Tracing the Sources of PCDD/Fs and PCBs to Lake Baikal

Article Abstract:

The freshwater Lake Baikal, a UNESCO World Heritage Site, has a unique ecosystem threatened by PCB and PCDD/F contamination. Analysis of fish and soil samples show the chemicals are low in the pristine northeast area and high in the southwest industrialized area, which includes a chloralkali chemical complex.

Soil/air partitioning of semivolatile organic compounds. 2. Influence of temperature and relative humidity

Article Abstract:

Researchers from the University of Bayreuth, Germany investigated the effect of temperature and relative humidity on the partitioning of polychlorinated biphenyls and chlorobenzene between a layer of sandy loam soil and air.

Lack of an aging effect on the soil-air partitioning of polychlorinated biphenyls

Article Abstract:

Soil aging has been found to be an insignificant factor in determining soil-air partitioning of polychlorinated biphenyls (PCBs). Experiments employed a solid-phase fugacity meter to determine soil-air partitioning in two soil samples aged 392 days and about 30 years respectively. Storage whether by glass jars or by natural processes have been shown to have a short term effect on soil-air partitioning and none thereafter.
