CHANGES IN VOLATILE COMPOUNDS IN THE COMPOSITION OF SOIL ORGANIC COMPONENTS AS A RESULT OF THE INFLUENCE OF HOUSEHOLD WASTE

Abstract

caused by the growth of the world population and increasing urbanization. The tailing dump for domestic waste in the city of Tashkent is located in the Akhangaran district of the Tashkent region. To study the change in volatile compounds in the composition of soil organic constituents as a result of the influence of household waste, soil samples were taken and analyzed in the laboratory using a spectrophotocalorimeter, and the amount of volatile compounds in soil organic matter using gas chromatography (Agilent 8890 GC da SIM, SCAN va Electron Impact (EI), ionization mode method (Agilent 5977B Series GC / MSDc). In soil samples contaminated with household waste, elevated levels of organic compounds, such as alkanes, ethers, various organic acids hazardous to human life, benzene, amides and polyamides, which are practically not present in the background soil sample taken at a distance from the landfill . An increase in the content of these organic compounds in the soil complicates the biological, chemical, physical and agrochemical processes occurring in the soil, which leads to a decrease in soil fertility.
