Sažetak
The efficiency and reproducibility of an analytical procedure for trace determination of polychlorinated biphenyls (PCBs) in soil/sediment samples were evaluated by analyses of soils differing in their sorption-controlling properties. PCBs were accumulated from soil by sonicated multiple extraction with a 1:1 acetone/n-hexane mixture. The extracts, purified by treatment with copper powder, mercury, and sulphuric acid were analyzed by gas chromatography.
The extraction efficiency from a soil spiked with 4-430 μg kg-1 of Aroclor 1242/Aroclor 1260 mixture depended on the initial PCB mass fraction. The matrix effect was evaluated by the analysis of PCBs added to five European reference soils differing in organic matter content, grain size distribution, mineral composition, pH values, and iron and aluminium oxides content. In four of these soils, a linear correlation was found between the slopes of calibration lines for the determination of PCBs and soil organic matter content. An exception was the most acidic soil with the highest, but poorly humified, organic matter. The linear regression of calibration line slopes and the content of soil fine silt particles indicated a positive, but not statistically significant, correlation.
