The potential of Me tert-Bu ether, toluene and Et acetate for determining extractable organic halogens (EOX) from contaminated soil, lake sediments and sewage sludge was studied and compared with hexane, which is prescribed in the German standard method of EOX determination Soxhlet-extraction with Et acetate proved most efficient and yielded 2-6 times the EOX-values obtained by hexane. Washing of Et acetate extracts is not necessary, since interferences by coextd. inorganic halides was negligible if dried samples are extracted The detection limit is at 0.1-0.2 μg g-1 with standard deviations between 3-7%. The method was further evaluated by application onto soil samples spiked with 3-chloro-4-hydroxy-phenylacetic acid (I) and phosphoric acid-tris-(2-chloroethyl) ester (II). Et acetate recoveries were 45-52% for I and 77-110% for II, compared with 6-13% recovery by hexane. Et acetate extraction substantially improves the EOX-determination but it might still underestimate the true value. For all sewage sludge, soil and sediment samples the EOX/EOM (extractable organic matter) ratio did also increase using Et acetate. This indicates the importance of polar halogenated contaminants which are amenable by Et acetate extraction rather than by hexane. The implications of EOX/EOM ratios for EOX dynamics are discussed.
