With estimations of over 500,000 tonnes in existence globally, obsolete pesticides have become a major burden on the environment. Sitting in the corners of warehouses, or buried underground, they are often stored in corroding barrels from which they seep, contaminating soil, groundwater or rivers. In Central and Eastern Europe several hundred thousand tonnes are thought to exist. Managing these is now an important environmental issue.
Jan Betlem reports.
In Central and Eastern Europe many stockpiles are a legacy from a past Soviet era. Decisions on the amount of pesticide to send to each Soviet republic were made centrally and these amounts arrived each year regardless of need, with surpluses never returned. Stockpiles gradually grew with farmers storing them as best they could, sometimes by burial.
The Stockholm Convention on Persistent Organic Pollutants (POPs) has raised awareness of the problem of obsolete stockpiles and provides guidance on the management of POPs waste. The convention aims to stop the production and use of POPs chemicals but also requires the identification and management of POPs waste1, including the nine pesticides listed2. Countries ratifying the convention are required to develop National Implementation Plans (NIPs) outlining how they will comply with their obligations under the convention. These countries are eligible to receive funding from the Global Environment Facility to develop NIPs. While not all obsolete pesticides are listed under this convention many stockpiles contain a mixture of both POPs and non-POPs pesticides. The African Stockpile Programme has recognized the importance of destroying non-POPs pesticides in stockpiles along with
POPs.

Based on data presented at the 6th and 7th International HCH and Pesticides Forum meetings. In reality stockpiles may be larger because in many countries the waste stored at certain manufacturing and distribution facilities could not be accessed.

The 6th International HCH and Pesticides Forum in Poznan, Poland, in 2001 issued the 'Poznan Declaration' outlining the problem and steps required to address it. This recognised that many governments in CEE countries lacked the technical, financial and logistical resources to tackle the problems presented by obsolete pesticides. It also recognised that addressing the situation would require a strategic and systematic approach with one of the first stages being to document the extent and location of stockpiles. The Food and Agriculture Organisation of the United Nations (FAO) has established internationally accepted guidelines for generating such 'inventories' based on work in Africa. After identification, stockpiles must be treated appropriately and strategies put in place to prevent future accumulation of
stocks.
Representatives at the UN Economic Commission for Europe's 5th Ministerial Conference 'Environment for Europe' in Kiev, 21-23 May 2003, explicitly addressed the problem. They explicitly expressed concern that stocks of obsolete pesticides are widespread and form a severe threat to human health and the environment, as they are often left under poor management and control. The CEE/NIS countries should be assisted technically and financially both through EU and EU member programmes in the execution of nation wide inventories, locating and identifying obsolete stocks, followed by prioritised disposal programmes to eliminate the acute risks for human health and the environment. The participants of the 7th International HCH and Pesticides Forum in Kiev, Ukraine (2003) recommended that an active Working Group be established to develop a Programme of Action, to enable concerted actions in collaboration with governments, appropriate international organisations, international and regional development banks, and other stakeholders, including professional and public interest organisations and
industry.
This Programme of Action should serve as a catalyst for the establishment and implementation of Programmes by the Governments of the
region.
Republic of Moldova
During the Soviet era the agricultural sector was prevalent and Moldova was used as an experimental base for research on pesticide use. Over 50,000 tonnes were imported per year during the 1980s, with around 20 kg/ha applied, higher than the world average. The centralized system for providing pesticides, generous subsidies, and the lack of strict pesticide legislation led to the accumulation of stockpiles of unused pesticides. In 1977 a special dump city was built in the south of the country near Cismichioi village and about 4,000 tonnes buried there between 1977 and 1987 including 654 tons of
DDT.
Since the end of the Soviet era pesticide use has declined dramatically with only 1 kg/ha applied in 2002. However, obsolete stockpiles remain. Official inventory data show that in 2002, 1712 tonnes of obsolete pesticides were held in 344 locations, including a number of POPS-listed pesticides (131 tonnes of toxaphene, 21.7 tonnes HCH, along with some DDT and heptachlor). In most cases the stockpiles are in bad condition with products unmarked or intermixed and packaging in poor condition.
In 2002 the State Ecological Inspection assessed over 20 of the stockpiles. At a distance of over 5 m from the stocks concentrations of organochlorine pesticides in soil were found exceeding maximum permissible concentrations (MPC) by 9 times, and at a distance of 150-200 m MPCs were exceeded by 3.5 up to 7 times. It is now urgent to ensure the environmentally safe removal of all 344 stocks of obsolete pesticides.
In 1999-2000 research was carried out on the 'dump city' of Cismichioi under the framework of the TACIS Programme. This suggest that the pesticides buried at this site have not yet leaked. However, at some point the dump is likely to depressurize allowing contents to leak. It is vital that the waste is removed before this
happens.
However, the Republic of Moldova is struggling to solve problems related to the presence of unused and prohibited pesticides stocks due to the lack of financial and technological resources. This has lead to the Government involving the Army in cleaning up the obsolete pesticides. The army has experience of dealing with hazardous chemicals and they have already collected obsolete stocks from half of the
country.
Financial support is needed from international organizations and donor-countries. Recently a Dutch NGO (Milieukontakt Oost Europa), in collaboration with national and international partners and funded through the Dutch Government, initiated a new obsolete pesticides project covering the largest rayon in Moldova. This will include inventory, repackaging, collection and centralizing obsolete pesticides combined with extensive awareness raising activities amongst NGO and Government institutions in the country. |
