In Japan, collected PCBs have been kept by manufacturers or sellers. Due to the big concerns for the risk at accident, however, proper treatment of PCBs is seriously required. This report reviewed international trends of PCB management, summarizing PCB treatment technologies and environmental behaviors. It was mainly based on reports at the "International Seminar on PCB Management", which was held in December, 1996, and comparatively discussed the present PCB management in Japan and those in other countries, Although the concentration of PCBs defining PCB products differed with the country or the area, many countries drew the line at 50 ppm, and the lowest one was 2 ppm. Every country has established regulations for PCB management, and now it is required to manage and open the inventory of stored PCBs and to regulate the methods of their safekeeping and treatment. Europe and US have taken action on early disposal of PCBs in more earnest than Japan. That is mainly because they have been focused on the risk of PCB accidents including PCB firing and leakage in transit. Recently chemical treatment techniques have developed and discussed, and are now almost practical besides incineration treatment.
