGB)
