Abstract. As described in the article, light gray soils common around the Shurtan gas chemical complex are contaminated with mobile forms of lead and nickel. The highest content of the mobile form of lead was 55.2 mg/kg, which is located 850 m south of the complex. In the south-east and south-west directions from the complex, the soil is very heavily contaminated and fields with a mobile lead content of more than 50 mg/kg are found at a distance of 1500 meters from the complex.
It was determined that the maximum content of mobile lead is 9 times higher than the maximum permissible concentration (MPC) (6 mg/kg of soil). As studies show, the content of mobile nickel in the east direction was 28.2 mg/kg, in the south direction - 32.6 mg/kg of soil, in the west direction - 30.2 mg/kg of soil, in the north direction - 25.2 mg/kg of soil. Contamination of irrigated light gray soils widespread around the complex with nickel is similar to soil contamination with lead. The highest content of mobile nickel is noted in the southern and southeastern directions in accordance with the wind rose. The maximum content of mobile nickel is observed in the southeast direction from the complex at a distance of 1500 meters and it was 53.1 mg/kg of soil. Soil contamination with heavy metals occurs within a radius of 2000 meters from the complex in the southern, southwestern and southeastern directions.
