The soil is a
natural reservoir and a transporter component of the terrestrial ecosystem for
polychlorinated biphenyls (PCBs). The determination of PCBs is important to identify the necessary precautious steps to be
taken.
The objective of this study is to determine seasonal and regional PCB
variations in the soil in Bursa-Turkey. In this context, soil samples were
collected from 19 different points during summer and winter seasons and
analyzed by gas chromatography-electron capture detector (GC-ECD) for S82 PCB. The
regional variation of S82 PCB
concentrations was 0.03-85 ng/g dry matter (DM). The highest S82 PCB
concentration was measured sampling points near the iron-steel plant in both
seasons. At all sampling points, S82 PCB
concentrations were higher in winter than those in summer. In general,
high-chlorinated homologes groups (>6-CBs) in summer and low-chlorinated
homologes groups (<5-CBs) dominated in winter. Also, a significant
correlation was found between the heavy species (>5-CBs) and TOC, while no
significant correlation was observed between the light species (<5-CBs) and
TOC. The S7 PCB range of winter and summer
seasons is 0.043-3.87 ng/g DM and 0.02-1.97 ng/g DM, respectively. The average
Dutch S7 PCB concentration in winter was
0.735 ± 1.05 ng/g DM, while in summer it was 0.462 ± 0.72 ng/g DM.
