A method was developed for the determination of four compounds containing only carbon, hydrogen, and oxygen (cycloprate, kinoprene, methoprene, and resmethrin), in wastewaters. The method development program consisted of a literature review; determination of extraction efficiency for each compound from water into methylene chloride; development of a deactivated silica gel cleanup procedure; and determination of suitable gas chromatographic and analysis conditions. Extraction and cleanup procedures were developed to provide 85 percent or greater recoveries of these compounds from the wastewater. The final method was applied to Columbus POTW secondary effluent in order to determine the precision and accuracy of the method.
