“…The concentration of the CBs was estimated using a GC (Star 3400 CX, Varian) after sampling the volatile analytes by means of solid phase microextraction (SPME) (Pawliszyn 1997). Further details of analysis are given elsewhere (Dermietzel and Strenge 1999). An IC (Dionex 120, AS-14 column) was used to determine chloride release.…”

The potential for biodegrading of mono-, di-and trichlorobenzenes in a contaminated aquifer in Bitterfeld (Saxony-Anhalt) was tested both in the laboratory and using on-site column experiments. Under the prevailing anaerobic conditions, the reductive dechlorination of 1,4-dichlorobenzene (1,4-DCB) takes place very slowly. Under aerobic conditions the indigenous micro-organisms are able to mineralize monochlorobenzene (MCB) and 1,4-DCB. The degradation rates for the other two isomeric dichlorobenzenes and for 1,2,4-trichlorobenzene (1,2,4-TCB) under aerobic conditions are significantly lower. Indications were found that once the oxygen has been consumed, Fe(III) species can be used as alternative electron acceptors.

“…The possibility to use the SPME fibre in the headspace above a liquid solution or a solid, allows eliminating some matrix and interference effects because the fibre is not in contact with the sample 8,9 . This experimental mode has been successfully used for sampling volatile pollutants coming from different matrices such as air [10][11][12] , water 1,12-15 and soils [16][17][18] paying attention also to the static vs. dynamic sampling 19 . Matisova et al 20 proposed an empirical study on the repeatability of HS-SPME-GC measurements of VOC by comparing open cap and septum sealed vials without considering the variation of the experimental parameters such as sampling temperature and solvent effects.…”

Headspace Solid Phase Micro Extraction GC‐ECD Determination of Volatile Organic Chlorinated Hydrocarbons in Soils

et al. 2005

Soil samples were suspended in a suitable aqueous solvent and a solid phase microextraction (SPME) fibre was used to sample the headspace (HS) for five volatile chlorinated compounds (VOX). Their determination was made by GC-ECD technique in the splitless mode. Preliminary studies on the effects of methanol and of the sand/clay ratio on the fibre extraction were made. Four experimental factors, namely, extraction time, extraction temperature, pH and NaCl%, able to affect distribution of the analytes among the four different phases, were varied in suitable ranges. A multivariate approach applied to the face centred cube (FCC) experimental design, was used to try to optimise the overall sample response. The suitable set of factors found for the determination of chloroform, 1,2-dichloroethane, trichloroethylene, 1,1 ,2-trichloroethane, 1,1,2,2-tetrachloroethane, was a compromise among the relevant optimal factor sets of the single analytes. Detection limits of 0.003 ng, 0.022 ng, 0.001 ng, 0.015 ng and 0.002 ng were found respectively for the five cited analytes. The method was successfully used to determine the analyte contents in two real soils sampled in an industrial area.

SPME techniques have proven to be very useful tools in the analysis of wide VOCs in the air. In this study, we estimated VOCs in ambient and workplace air using a Tedlar ba /SPME/GC/MS system. The calibration curve was set to be linear over the range of 1-30 ppbv. The detection limits ranged from 10 pptv to 0.93 ppbv for all VOCs. Reproducibility of TO-14 target gas mixtures by SPME/GC/MS averaged at 8.8 R.S.D (%). Air toxic VOCs (hazardous air pollutants, HAPs) containing a total of forty halohydrocarbons, aromatics, and haloaro-matic carbons could be analyzed with significant accuracy, detection limit and linearity at low ppbv level. Only reactive VOCs with low molecular weight, such as chloromethane, vinylchloride, ethylchloride and 1,2-dichloroethane, yielded relatively poor results using this technique. In ambient air samples, ten VOCs were identified and quantified after external calibration. VOC concentration in ambient and workplace air ranged from 0.04 to 1.85 ppbv. The overall process was successfully applied to identify and quantify VOCs in ambient/workplace air.
