“…To investigate the effect of Abate on small stream ecosystems, a simple and rapid method for the determination of Abate in water was necessary. Abate in water is usually determined by an extraction procedure followed by concentration of the extract and gas chromatography (3,4), or thin-layer chromatography (5), or high speed liquid chromatography (6). These methods are relatively time-consuming and tedious, and moreover large volumes of samples are needed (100-1000 mL).…”
