The content of polychlorinated biphenyls (PCBs) in the soil of coastal zone of Lake Baikal in 1997–2012 has been analyzed. Analysis of the samples taken at the same sites over the years has revealed the changes of the total PCBs content. On top of that, the PCBs concentration has been correlated with the organic carbon content in the soil, and the features of the individual congeners ratio under the different environmental conditions have been discovered.
