Some Nigerians treat their skin with PCB transformer oil to leave it soft and to gradually achieve a bleaching effect. Others in Honduras use PCBs as a cure against arthritis. In Sri Lanka, certain welders prefer working with PCB oils because these are cheaper than ordinary cooling oils. In several African countries, cooking oil on local markets originates from “transformer cannibalism” and contains sometimes pure Askarel or Pyralene PCB formulations. In Switzerland, the consumption of certain fishes from specific rivers was forbidden in the spring of 2010 due to PCB concentrations far above the allowed maximum levels in Europe. Recently, it has been reported that 90% of German sheep livers have concentrations of PCBs above accepted levels. High PCB concentrations originating from a transformer treatment plant have recently made vegetables inedible in a big German city. The world started tackling the PCB problem many years ago, however, the environmentally sound management and elimination of PCBs on a global scale remains a real challenge. Reliable PCB inventories are the first step in professional PCB management and will help to meet the aims and deadlines set in the Stockholm Convention and eventually rid the world of PCBs.
