Detailed Description
The principles and features of this invention are described below in conjunction with examples which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
As shown in fig. 1, a method for determining a risk of soil contamination includes:
step 1, obtaining a soil sample of a pollution risk area to be judged, and processing the soil sample to obtain an evaluation index set;
step 2, based on a preset weight, carrying out weight calculation on the evaluation index set;
step 3, judging the risk category of the pollution risk area to be judged based on the weight calculation result;
and 4, performing corresponding processing according to the risk categories.
In some possible implementation modes, the evaluation index set obtained by processing the soil sample can improve the accuracy of risk judgment of the area, meanwhile, the evaluation indexes needing to be used are screened out, so that the judgment efficiency can be improved in the subsequent processing process, the influence degree of various index factors on the risk judgment can be considered in a calculation mode of weight, and the finally obtained risk judgment result is more fit to the reality and has more authenticity and accuracy.
It should be noted that the evaluation index set in step 1 is obtained by taking a second-class land screening value in soil environment quality construction land soil pollution risk management and control standard (trial) in GB36600-2018 and a class iv water quality standard limit value in groundwater quality standard (GB/T14848-2017) as evaluation standards for judging soil and groundwater pollution. According to pollution identification of industrial parks (pollution identification modes include but are not limited to regional environment data collection, site survey, personnel interview and the like), and by combining the statistical analysis result of pollutant data, characteristic pollutants of parks, such as benzene, benzo [ alpha ] pyrene, chlorohydrocarbon and the like, are screened out. The physicochemical characteristics, the toxicity degree, the migration rule and the potential influence on underground water, the quantity, the detection frequency, the accumulation, the overproof condition and the like of the characteristic pollutants are key parameters reflecting the characteristic pollutants of the soil in the garden. After the above process, the following evaluation indexes can be obtained: the detection frequency of the characteristic organic pollutants, the maximum accumulation index of the characteristic pollutants, the number of the overproof pollutants, the proportion of the overproof samples, the toxicity of the overproof pollutants, the air diffusion coefficient of the overproof pollutants, the distance between the maximum pollution depth of the soil and the water level of underground water, the water phase solubility of the soil overproof pollutants and the overproof number of the characteristic pollutants in the underground water.
The following explanation is made by taking the above 9 evaluation indexes as examples to preset weights in the present scheme:
1) the frequency of detection of characteristic organic pollutants is an important parameter for measuring the pollution complexity of a certain park and the overall distribution of the pollutants in the park. Since the background of the soil contains inorganic substances such as heavy metals, the investigation focuses on the detection of organic characteristic pollutants. Specifically, the detection result of a certain organic pollutant is higher than the detection limit of the substance by the method, namely the detection is carried out; the ratio of the detected sample quantity to the total detected sample quantity is the detection rate. If the detection frequency of a certain pollutant is higher than 30%, the contingency caused by detection errors is basically eliminated, and the substance is very likely to accumulate in the soil of the garden and even pollute the soil. The more contaminant species are detected with a frequency greater than 30%, the more complex the pollution situation in the park and the greater the corresponding safety risk value should be. Therefore, the index weight is assigned as 1, and the index is divided into four sections.
a) If the detection frequency of all organic pollutants is lower than 30%, the identification result of the characteristic pollutants of the park is considered to have larger uncertainty. Assigning a value of 0;
b) and if the number of the organic pollutants with the detection frequency higher than 30% is 1, the uncertainty of the characteristic pollutant identification result of the park is considered to be small, and the types of the pollutants are single. Assigning a value of 1;
c) and if the number of pollutants with the detection frequency higher than 30% is 2-5, the uncertainty of the characteristic pollutant identification result of the park is considered to be small, and the types of the pollutants are relatively complex. Assigning a value of 3 points;
d) and if the number of pollutants with the detection frequency higher than 30% is more than 5, the uncertainty of the characteristic pollutant identification result of the park is considered to be small, and the types of pollutants are complex. And 5 points are assigned.
2) The maximum characteristic pollutant accumulation index is an important reference index for screening site heavy metal pollution or potential heavy metal pollution, and is particularly suitable for regional soil environment risk early warning analysis, so that the index is assigned with a weight of 2 and is assigned in four sections.
a) And if the maximum accumulation index of the characteristic pollutants of the garden is less than 0, the possibility of potential soil heavy metal pollution of the garden is considered to be low. Assigning a value of 0;
b) and (3) considering that the maximum accumulative index of the characteristic pollutants in the park is between 0 and 1, and the potential pollution of the soil heavy metal in the park has certain possibility. Assigning a value of 1;
c) and (3) considering that the probability of the potential soil heavy metal pollution of the park is high when the maximum accumulative index of the park characteristic pollutants is between 1 and 3. Assigning a value of 3 points;
d) and if the maximum accumulation index of the characteristic pollutants in the park is more than 3, the possibility of potential soil heavy metal pollution in the park is considered to be high or the phenomena of standard exceeding of the soil heavy metal pollution and the like occur. And 5 points are assigned.
Wherein the index of accumulated geological pollution (I)geo) The calculation method comprises the following steps: i isgeo＝log2(Cn/1.5Bn)
In the formula: cnThe measured concentration of a certain element n in the soil sample; b isnThe soil background concentration of a certain element n; and 1.5 is a dimensionless correction index.
3) The amount of the overproof pollutants is the most important parameter for measuring the pollution degree of a certain park. In particular to the type number of the pollutants in the soil, which exceeds the screening value of the second type of land in soil pollution risk management and control standard (trial) of soil environment quality construction land (GB 36600-2018). The more the types of the overproof pollutants are, the more complex the pollution condition of the park is, and the larger the corresponding comprehensive risk is. Therefore, the index weight is assigned to 5, and the index is divided into four sections.
a) And if the number of the overproof pollutants in the park is 0, the possibility of potential soil pollution in the park is considered to be low. Assigning a value of 0;
b) and if the number of the overproof pollutants in the park is 1, the soil pollution condition of the park is relatively simple, and the comprehensive risk is relatively small. Assigning a value of 2;
c) and if the quantity of the overproof pollutants in the park is between 1 and 5, considering that the soil pollution condition of the park is relatively complex, and the comprehensive risk is relatively large. Assigning a value of 4 points;
d) and if the quantity of the overproof pollutants in the park is more than 5, the soil pollution condition of the park is considered to be complex, and the comprehensive risk is great. And 6 points are assigned.
4) The proportion of the overproof sample is the most important parameter for measuring the pollution degree of a certain park. Specifically, the ratio of the number of second-class land screening values in a detection result of a certain pollutant exceeding soil pollution risk control standard (trial) for soil environmental quality construction land (GB36600-2018) to the total number of pollutant detection samples is referred to. For example, if a plurality of pollutants in a certain park exceed the standard, the pollutant with the highest proportion is taken as the standard when the exceeding proportion of the pollutants is determined. The greater the ratio, the greater the pollution level and extent of the park may increase, and the more complex the corresponding pollution prevention and control and remediation measures. Therefore, the index weight is assigned to 2, and the index is divided into four sections.
a) And if the ratio of the overproof samples in the park is 0, the possibility of potential soil pollution in the park is considered to be low. Assigning a value of 0;
b) and if the proportion of the overproof samples in the park is less than or equal to 10%, considering that the pollution range in the park is relatively small. Assigning a value of 2;
c) and if the proportion of the overproof sample in the park is between 10 and 30 percent (including 30 percent), considering that the local area in the park has pollution. Assigning a value of 3 points;
d) and if the proportion of the overproof samples in the park is more than 30%, determining that the polluted area in the park is relatively large. And 5 points are assigned.
5) The toxicity of the overproof pollutants is one of the important bases for judging the comprehensive risk level of the pollution in the park, and particularly refers to the capability of the pollutants to cause harm to human health. Because carcinogenic substances are generally high in toxicity degree and harm capability, long-term accumulation effect is achieved, influence on human health and ecological environment is large, and the carcinogenic substances are generally pollutants which are mainly concerned in the field of environmental protection. Therefore, when the toxicity degree of the overproof pollutants is measured, the method takes the types of carcinogens as a dividing basis, and particularly refers to the classification of carcinogens by the International research center for cancer (IARC). The index weight is assigned to 2, and the index is divided into four sections.
a) And if the pollutant in the park exceeding standard does not contain carcinogenic substances, the pollutant in the park is considered to be low in toxicity. Assigning a value of 0;
b) if 1 carcinogen exists in the overproof pollutants in the park, the toxicity of the pollutants in the park is considered to be slight. Assigning a value of 1;
c) and 2-5 carcinogenic substances exist in the overproof pollutants in the park, and the pollutants in the park are considered to be moderate in toxicity. Assigning a value of 3 points;
d) and (4) if more than 5 carcinogenic substances in the overproof pollutants in the park are present, the pollutants in the park are considered to be high in toxicity. And 5 points are assigned.
6) The air diffusion coefficient of the overproof pollutant refers to the gas quantity passing through a unit area in unit time when the concentration gradient of the pollutant is one unit, and is an important parameter of the volatilization characteristic of the pollutant, and can be determined by referring to a table B.2 in appendix B of technical guidance for evaluating the soil pollution risk of construction sites (HJ 25.3). Generally, pollutants with higher volatility are easier to migrate and diffuse in soil, have more exposure paths and are exposed in a larger amount, so the influence on environmental safety is larger. The index weight is assigned to 2, and the index is divided into four sections.
a) If the air diffusion coefficients of the overproof pollutants in the park are all 0 or no data, the volatility of the overproof pollutants in the park is considered to be weak, and the value is assigned to 0 point;
b) the maximum value of the air diffusion coefficient in the overproof pollutants in the garden ranges from 0 to 5 multiplied by 10-2(containing 5X 10 of-2) And meanwhile, the volatility of the overproof pollutants in the park is considered to be low. Assigning a value of 1;
c) the maximum value of the air diffusion coefficient in the overproof pollutants in the garden is 5 multiplied by 10-2～1×10-1(containing 1X 10-1) And if so, the park overproof pollutant is considered to have moderate volatility, and the value is assigned to 3 points;
d) the maximum value of the air diffusion coefficient in the overproof pollutants in the garden is more than 1 multiplied by 10-1And considering that the overproof pollutants in the park are volatile, and assigning a value of 5 points.
7) The distance between the maximum soil pollution depth and the groundwater level refers to the distance between the deepest overproof position of the soil sample at a certain point and the groundwater level at the point. Generally, the smaller the distance is, the shorter the time for the pollutants to migrate to the groundwater, and once the pollutants migrate to the groundwater, the migration speed and the migration range of the pollutants are rapidly increased, so that a more serious safety risk is caused, therefore, the index is assigned with a weight of 1 and is assigned in four sections.
a) The existing investigation conclusion proves that the pollutants are transferred to the underground water, which indicates that the soil pollution influences the environmental safety of the underground water, and the value is assigned for 10 minutes;
b) the distance between the polluted soil and the groundwater level is 0-3 m (including 3), which indicates that the possibility of soil pollution migration to groundwater is very high, and the value is assigned for 5 points;
c) the distance between the polluted soil and the groundwater level is 3-10 m (10 inclusive), which indicates that the probability of soil pollution migration to groundwater is high, and the value is assigned for 3 points;
d) if the distance between the contaminated soil and the groundwater level is greater than 10m, the possibility that the soil contamination migrates to the groundwater is low, and the value is assigned to 1 point.
8) The water phase solubility of the soil overproof pollutant refers to the quality of the soil overproof pollutant dissolved when the soil overproof pollutant reaches a saturated state in 100g of water at a certain temperature, and is one of important parameters influencing the migration of the pollutant into underground water, and the water solubility can be determined by referring to a table B.2 in appendix B of technical guidance for evaluating the soil pollution risk of construction sites (HJ 25.3). Substances with high solubility are easy to rapidly migrate downwards along with the leaching action of surface water, so that the pollution risk to underground water is relatively large. The index weight is assigned to 1, and the index is divided into four sections.
a) Maximum solubility value of 1X 10 or less-6mg/L, the rate of migration to underground water is very slow, and the value is assigned for 1 min;
b) maximum solubility value of 1X 10-6～1×10-3mg/L (containing 1X 10)-3) In between, the speed of transferring to underground water is relatively slow, and the value is assigned for 2 points;
c) maximum solubility value of 1X 10-3About 1mg/L (including 1), the migration rate to underground water is relatively medium, and the value is assigned for 3 minutes;
d) a maximum solubility value greater than 1mg/L would result in a relatively fast rate of migration to groundwater giving a score of 5.
9) The overproof quantity of the characteristic pollutants in the underground water refers to the quantity of the pollutants which are detected in the underground water and exceed the limit of the IV-class standard in the underground water quality standard (GB/T14848-2017). For most industrial parks, shallow groundwater is basically not used as a drinking water source, but other utilization modes cannot be eliminated, so that the exceeding of the characteristic pollutants in the groundwater can cause health risks to human bodies. The index weight is assigned to 2, and the index is divided into four sections.
a) And if the overproof quantity of the characteristic pollutants of the garden groundwater is 0, the influence of the garden groundwater on the health risk of the human body is considered to be weak. Assigning a value of 0;
b) and if the exceeding amount of the characteristic pollutants of the groundwater in the garden is 1, the groundwater in the garden is considered to have certain influence on the health risk of a human body. Assigning a value of 1;
c) and if the exceeding quantity of the characteristic pollutants of the garden groundwater is 1-5, the influence of the garden groundwater on the health risk of the human body is considered to be large. Assigning a value of 3 points;
d) and if the exceeding quantity of the characteristic pollutants of the garden groundwater is more than 5, the influence of the garden groundwater on the health risk of the human body is considered to be great. And 5 points are assigned.
It should be noted that the above is only an example, in the actual operation process, the number of the evaluation indexes may be adaptively adjusted according to the actual situation, and the preset weight for each evaluation index may also be adjusted according to the influence factors such as the specific environment.
And according to the preset weight, the score of each evaluation index can be correspondingly searched, and the scores are superposed to obtain a weight calculation result.
