| Methodologies for the extraction and analysis of chlorinated pesticides from aquatic species are reviewed and compared. New multiresidue isolation techniques using Matrix Solid Phase Dispersion (MSPD) are presented for the extraction and subsequent gas chromatographic, electron capture detector determination of 14 chlorinated pesticides (;Compared to previous methods for the analysis of chlorinated pesticides in aquatic species the techniques and methodology presented here reduce analytical response time, solvent use, solvent waste and disposal and technician exposure. The methods presented are generic and may also prove applicable to the MSPD analysis of a wide range of environmental pollutants. These methods could form the basis for a new approach to pollutant analysis and should be considered as possible replacements for existing methodology utilized by monitoring agencies. |
