ECOLOGICAL AND ANALYTICAL STUDY OF PESTICIDE CONCENTRATIONS IN THE WATER-SOIL-AIR SYSTEM IN THE TERRITORY OF THE SURKHANDARYA REGION AND THE REPUBLIC OF KARAKALPAKSTAN

This article presents the results of a study analyzing pesticide concentrations in environmental samples collected in the Surkhandarya region and the Republic of Karakalpakstan. Water, soil, and air samples were analyzed using gas chromatography and high-performance liquid chromatography. The study identified key pesticides, such as DDT and atrazine, and assessed their environmental hazards. The analysis revealed that in certain areas, DDT and atrazine concentrations exceed established standards. This situation is considered a threat to regional environmental safety, necessitating enhanced environmental monitoring and stricter controls over pesticide use.
