Impact/Purpose:

In order to determine if the herbicide Quinclorac (Facet) was causing damage to tomato crops in Arkansas, a method was needed to analyze air samples for Quinclorac. This overall project was a collaboration with the University of Arkansas.

Description:

Quinclorac (Facet) is a herbicide used on rice crops. Tomato farmers were concerned that aerial spraying of this herbicide was damaging their crops. The University of Arkansas initiated a study of air, soil, and plant material to see if this herbicide had entered these tomato fields. The R6 Houston laboratory was requested to provide analysis of the air samples. There were no known methods available to analyze for this compand in air samples at the time, so the laboratory initiated an investigation into the development of such a method. A method was developed using Gas Chromatography with electron capture detectors.
