| Resumen |
Conditions were determined for the collection, separation and quantitation of 4 organophosphorus pesticides that may be present in workplace air. 20L of air is drawn through a paper disc backed by polyurethane foam. The disc and foam are extracted with acetone and the extract is concentrated. A sample of the concentrate may be subjected to gas chromatography on a column of 5% Se-30 on Chromaton N-AW at 190 or 210°C (flame photometric or thermal ionisation detector), or to thin-layer chromatography on silica gel with hexane-acetone mixtures; after visualisation of spots with Dragendorff's reagent or silver nitrate, the diameters of the spots are measured. The limit detection in air of actellic, pirimiphos ethyl and pyridafenthion is 0.1mg/m3; for hostaquick, 0.2mg/m3. Error limits are 15.5-19.6%. |
