Analytical provision for hygienic monitoring of picolinafen based herbicides usage

The highly sensitive and selective methods for determination of picolinafen in working zone and atmospheric air, water, soil and grain cereals 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 cereals from coextract substances using concentrating cartridges and chromatographic determination of picolinafen. Thresholds of quantitative detectability of picolinafen make it possible to control observation of their hygienic norms in environmental objects and working environment, grain cereals.
