The Pesticide Analytical Manual of the US Food and Drug Administration or the Official Methods of Analysis of AOAC International are method collections with international recognition. Both compilations are written in English, one prerequisite for its success. Method collections of EU Member States are most often available only in the national languages. Eor this reason, they are relatively unknown in other Member States. Fortunately, some good collections of official national methods are translated into the English language. The most important are...

Wheat samples should be sampled and prepared for analysis according to the general instructions provided in the Pesticide Analytical Manual , Vol. 1. Soil samples should be prepared for analysis by homogenization with a hammer mill or knife mill. Water samples are used without sample preparation.

Two steps have been added to the original Pesticide Analytical Manual method to increase the stability of the trimethylsilyl derivatives and to clean up the final extract prior to GC analysis, namely the use of a sodium sulfate mini-column to dry the extract after derivatization and the use of a Florisil Sep-Pak cartridge to remove matrix interferences. The advantages of the current method are the simultaneous evaluation of the four analytes, reproducibility and low matrix interference.

Water samples were taken on April 21, August 6, and December 11, 1980 as described and illustrated In Table I and Figure 1, respectively. All samples were analyzed for the following pesticides, using routine methods derived from the Pesticide Analytical Manual, PAM, (J ), and shown to contain less than the Indicated amounts (parts per million) captan <0.2 dlfolatan <0.1 carbaryl <0.01 methylparathlon <0.1 permethrin <0.01 azlnphosmethyl <0.1. Cited thresholds were above the detection limits.

Crop Extraction and Cleanup (FM0CC1). The extraction procedure found in the Pesticide Analytical Manual (17) was utilized throughout. In this procedure 100 g of chopped crop, 100 ml of chloroform and 200 ml of water were added to a 1 quart Mason jar and blended at medium speed for 15 min. The jar was rinsed with 2 x 20 ml of H2O and the combined contents and rinses distributed equally between three 60 mm x 120 mm polypropylene centrifuge bottles. After centrifugation at 10,000 rpm for 20 min. the aqueous layers were combined and rotary evaporated to 50 ml at which time the pH was adjusted to 1.0 with concentrated HC1.

Table 13-3, p. 141, shows a comparison of SFE (1.5 hrs), the AOAC Soxhlet method (overnight extraction), and the Pesticide Analytical Manual (PAM) method (4 hrs) for extracting fats from several fatty foods. These two tables show that SFE in 1.5 hours can extract pesticides from the most difficult samples with excellent recoveries and that fat can be removed so additional analyses can be made free of complications from fat.
