This is a gas chromatographic (GC) method applicable to the determination of selected pesticides in municipal and industrial discharges as provided under 40CFR 136.1. An acidified sample is solvent extracted with ethyl ether using a separatory funnel. Esters of the acids are hydrolyzed to the free acid. The acids are esterified with diazomethane and determined by GC using an electron capture or halide detector. The compounds included in the method scope are the salts, esters, or acids of 2,4-D; 2,4-DB; 2,4,5-T; 2,4,5-TP; dalapon; dicamba; dichloroprop; dinoseb; MCPA; and MCPP.
