Summary of Research-Fluorescent Tracers and Pesticides

摘要

A study was conducted to determine whether the patch test technique adequately represents the exposure experienced by a pesticide applicator, whether this test adequately applies to exposures beneath clothing, and if the patch test is adequate to deal with hand, face, and neck exposures. Findings suggested that the patch test is inadequate due to inhomogeneous exposure. The second aim of the research was to develop a fluorescent tracer system which would be both a quantitative and qualitative measuring device for determining exposure levels. 4-Methyl-7-diethylaminocoumarin was used as a fluorescent tracer in field studies. A video imaging system was then developed. The system performed well in the field. Limits of the system involved the tracer and its stability in the environment and transport to and through clothing in comparison to that of the pesticide.
