Editing Polychlorinated biphenyl (section)

===Slovenia===
Between 1962 and 1983, the [[Iskra (company)|Iskra Kondenzatorji]] company in [[Semič]] ([[White Carniola]], Southeast [[Slovenia]]) manufactured [[capacitor]]s using PCBs. Due to the wastewater and improperly disposed waste products, the area (including the [[Krupa (Lahinja)|Krupa]] and [[Lahinja]] rivers) became highly contaminated with PCBs. The pollution was discovered in 1983, when the Krupa river was meant to become a water supply source. The area was sanitized then, but the soil and water are still highly polluted. Traces of PCBs were found in food (eggs, cow milk, walnuts) and Krupa is still the most PCB-polluted river in the world.
