A method was developed that allowed for the simultaneous extraction of six pesticides (three chloro-s-triazines, a substituted amide, an organic phosphate, and a benzoic acid derivative) from either sod or water samples. This rnethod utilizes two types of solid-phase extraction columns, one reverse phase, and one anion exchange column, connected in series to extract all six compounds from a single sample. After separate elution of the two columns, high pressure liquid chromatography was employed to analyze the benzoic acid derivative utilizing a C-18 column and paired Ion techniques with a detection limit of 6 {mu}g L{sup -1}. A gas chromatography equipped with a N-P detector, was used to analyze the remaining five compounds. The detectable limit for the chloro-s-triazines was 3 {mu}g L{sup -1} while the detection limit of the substituted amide was 6 {mu}g L{sup -1}. 11 refs., 1 fig., 1 tab.
