“…The mean values for forest soil from the results of individual investigations at the respective locations are listed. The content of organic matter (e.g., 7-25%) is important for the enrichment of POPs in soils (De Maagd et al 1998). No significant differences were observed at the locations, and the pHs were found neutral (7.11-7.89).…”

“…still smaller pore size) also organochlorines (DDX, PCBs, chlorobenzenes) could be probably separated from the plant matrix with SEC. 16 individual PAHs in this difficult matrix only could be analyzed after SEC cleanup. After conventional cleanup the GC-MS analysis was impossible because of blockage of the GC column caused by high amounts of matrix components.…”

“…These lipids are comparable to many lipophilic organic pollutants (including PAHs) in terms of their physicochemical properties, e.g. solubility, molecule size [16]. The co-extraction and co-elution of plant lipids and pollutants can lead to great interference during cleanup with the overlapping between GC-MS analyte peaks and matrix peaks and consequently the faulty interpretation of analysis values.…”

One-step cleanup for PAH residue analysis in plant matrices using size-exclusion chromatography

et al. 2003

A new one-step cleanup procedure, based on size-exclusion chromatography (SEC), usable for the extracts from accelerated solvent extraction (ASE), Soxhlet extraction, or ultrasonic extraction (USE), is described. The method is suitable for the determination of polycyclic aromatic hydrocarbons (PAHs), especially from very complicated plant matrices (e.g. pine needles, deciduous leaves, mosses). The main improvement compared with previous conventional procedures is that analyte peaks barely overlap with matrix peaks in the chromatograms and that it is a very rapid and simple one-step procedure with clearly improved analytical performance. Essential advantages of this SEC procedure are the sharper GC-MS chromatograms for the PAH fraction at retention times between 9.2 and 12.0 min, distinctly separated substance peaks resulting in better analysis, shorter running times, and lower solvent consumption.

“…The TLC plates (Silica Gel 60, Merck, Darmstadt, Germany) were developed in pentane: diethyl ether (9:1 v/v). The log K ow values for the model compounds were 6.0 for BaP (De Maagd et al, 1998), 5.3 for pyrene (Helweg et al, 1997), 6.6 for TCB (Sabljic et al, 1993), and 6.6 for TBDE (Tittlemier et al, 2002). Ethanol was used as the solvent carrier for the model compounds.…”

Association of benzo[a]pyrene (BaP), pyrene, 3,3¢,4,4¢-tetrachlorobiphenyl (TCB) and 2,2¢,4,4¢-tetrabromo diphenyl ether (TBDE) with natural dissolved organic matter (DOM) was studied. The DOM samples were previously collected from natural waters at five Nordic sites during fall 1999 and spring 2000, isolated by the reverse osmosis method, and thoroughly characterized. The purpose was to determine the essential characteristics that predict the sorption capacity of DOM for hydrophobic contaminants. DOM isolates were dissolved in artificial freshwater to give a dissolved organic carbon concentration of 15 mg L -1 . Partition coefficients (K DOC ) of the model compounds between water and DOM were measured by the equilibrium dialysis method. Further, the bioavailability of BaP and pyrene to Daphnia magna Aquatic Sciences was tested in the presence of DOM with various qualities. A strong negative correlation was found for the K DOC values of BaP (R = -0.922) and pyrene (R = -0.929) with spectral absorbency ratio (A 254 /A 400 ), while the correlation (R = -0.760) was weaker for the K DOC values of TCB. The K DOC values for TCB correlated (R = 0.849) strongly with specific visible absorbency (A 600 /TOC), while the K DOC values for TBDE correlated (R = -0.739) with relative fluorescence emission. Generally, bioavailability of BaP and pyrene to D. magna reflected the measured association of the compounds with DOM. The data emphasize the importance of aromaticity of DOM, estimated by simple spectroscopic methods, in predicting sorption capacity for polycyclic aromatic hydrocarbons. The situation with halogenated compounds still remains unclear.
