This Standard specifies the risk screening values and control values for soil contamination of agricultural land, as well as the monitoring, implementation and supervision requirements. This Standard was released for the first time in 1995.This is the first revision. The main content of this revision. ---The title of the Standard was adjusted from Environmental Quality Standard for Soils to Soil Environmental Quality - Risk Control Standard for Soil Contamination of Agricultural Land (on trial); ---Normative References is updated; terms and definitions are added to the Standard; ---The risk screening values for basic items, such as. cadmium, mercury, arsenic, lead, chromium, copper, nickel and zinc, as well as other items, such as. benzene hexachloride (BHC), dichlorodiphenyl trichloroethane (DDT) and benzo[a]pyrene in the soil of agricultural land are specified; ---The risk intervention values for cadmium, mercury, arsenic, lead and chromium in the soil of agricultural land are specified; ---The monitoring, implementation and supervision requirements are updated. Since the date of implementation of this Standard, Environmental Quality Standard for Soils (GB 15618-1995) shall be abolished. This Standard was formulated by the Department of Soil Environment Management and the Department of Science and Technology Standards of the Ministry of Ecology and Environment of the People’s Republic of China. The main drafting organizations of this Standard. Nanjing Institute of Environmental Sciences of the Ministry of Ecology and Environment; Institute of Soil Science of Chinese Academy of Sciences; Institute of Agricultural Resources and Regional Planning of Chinese Academy of Agricultural Sciences; Chinese Research Academy of Environmental Sciences. This Standard was approved by the Ministry of Ecology and Environment on May 17, 2018. This Standard shall be implemented since August 1, 2018. This Standard shall be interpreted by the Ministry of Ecology and Environment. Soil Environmental Quality - Risk Control Standard for Soil Contamination of Agricultural Land1 ScopeThis Standard specifies the risk screening values and intervention values for soil contamination of agricultural land, as well as the monitoring, implementation and supervision requirements. This Standard is applicable to the screening and classification of soil contamination risks of arable land. For garden plots and grassplots, this Standard may be taken as a reference.2 Normative ReferencesThe content of this Standard quotes the following documents or their clauses. In terms of references without a specific date, the latest edition applies to this Standard.

The risk screening values are shown in Table 1. 4.2 Other Items 4.2.1 The other items of the risk screening values for soil contamination of agricultural land are optional, including benzene hexachloride (BHC), dichlorodiphenyl trichloroethane (DDT) and benzo[a]pyrene. The risk screening values are shown in Table 2.5 Risk Intervention Values for Soil Contamination ofAgricultural Land 5.1 The items of the risk intervention values for soil contamination of agricultural land include cadmium, mercury, arsenic, lead and chromium. The risk intervention values are shown in Table 3.6 Application of Risk Screening Values and Risk InterventionValues for Soil Contamination of Agricultural Land 6.1 When the contaminant contents in the soil are equal to or lower than the risk screening values specified in Table 1 and Table 2, the risks of soil contamination of agricultural land are low, and they may be ignored under general circumstances; 6.2 When the contents of cadmium, mercury, arsenic, lead and chromium in the soil are higher than the risk screening values specified in Table 1, and equal to or lower than the risk intervention values specified in Table 3, there may be risks of soil contamination, for example, the edible agricultural products fail to comply with the quality and safety standards, and in principle, safe utilization measures shall be taken, such as. agronomic regulation and alternative plantation, etc. 6.3 When the contents of cadmium, mercury, arsenic, lead and chromium in the soil are higher than the risk intervention values specified in Table 3, there may be high risks of soil contamination of agricultural land, for example, 6.4 The classification of soil environmental quality shall take this Standard as the basis, combined with the results of coordinated monitoring of edible agricultural products, and delineated in accordance with the relevant technical regulations.7 Monitoring Requirements7.1 Monitoring Sites and Sample Collection 7.1.1 The layout of survey and monitoring sites and sample collection of soil contamination of agricultural land shall comply with the relevant technical regulations of HJ/T 166. 7.2 Analysis of Soil Contaminants8 Implementation and Supervision8.1 This Standard is supervised and implemented by the competent departments of ecological environment at all levels in conjunction with the relevant competent departments of agriculture and rural areas. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
