Abstract or Summary
  • A tracer method utilizing stable activable tracers (involving rare earth nuclides with short-lived t[subscript 1/2] < 1 day} activation products) for tracing fluid bound substances in fresh water is explored. Simulated laboratory studies showed these tracers (Dy and in) when chelated with diethylenetriamine2entaacetic acid a7i1W to be stable ( <20%) in natural waters for periods up to 8 days. Background studies showed the Dy and In content of natural waters and sediments to be low enough as not to interfere with these tracers. Also such tracers can be analyzed rapidly and are cost-competitive with radiotracers or fluorescent dyes. Field studies demonstrate the conservative nature of the tracers and point to the usefulness of simple anion/cation fractionation in dissolved species pollutant identification.
