Where are Russian PCBs.
One of the largest manufacturers of PCBs in the USSR was located in the city of Dzerzhinsk (Nizhny Novgorod region). About 145 thousand tonnes of PCBs were produced there under the brand names sovol (1939-1990), sovtol (1939-1987) and trichlorobiphenyl (TCB) (1968-1990).
the environment in Dzerzhinsk and Russia in general.
Repeatedly, PCBs were found in the soils of Dzerzhinsk. In
1995, during the World Health Organization (WHO) project to
assess the contamination of breast milk in women of
Dzerzhinsk, PCB concentrations were the highest among 5
cities of Russia - 19.65 pg TEQ / g fat.
In 2005, within the framework of the International
Project IPEP, assessment of the
contamination of food by POPs in

Nizhny Novgorod households f

Russia has stopped the production of PCBs about 20 years ago. In order to fulfil the requirements of the Stockholm Convention to remove PCBs containing equipment from use, it is necessary to understand where PCBs are located.

In 1999 there were 985 tonnes of PCBs recorded in
the Nizhny Novgorod region. However, in 2005,
when eco-SPES carried out its inventory in the
region, only 8% of these quantities (120.5 tonnes)

Dzerzhinsk PCB concentrations repeatedly
exceeded the maximum allowable levels.
In the sediments of the Volosyanikha channel
that for more than 50 years served as
the reservoir for effluent from the Dzerzhinsk
chemical plants, high concentrations of PCBs
were also found.
During the inventory it was found that environmental authorities in Russia - both regional and federal entities – lack information on the presence of PCB containing equipment and wastes, regulations related to PCBs and the environmentally sound management of PCBs. Russian environmental NGOs are concerned that the reform of state environmental agencies will result in the reduction in functions of these agencies, causing further loss of information.
