Environmental analytical characteristics of gas emissions from the solid domestic waste landfills of Turkistan oblast

Abstract

The work is devoted to the study of the state of 2 urban and 22 rural landfills of Turkistan oblast (Turkestan and Otyrar districts). Based on the conducted morphological analysis of SDW, it was determined that about 50% of waste in the landfills of Turkistan and Kentau towns can be attributed to a potential source of secondary raw materials. Chemical and analytical studies have been carried out to identify the content of harmful gas components in the atmospheric air on the territory of landfills under normal conditions and under ignition of solid domestic waste (SDW). Al hazard classes’ compounds presence was detected in the composition of landfill gas. A significant part of the urban landfills’ territories in contrast to rural areas, can be attributed to the fire hazard zone. It has been determined that during fumigation or fire, the content of toxic compounds in gas emissions is higher many times than the maximum permissible concentrations both in the working area and outside the landfills. © 2019, National Academy of Sciences of the Republic of Kazakhstan.
