Indicators of pesticide contamination in the Balkhash-Alakol region

Abstract

Biological effectiveness of 15 pesticides against the Asiatic locust in Balkhash- Alakol breeding grounds is defined, which was 89,6-98,6%. The volume of chemical treatments against the Asiatic locust in 2010-2012 in the country amounted to 156,320 hectares. For the analysis of pesticide residues in the reeds, soil and test objects were taken samples from 5 points of the Balkhash-Alakol breeding grounds of Asiatic locust. The residual level of the detected pesticides such as hexachlorobenzene and heptachlor, HCH isomers and DDT about 0,0002-0,462 mg/kg in the environment indicates the low toxicity of these pesticides within 15-25 years after their use.
