According to the requirements of the "2020 Soil Environment Self-monitoring Work Plan of Key Soil Pollution Regulatory Units in Hebei Province" (Hebei Huan Soil Letter [2020] No. 327), Shexian Jindong Economic and Trade Co., Ltd. commissioned Hebei Teddy Environmental Protection Technology Co., Ltd. to carry out self-monitoring of the soil environment in 2020 on the plots to which it belongs, and compiled a self-monitoring report. The main information of the report is publicized as follows：

1. Project summary

1.Plot name: Shexian Jindong Economic and Trade Co., Ltd.

2.Plot number: 1304261260017

3.Compiled by: Hebei Teddy Environmental Protection Technology Co., Ltd.

4.Monitoring unit: Hebei Xuanying Environmental Testing Service Co., Ltd.

5.Quality control unit: The First Geological Brigade of Hebei Provincial Bureau of Mines

6.Quality Control Laboratory: Hebei Geological Experiment and Testing Center

2. Main conclusions of the report

(1) Heavy metals (arsenic, cadmium, copper, lead, mercury, nickel): Although the detection rate of heavy metals is high, the detection value is at the same level as the background point detection value, and is less than the corresponding screening value, so the risk of heavy metal pollution in this plot is small; chromium (hexavalent) was not detected in all sites, and there is no chromium (hexavalent) pollution.

(2) Volatile organic compounds (VOCs): benzene, chlorobenzene, 1,2-dichloroethane, toluene, m-, p-xylene and o-xylene were detected to varying degrees, with detection rates of 33. 33%, 26. 19%, 2. 38%, 2. 38%, 2. 38% and 2. 38%, other indicators are not detected, all detection values are less than the corresponding screening values, and the risk is low.

(3) Semi-volatile organic compounds (SVOCs): naphthalene, Benzo[a] anthracene, adenocarcinoma, Benzo[b] fluoranthrene, Benzo[k] fluoranthrene, Benzo[a] and Indo[1, 2, 3-cd] pyrene were detected to varying degrees, and the detection rate was 2. 38%, 4. 76%, 4. 76, 2. 38%, 2. 38%, 2. 38%, 2. 38%, a total of 42 groups of petroleum hydrocarbons (C10-C40) were tested, and the detection rate was 92. 86%, the detection values are less than the corresponding screening values, the risk of pollution is low, and other indicators have not been detected.

(4) Fluoride: a total of 42 groups of samples were tested, with a detection rate of 100%; phenol: a total of 42 groups of samples were tested, with a detection rate of 88. 10%; Zinc: The maximum value of zinc was detected in the topsoil of 1D02 in the zinc oxide production area, but GB36600-2018 has no relevant standard value, so it will not be evaluated for the time being.

(5) Among all sites, 1H01 has the most types of pollutants detected, mainly because this area (biphenylbiphenylether workshop) is the main production area, but the test results have not exceeded the screening value, so the protection of this area can be further strengthened.
