POPs in Belarus
period 1971-1978 more than 3,700 tonnes of pesticides were disposed of in seven
repositories located in Brest Oblast (Gershony village), Vitebsk Oblast
(Verkhnedvinskoye, Postavskoye, Gorodokskoye respositories), Gomel Oblast (Petrikovskoye
repository), Grodno Oblast (Slonimskoye repository) and Mogilev Oblast
(Dribinskoye repository). Since these repositories posed a serious threat to
the environment, in 1988 at the initiative of the Ministry of Natural Resources
and Environment it was decided to ban pesticide disposal. It is noteworthy that
the state of pesticides in underground repositories requires constant
monitoring due to the increased risk of their migration to the environment.
In 2007, pursuant
to the National Plan on Implementation of Obligations undertaken by the
Republic of Belarus under the Stockholm Convention on Persistent Organic
Pollutants for the period 2007-2010 and up to 2028 adopted by Presidential
Decree #271 of 12 June 2007, Brest repository of obsolete pesticides (Gershony
village) was eliminated. The recovered obsolete pesticides were repacked and
transferred into ecologically sound storage.
40% (or 2,824.8 tonnes) of the total amount of obsolete pesticides are kept in
six repositories. Three of them are located in Vitebsk Oblast (Verkhnedvinskoye,
Postavskoye, Gorodokskoye). There is one repository in Gomel Oblast
(Petrikovskoye), Grodno Oblast (Slonimskoye) and Mogilev Oblast (Dribinskoye).
The Verkhnedvinskoye repository of pesticides is located to the northwest
of Verkhnedvinsk District, 8 km northwest of the Belarusian-Latvian border. The
site consists of four 1-meter deep trenches with the total capacity of about
600 cubic meters. It contains 454.5 tonnes of pesticides of 47 types, some of
them are POPs.
The Gorodokskoye repository of pesticides is located 10 km northeast
of the Belarusian-Russian border and 36 km from Gorodok. The data about the
composition of the pesticide repository has not survived. According to the
ecological certificate of 1990 the only available data is the total weight (411.4
tonnes), hazard class (1st class - 43,628 tonnes; 3rdclass - 130,146 tonnes; 4th class - 237,695 tonnes). The prevailing number
of them (58%) are low-hazard pesticides. High-hazard pesticides account for
10%. By analogy with other repositories it can be suggested that about half of
pesticides of Gorodokskoye repository are organochloride. The rest are organophosphorous,
simazine triazine and inorganic compounds.
The Postavskoye repository was built in 1971 and is located in
the southern part of Postavy District of Vitebsk Oblast. The data about the
repository of hazardous pesticides has not survived. According to the
ecological certificate, the total weight of chemicals is 99 tonnes, of them 16.3
tonnes are classified as 2nd hazard class, 33 tonnes as 3rdclass and 49,7 tonnes as 4th class. By analogy with other
repositories we can assume that they have the same composition.
The Petrikovskoye repository of obsolete pesticides is the
biggest repository on the territory of Belarus. It is located in the northern
part of Petrikov District of Gomel Oblast, 42 km northeast of Petrikov, regional
centre. The repository is within the jurisdiction of the inspection of natural
resources and environmental protection of Oktiabr District. The site is located
in Koshevichi forestry and occupies 0.6 hectares. In 1974-1988 as many as 1,423.3
tonnes of obsolete and banned pesticides were buried there.
Slonim District of Grodno Oblast has one of the biggest repositories
of obsolete pesticides. According to the data of the Ministry of Agriculture
and Foodstuffs it contains 882 tonnes of pesticides, including 447.2 tonnes of
DDT (74.3%) and 1.8 tonnes of hexachlorocyclohexane (HCH). However, during the
elimination of the repository it was discovered that the amount of obsolete
pesticides had been greatly underestimated. The Slonimskoye repository was
built in 1974. The design and construction documents have not survived. It is
unknown if any engineering study (field survey and engineering-geological
study) was made therefore it is impossible to accurately evaluate the level of protection of pesticides from being
released into the atmosphere which is crucial for their dissolution and
migration to the underground hydrosphere.
Dribinskoye repository of pesticides is located in the eastern part of Dribin
District, 11 km to southeast of Dribino, regional center. It was built in three stages:in 1974, 1983 and 1988. According to the Ministry of Agriculture and
Foodstuffs of the Republic of Belarus the total weight of pesticides is
estimated at 541 tonnes, however, during the study conducted by the Central
Research and Development Institute of Water Management only 353,737 tonnes of
pesticides were identified, of them
98.74 tonnes DDT.
2008-2009 Gomel Oblast took measures to eliminate Petrikovskoye repository of
is underway to eliminate Slonim repository of obsolete pesticides. As of 18
October 2011, the recovery of pesticides from the biggest trench at the Slonim
repository of obsolete pesticides had been completed (there are two trenches
and one concrete bunker at the site). A total of 950 tonnes of pesticides was
recovered and repacked. They are being transported to Germany for ecologically

In order to
ensure implementation of the obligations undertaken by the Republic of Belarus
under the Stockholm Convention and in line with the environmental monitoring
about 150 potential sources of POPs were pretested (obsolete pesticides
repositories, household and industrial landfills, sludge lagoons, sewage fields,
etc) with 250 samples taken and 3,500 analyses made annually. This allowed
launching systematic monitoring of chlorine-containing pesticides and PCB near
the biggest and potentially dangerous sources of POPs release.

no chlorine-containing pesticides in surface and underground waters, except for
heptachlor found in some samples of underground waters located in close
vicinity to Postavskoye, Dribinskoye and Petrikovskoye repositories. The
heptachlor concentration accounted for thousands of the maximum permissible
The monitoring of farmlands and soil near stockpiles
of obsolete pesticides revealed pesticides identified as POPs (DDT, dieldrin
and endrin) in 30% and 24% of samples respectively.
The DDT concentration in farmlands did not exceed 0.03-0.06 of MPC. The dieldrin and endrin concentration found in two samples was even lower than that of DDT.
DDT was found in 24% of soil samples from
stockpiles of obsolete pesticides (ranging between 10 and 50 microgram per kilo
of soil with 0.01-0.05 MPC), in some soil samples endrin and eldrin were
detected (1-10 mcg/kg).

According to 2010 inventory, there are 7,300
tonnes of obsolete pesticides in Belarus. About 2,832 tonnes are stockpiled in
agricultural companies; 2,824.706 tonnes are buried. About 95% of obsolete
pesticides kept at agricultural companies were repacked.
Pesticides listed as POPs, undetermined
mixtures and unidentified liquids are mainly held at warehouses of agricultural
companies subordinate to Belagroservis, collective and state farms, greenhouse
compounds, agricultural cooperatives. There are no obsolete pesticides
identified as POPs nor unidentified mixtures and liquids in Gomel Oblast as in
1999-2004 the oblast plant protection center collected and transported them to
the only company specializing in recycling and disposal of hazardous and toxic
industrial waste in Belarus – Compound for recycling and disposal of toxic
industrial waste of Gomel oblast”.
Analysis of the data provided at the request of
the Ministry of Nature as well as visual inspection of stockpiles of obsolete
pesticides showed that the state of warehouse is predominately satisfactory
(92%). Every warehouse has a responsible officer assigned from the administrative
staff of the agricultural company and the majority of warehouses has in-house
security. Nonetheless, obsolete pesticides, including POPs, are not kept in
proper conditions that meet modern environmental standards (repacked and not
packed pesticides are kept together, containers are not destroyed after use).
Today the repackaging of obsolete pesticide stocks is almost completed.
whole according to the monitoring the situation with POPs concentration in the
environment in Belarus can be called satisfactory – these substances are found
only in some samples from places of stockpiling and disposal of obsolete
pesticides. Their concentrations do not exceed permitted levels.
