Transport of PCBs with leachate water from the contaminated soil

The soil was excavated from the area around the damaged capacitor of an electrical transformer station in Zadar, Croatia, and a phytoremediation experimental field was constructed with lysimeters. The levels of PCBs in the leached water samples were measured nearly three years. The experiment were conducted under the natural climatic conditions, through the hot summers and mild winters. Although the amounts of leached PCBs from the polluted soil were relatively small, their concentrations in leached water samples from 1500 to 29000 ng L-1 substantially exceeds the maximal allowed concentration of the total PCBs in the fishponds of Croatia (1 ng L-1).
