Changes in the Number of Volatile Components in the Soil Under the Influence of Household Waste

Abstract

Today, almost all large cities have a landfill for municipal solid waste, where solid waste is dumped, stored and partially disposed. Storage and disposal of household waste (mainly by burning) can negatively impact the structure, productivity indicators, and the agroecological state of the soil cover common around the landfill. Such high levels of heavy metals and metalloids in household waste ash, in turn, lead to soil contamination around the landfill. The reason is that the process of incineration and open storage of waste has a very negative impact on the environment. It should be noted that the level of heavy metal contamination of the soil around the domestic landfill is low. However, failure to fully comply with the measures for storage and disposal of waste can lead to contamination of soils around the landfill with heavy metals since the content of heavy metals in ashes is very high. Soil pollution with household waste affects all processes occurring in it and has a detrimental effect on the activity of living organisms living in the soil. In particular, soil pollution with household waste changes the amount of organic volatile compounds in the organic part of the soil. Studies have shown that benzofuran organic volatile compounds not found in background soils can be found in soils around municipal waste when exposed to pollution. Some compounds, such as carbonic acid-10.99% and di-n-desylsulfone-0.47%, which are noted in the background soils, were not found in soil sample No. 1 taken at the landfill. These compounds are removed from the soil as a result of waste incineration and other processes.
