3.3
Soil pollution risk of agricultural land
Refers to the quality and safety of edible agricultural products due to soil pollution, crop growth or soil ecological environment is adversely affected.
3.4
Soil screening values for soil contamination of agricultural pollution of agricultural soil
Land
Refers to the quality of agricultural products in the soil of agricultural land is equal to or lower than this value, for the quality and safety of agricultural products, crop growth or soil ecological environment
The risk is low and can be neglected under normal circumstances; if it exceeds this value, the quality and safety of agricultural products, crop growth or soil ecological environment may exist.
At the risk, soil environmental monitoring and coordinated monitoring of agricultural products should be strengthened. In principle, safe use measures should be taken.
3.5
Risk of agricultural soil pollution risk values for soil contamination of agricultural
Land
If the content of pollutants in the soil of agricultural land exceeds this value, the agricultural agricultural products do not meet the quality and safety standards and the risk of soil pollution in agricultural land.
High, in principle, strict control measures should be taken.

6 Use of soil pollution risk screening values and control values for agricultural land
6.1 When the content of pollutants in the soil is equal to or lower than the risk screening values specified in Tables 1 and 2, the risk of soil pollution in agricultural land is low.
Under normal circumstances, it can be ignored; when the risk screening values specified in Table 1 and Table 2 are higher, there may be soil pollution risk of agricultural land, and soil should be strengthened.
Soil environmental monitoring and coordinated monitoring of agricultural products.
6.2 When the content of cadmium, mercury, arsenic, lead and chromium in the soil is higher than the risk screening value specified in Table 1, equal to or lower than the wind specified in Table 3.
When the risk control value is concerned, there may be soil pollution risks such as edible agricultural products that do not meet the quality and safety standards. In principle, agronomic regulation should be adopted.
Safe use measures such as planting.
6.3 When the content of cadmium, mercury, arsenic, lead and chromium in the soil is higher than the risk control value specified in Table 3, the edible agricultural products do not meet the quality safety.
The risk of soil pollution in agricultural land such as full standards is high, and it is difficult to reduce the agricultural products that do not meet the quality and safety standards through safe use measures.
In principle, strict soil control measures such as prohibiting the cultivation of edible agricultural products and returning farmland to forests should be adopted.
6.4 Classification of soil environmental quality categories shall be based on this standard, combined with the results of collaborative monitoring of edible agricultural products, in accordance with relevant technical regulations
Make a demarcation.
