PCDDs and PCDFs were assayed in soil samples from built-up areas near the municipal solid waste (MSW) incinerator at San Donnino (Florence, Italy). Samples were obtained by coring bare agricultural topsoil. Major agglomerations were hand-crushed and stones removed. Samples were allowed to dry up naturally. C13-PCDD and PCDF markers were added prior to extraction. Multistep extraction was carried out mechanically and with a 4:1 hexane-acetone solvent mixture. Cleanup steps included treatments with concentrated sulfuric acid and activated alumina chromatography. The final eluate was analyzed with high-resolution gas chromatography-mass spectrometry (hrGC-MS) utilizing the multiple ion detection (MID) technique. The analytical procedure allowed mean recovery yields and variation coefficients >70% and 2 (1 pg/g) for the tetrachlorosubstituted groups. Results of a quality assurance test involving two laboratories are discussed.
