Persistent organic pollutants in Uzbekistan
Persistent Organic Pollutants (POP’s) in Uzbekistan: 13 registered tailings and 467 sites of the former aerospace aviation sites. Some are near residential areas. Especially a lot of warehouses in the Andijan region (at least two warehouses in each district), a large one near Bukhara and a warehouse replenished to date.
Especially difficult situation with persistent organic pollutants in Uzbekistan – is in Surkhan-Darya and Bukhara regions, and Karakalpakstan. There is data on the distribution of salary – unintentional (downwind and groundwater), or – intentional (plunder). Poverty forces the use of buried pesticides
By the early 1970s, DDT was banned as a general agricultural insecticide in the Soviet Union and the United States, and was outlawed by European states over the next few years. Some reports suggest the pesticide continued to be used in parts of the Soviet Union such as Central Asia.
DDT can remain in the soil for years without breaking down, and given the large volumes used in Soviet Uzbekistan, it continues to contaminate farmland.
A scientist in Khorezm says he has data showing that soil contamination by chlorine-based pesticides is 30 times the permissible level.
In the mid-Nineties, government environmental scientists in the newly independent Uzbekistan conducted surveys which led to action to clean up the most polluted areas – chemicals were removed from cropsprayer airstrips and chemical storage facilities all over Uzbekistan, and placed in underground concrete bunkers.
However, no action was taken to decontaminate the farmland, such as taking fields out of use while the topsoil was removed.
In 1998, land in Uzbekistan was parcelled out to newly-created private farms under a leasehold arrangement rather than outright ownership. The old aerodromes were turned into farmland as well.
