摘要：

A simplified indirect method for the determination of the total content of polychlorinated organic compounds in waters, soils and plants was developed using adapted versions of molecular emission cavity analysis based on measurements of the intensity of the emission band of indium monochloride at 359.9 nm. The compounds of interest were separated from the matrix by liquid-liquid extraction. The detection limit was 0.05 ng of chlorine. The proposed technique is suitable for the evaluation of the level of contamination of some environmental samples with polychlorinated organic pesticides and other similar pollutants.
