Development of a Non-Radioactive Tracer for Use in Bioaquatic Environments
1970
Dean, Donald J.
The addition of a non-radioactive material to a river as a tracer has been considered. The basic problem is to recover a reasonable size water sample (in the order of a gallon) downstream from the point of addition and specifically identify the added tracer. One possible method suggest here includes using a gas chromatograph and a sensitive mass spectrometer for positive identification of the tracer. A specific substance, benzyl chloride, was added to the river where calculations including dilution volume, flow rate and recovery factors were estimate and recovery of some of the tracer was anticipated. Identification of the tracer, however, was inconclusive.
