Abstract

In order to grasp the soil environmental pollution risk of closed enterprises in Mentougou District, this study targeted 32 industrial enterprises in Mentougou for soil environmental pollution risk screening. Through pollution identification, field investigations, personnel interviews, drilling sampling, and analytical testing, 19 closed enterprises that met the sampling conditions were sampled and analysed, collecting a total of 132 soil samples (including 17 parallel samples). The survey results show that the pH values of the soil from various enterprises ranged between 7.10 and 8.45. Heavy metal detection indicators (arsenic, cadmium, copper, lead, mercury, nickel) in soil samples and petroleum hydrocarbons measured in individual plots did not exceed the screening value standards for the first category of land in the "Soil Environmental Quality Risk Control Standard for Construction Land Soil Pollution (Trial)" (GB 36600-2018). Overall, the soil environmental pollution risk faced by closed enterprises in Mentougou District is controllable.
