The article describes the effect of wastes on the amount of heavy metals in light serozem soils. The study examined the total amount of elements nickel, lead, zinc and copper. The results show that among the heavy metals studied, the highest amount of copper is at a distance of 500 m (55 mg/kg) in the western direction of the Shurtan gas chemical complex, the maximum amount of total zinc is 98 mg/kg in the western direction at 1000 m and 1250 m in the northwest, at a distance of 1250 m, the maximum amount was 1250 m in the north-west direction (202 mg/kg of soil) and the maximum amount of the nickel was 257 mg/kg of soil at a distance of 1850 m in the north-west direction. These numbers are several times higher than the background index and allowable norms of the studied elements. The maximum amount of the element lead is 8-9 times its allowable level, and nickel is more than 3 times. Pollution was mainly recorded on the southern, southeastern, and southeastern sides of the complex.
