Organochlorinated pesticides have a long history of widespread use and are persistent organic pollutants. Traces of these pesticides can still be found in the environment in the top layer soils after more than twenty years they have been banned. They have significant toxicity to plants, animals and humans, accumulating in food chains. It is therefore importan to rely on an accurate chromatographic separation and to obtain an exact quantification easily even in complex matrices.

EPA Method 608 is a gas chromatographic (GC) method applicable to the determination of certain organochlorinated pesticides and PCBs in municipal and industrial wastes.

EPA Method 8081 is used to determine the concentrations of various organochlorinated pesticides in extracts from solid and liquid matrices.

The requirements of both methods are achieved in the following analysis.
