The National Implementation Plan (NIP) under the Stockholm Convention for Romania identified PCBs as one of the top priorities requiring immediate attention and action. The PCB inventory carried out in 2004 under the NIP was based on the information obtained from the local environmental authorities. The results of the inventory were incomplete due to the fact that the data were not conveyed by all PCB owners on a voluntary basis, PCB concentration was not determined and the inventory only concerned waste electrical equipment, while equipment in use was not taken into account.
