The highly sensitive and selective methods for determination of diflufenzopyr in working zone and atmospheric air, water, soil and grain corn with using reverse phase high-performance liquid chromatography with ultraviolet detection were developed. Methods based on liquid extraction of herbicide from the samples, purification of extracts of soil and grain corn from coextract substances by redistributing the system of immisible liquids, adsorption chromatography and chromatographic determination of diflufenzopyr. Thresholds of quantitative detectability of diflufenzopyr make it possible to control observation of their hygienic norms in environmental objects and working environment, grain corn.
