“…Recently several methods for the determination of bromoxnynil octanoate in wheat plants (Cessna, 1980), wheat products (Lawrence et al, 1980), and soils (Smith, 1980) grains, plant material, and water (Jarczyk, 1978). None of these methods, however, appears suitable for the simultaneous determination of the two compounds and their metabolites.…”

“…It is intended that the LC method described herein be integrated to some degree with LC methodologies, including sample extractions and cleanup where possible for the other four wild oat herbicides. These include barban (Lawrence et al, 1980a), bromoxynil octanoate, benzoylprop ethyl (Lawrence et al, 1980b), and asulam (Lawrence et al, 1980c). A selective screening method by thin-layer chromatography has recently been reported for photosynthesis-inhibiting herbicides such as ureas, triazines, uracils, and anilides which can detect these compounds in the picogram range (Lawrence, 1980).…”

Current extraction, derivatization and clean‐up techniques, and instrumental methods are reviewed for the analysis of herbicide residues in biota. Sampling procedures are shown to be an integral part of the methodology. Herbicide analysis is seldom based on analyte‐specific methods but is usually integrated into multiresidue methods (MRMs). Current methods generally utilize relatively small sample sizes and miniaturized apparatus to take advantage of advances in instrumental performance and detection of analytes. These methods reduce the amount of solvent used for sample preparation and help to minimize waste generation. As well as using less solvent, the resulting miniaturized methods tend to be generally cheaper, faster, and less labor‐intensive than conventional methods and, furthermore, they reduce analyst exposure to hazardous materials. Mass spectrometry (MS), interfaced with high‐resolution gas chromatography (GC), high‐performance liquid chromatography (HPLC) and capillary electrophoresis (CE), has become the detection method of choice for herbicide analysis. MS is well suited to the confirmation of target analytes and the tentative identification of unknown analytes. HPLC–mass spectrometers are becoming more widely available and less expensive. CE is a relatively new separation technique providing many advantages over traditional gas and liquid chromatography, including shorter analysis times and smaller injection volumes. There have been advances in the development of immunoassays primarily for the rapid screening for herbicide residues. These methods, once optimized, can facilitate high sample throughput at relatively low cost compared to conventional approaches. To date however, development has been limited to aqueous systems and little immunoassay work has been done for the direct determination of herbicides in biota.
