1 Scope of application

This standard specifies the basic terms and definitions related to the soil environment. This standard applies to soil description, soil sampling, soil monitoring and evaluation, soil remediation and risk management and control, and soil ecotoxicology. Commonly used terms and definitions.

2 General terms and definitions

2.1 soil soil A complex of loose porous material layers capable of growing plants on the surface of the land and its associated physical and geographic elements. 2.2 soil quality An umbrella term for soil properties related to soil use and function. It measures and reflects the characteristics, functions and changes of soil resources and the environment. The comprehensive sign is the comprehensive manifestation and quantity of the soil's ability to perform, maintain or improve its productivity, vitality and environmental purification under normal stress conditions. Spend. 2.3 soil structure The arrangement and combination of aggregates formed by soil mineral particles and organic matter, including aggregates, agglomerates, blocks, prisms, prisms, Columnar and flaky, etc. 2.4 soil texture Coarseness according to the composition of the relative content of minerals of different particle sizes in the soil. 2.5 soil pores The empty space between soil solid particles. 2.6 Soil pH soil reaction Characterizing the properties of soil acid-base state, it is determined by measuring the hydrogen ion concentration of soil extract under specific conditions. 2.7 soil fertility The ability of soil to provide and coordinate nutrients and environmental conditions for normal plant growth. 2.8 soil biodiversity The overall diversity and variability of soil organisms and the systems they comprise. 5.2 environmental fate analysis Analysis of pollutants released into the environment, their migration, transformation, accumulation and other processes. 5.3 sensitive target of soil environment Sensitive areas or objects related to the soil environment that may be affected by human activities. 5.4 Contaminant of concern According to the pollution characteristics of the plot, the requirements of relevant standards and regulations, and the opinions of the stakeholders of the plot, it is determined that soil pollution status investigation and Contaminants for soil contamination risk assessment. 5.5 source An area where the release of a substance or preparation results in one or more receptors (5.6) being at risk of potential exposure. 5.6 receptor It generally refers to the population or biological groups in the plot and its surrounding environment that may be affected by pollutants, and it can also generally refer to the affected functions around the plot. Water bodies and natural and human landscapes. 5.7 sensitive receptor Receptors most sensitive to pollutants among potential taxa affected by land pollutants. 5.8 risk analysis Use available information to identify hazards and characterize their risk. 5.9 risk assessment The process of analyzing and evaluating human and environmental damage in polluted areas, generally including the nature, extent, and probability of the damage. noodle. 5.10 pollutant release assessment An assessment of the likelihood and rate of release of pollutants based on pollutant characteristics and site characteristics. 5.11 quantitative risk assessment Using data from field surveys, using databases and numerical models of pollutant releases, environmental risk analysis, exposure assessment (5.12), environmental Environmental impact analysis and uncertainty analysis (5.21), evaluation of risk. 5.12 exposure assessment The process of determining how and to what extent a recipient is exposed to a source of contamination. 5.13 carcinogenic risk The probability that a population is exposed to a unit dose of carcinogenic effect pollutants daily to induce carcinogenic diseases or hazards. 5.14 non-carcinogenic risk The ratio of the daily ingested dose of a pollutant to the reference dose used to characterize the harm caused by exposure to a non-carcinogenic pollutant through a single route level, usually expressed as a hazard quotient. 5.15 hazard identification According to the data obtained from the soil pollution status survey, combined with the land (planning) utilization method of the plot, determine the pollutants, land Spatial distribution of pollutants within the block and possible sensitive receptors such as children, adults, ecosystems, groundwater bodies, etc. 5.16 toxicity assessment Based on the work of hazard identification, analyze the harmful effects of the pollutants of interest on sensitive receptors, and determine the toxicity related to the pollutants of interest parameter. 5.17 risk characterization Integrate the results of exposure and toxicity assessments to quantify and spatially characterize risk, and discuss assumptions, The process of parameter and model uncertainty. 5.18 human health risk assessment The process of predicting the likelihood of harmful effects of environmental pollutants on human health. 5.19 ecological risk assessment Apply quantitative methods to assess and predict the possible risks of various environmental pollutants to biological systems and assess the risk acceptability. pattern or method. 5.20 acceptable risk level A level of risk that will not produce adverse or detrimental health effects on sensitive receptors. 5.21 uncertainty analysis The comprehensive analysis and evaluation of the uncertainty factors in the risk assessment process is called uncertainty analysis. Inaccurate results of land risk assessment Qualitative analysis is mainly to analyze the model simulation results caused by the input parameter error and the uncertainty of the model itself in the process of land risk assessment. Qualitative or quantitative analysis of uncertainty, including risk contribution rate analysis and parameter sensitivity analysis, etc. 5.22 soil contamination risk of agricultural land The quality and safety of edible agricultural products, crop growth or soil ecological environment are adversely affected due to soil pollution. 5.23 risk screening values for soil contamination of agricultural land If the content of pollutants in the soil of agricultural land is equal to or lower than this value, it will not affect the quality and safety of agricultural products, the growth of crops or the ecological environment of the soil. The risk is low and can be ignored in general; if the value exceeds this value, there may be adverse effects on the quality and safety of agricultural products, crop growth or soil ecological environment. Risks, soil environmental monitoring and coordinated monitoring of agricultural products should be strengthened, and safe utilization measures should be taken in principle. 5.24 risk intervention values for soil contamination of agricultural land agricultural land If the pollutant content in the soil of the agricultural land exceeds this value, the edible agricultural products do not meet the quality and safety standards or the risk of soil pollution in the agricultural land is high. In principle, strict control measures should be taken. 5.25 soil contamination risk of land for construction People living and working on construction sites are exposed to pollutants in soil for a long time, resulting in chronic toxic effects or carcinogenic effects on health. Negative Effects. 5.26 Risk screening values for soil contamination of land for construction land construction Under a specific land use mode, if the pollutant content in the soil of construction land is equal to or lower than this value, the risk to human health can be Ignore; if the value exceeds this value, there may be risks to human health, and further detailed investigation and risk assessment should be carried out to determine the specific pollution scope and level of risk. 5.27 risk intervention values for soil contamination of land for construction land construction Under a specific land use mode, if the pollutant content in the soil of construction land exceeds this value, there is usually an unacceptable risk to human health. risk, risk control or remedial measures should be taken.

6 Soil remediation and risk management

6.1 General terms and definitions 6.1.1 soil pollution Human factors cause certain substances to enter the surface soil of the land, causing changes in soil chemical, physical, biological and other characteristics, affecting soil soil function and effective use, endangering public health or destroying the ecological environment. 6.1.2 soil protection Measures taken to maintain or restore the original function of the soil for a long time. 6.1.3 soil restoration Measures to improve damaged or degraded soils to restore targeted functions. 6.1.4 soil remediation Use physical, chemical or biological methods to fix, transfer, absorb, degrade or transform pollutants in the soil of the plot to reduce their content to acceptable levels, or the process of converting toxic and harmful pollutants into harmless substances. 6.1.5 natural attenuation Utilize physical, chemical and biological processes that naturally occur in contaminated areas, such as adsorption, volatilization, dilution, diffusion, chemical reactions, biological Degradation, bio-fixation and bio-decomposition, etc., reduce the concentration, quantity, volume, toxicity and mobility of pollutants. 6.1.6 in-situ remediation Contaminated soil or groundwater is not moved, and it is repaired or treated directly at the location of the contamination of the plot.
