A method was modified and validated for the determination of dithiocarbamate pesticides in wastewaters. The developed method consists of sample pH adjustment to pH 12.2; removal of indigenous CS2 by purging in a vortex evaporator; acidification of the sample to hydrolyze dithiocarbamate pesticides to form CS2; extraction of the CS2 from the sample into hexane; and determination of the CS2 by gas chromatography using a Hall detector in the sulfur mode. The final method was applied to a wastewater obtained from a manufacturer of a dithiocarbamate in order to determine the precision and accuracy of the method. The quality of the standard used for nabam recovery studies was in question. Method detection limits (MDLs) in wastewaters may be higher due to interfering compounds.
