[Studies for the assessment of the herbicide prometryne in the air].
An analytical method for the quantitative determination of the triazine herbicide prometryne in air is described. In the sample preparation procedure developed, the ambient air is drawn through the adsorber tube packed with the prepurified crosslinked polystyrene resin Wofatit EP 61 (0.2-0.5 mm) for collecting the pesticide with a high efficiency. A special modified cellulose filter is of use to sample particulate matter. The trapped vapours and aerosol are nearly quantitatively eluted from the sorbent by diethyl ether and then analyzed by gas chromatography. A greenhouse experiment yielded prometryne concentrations in air up to 146 ng.m-3 after spraying on soil. The described procedure permits the measurement of airborne prometryne at trace levels up to 1 ng.m-3.
