An«riyt)e«t Precodure for Postjeldes^CBe In Seii Extracfion Procedure

The soil samples were extracted by Ute Soxhlet method. A thirty gnim aliquot was spiked with a surrogate soluKon eonsistins of tetmchloro-m-xylene and dccficldorobiphenyl, mixed with .10 g anhydrous eodinm sulfate and eoctncied for 16 hours with 300 niL of hcxane/iicetone (1:1). Tito c.xhact was concentrated to SmL. Gbs Chropnatographio Analysis

The c.xtmct was analyzed for pcsiicidc/PCas using sixnuiUneoiiB dual column injections. The analysis was done on an HF rtgpo GC/eCD system equipped wltlt an HP S8do tiutomatlc sampler. The systems wore eontroned with an HF'ChemStation. The followng conditions wore employed; Firet Column DB-r.OR, .50 meter, 0.32 jltiti fused silicn ostpillary, 11.50 mnfllm thickness Second Cohinu) Rls-ClPesticides, 30 meter, 0.32 inm fiiiscd silica capiliarv, 0.50 tun film Uucknes-s Injector Tempennure 200-C Detector Tempcmiwrc .W’C

Temperature Progrom I2O"C for 1 minute O'-'C/roiii to 2»5'“C, Itold for 10 minutes InjecUon Voluirie 1 pL

The ges chroiStHiographs ware caUbratod using S pesticide standards at 20. SU, 100. 200, and 500 ue<b. The results front each mixture were used to calculate Uic response factor (RF, of each analyte and the average RF was used in ealculate die cuncuntration of pesticide in the sjample. QuHntiffcation was based on i he column (sigtiol i ) and the identity of the analyte was cenfirtned using the Rtx-CLPcsticidos column (signa) 2). A fingerprinT chromatogram was run using each of the seven Aroclor nuxiiiTcs and toxaphane; the calibration curves were run only if o particular PCB or toxaphene wore found in the sample.
