Pesticides amenable to gas chromatography: Multi Residue Method 1

A multi residue method for the determination of pesticides amenable to gas chromatography in a wide variety of food items is described. The scope of the described method includes organochlorine pesticides, organophosphorous compounds, pyrethroids and nitrogen containing compounds. It updates and incorporates multi residue methods given for the separate groups of pesticides, mentioned as described in the manual 'Analytical Methods for Residues of Pesticides in Foodstuffs', 5th edition (1988), supervised by the Ministry of Welfare, Public Health and Culture and published by SDU publishers (ISBN 90 12 06172 5). This manual was edited by the Working Group 'Development and Improvement of Residue-analytical Methods', in which experts on pesticide analysis from regional laboratories of the Inspectorate for Health Protection and other Dutch Institutes participate. The method as presented in this report will be incorporated in the 6th edition (1996) of the mentioned manual. This report contains information gathered from practical experience of the members of the Working Group and reflects today practice of pesticide residue analysis in the Netherlands
