Haidian District Ecological Environment Bureau promotes the prevention and protection of soil pollution prevention and protection ecological environment

Recently, on the roadside in Haidian Park, several staff members squatted on the grass, dug out a small pit about 20 cm deep with a small iron shovel, and then changed to the soil on the surface little by little. The carefulness of details attracted the people in the past to watch. What are you doing? Wang Chaochao, a staff member of the Ecological Environment Bureau of the Ecological Environment Bureau, told reporters: "This is doing soil sampling work to ensure the effectiveness of ecological environmental protection and ecological civilization construction in our district."

Soil is the basis of agricultural production, the carrier of food production, and the material basis that humans live in. The quality of soil quality is directly related to the quality of agricultural products, human health, and sustainable economic and social development. In the first half of this year, the safety utilization rate of the pollution land and the safety utilization of polluting cultivated land in our district reached more than 93%, and the safety utilization of key construction land was effective to obtain effective guarantee. "Grasp the co -management, continue to increase the intensity, extend the depth, and expand the breadth, and make every effort to ensure the safety of the soil environment in the jurisdiction. As of now, the soil environmental quality of the area is generally good, and the risk of soil pollution has been effectively preventing and controlling.

Routine monitoring

"Escort" for soil safety

"The iron shovel is a metal. After digging a pit, you need to peel off the surface to contact the soil of the metal shovel with a wooden shovel to avoid affecting the monitoring results of the soil." The staff sampled in Haidian Park introduced to reporters while continuing to continue to report to reporters while continuing to continue to continue sampling. According to the requirements, the shallow samples need to be collected at 0-20 cm surface soil samples. The monitoring indicators are soil physical and chemical indicators, inorganic pollutants and organic pollutants. The reporter saw that the sample personnel buckled the soil with tools similar to a rough needle. As soon as they were mentioned, the collected soil entered the "needle tube", and then pushed to the brown blowing bottle, and then used a small wooden shovel to put the soil separately to the soil separately. Put in several small glass tanks and pallets, and record the coordinates of soil points, the surrounding environment, depth of sampling, sampling of school compatibility personnel conditions, etc. to ensure the representativeness of soil samples.

The sampling person told reporters: "The samples of each point need to be dug 5 such small pits nearby. The randomness of 1 point is too high. Pour in the tray, mix and pick out the stone branches in the soil -like, divide the soil according to the 4 -point method, collect the two piles before and after, so that the soil sample after mixing can basically represent the plot, and then dry it after drying it. The steps of drying, grinding, sieved, and dissolution, and finally formed a sample that can be on -machine ', and monitoring the monitoring of volatile organic matter and semi -wave -wave -oriented organic matter, respectively. "

"Monitoring is an important means to ensure soil safety. So as to master the real situation of the soil environment and further promote the supervision of soil environment. "The relevant person in charge of the District Ecological Environment Bureau introduced.

"This year, Haidian District launched soil monitoring and evaluation work, covering the relevant agricultural land, centralized drinking water sources, unused land, park green space, etc. in the jurisdiction. A total of more than 350 soil monitoring points were set up. To accurately grasp the situation of the soil environment in the jurisdiction, once there is a situation of exceeding the standard, it will quickly take corresponding risk prevention measures to effectively ensure that residents in the jurisdiction can rest assured and live with peace of mind. "Wang Chaochao introduced.

Overall

About 350 soil monitoring evaluation points

Soil security is related to the people of the people "vegetable baskets", "rice bags" and "tongue safety". Our district coordinates soil prevention and control work, give full play to the role of the comprehensive prevention and control work group of the Ecological Civilization Committee of the District Committee of the District Party Committee, prints and implement the implementation of the Haidian District pollution prevention and control operation plan, arrange key tasks and tasks, refine work measures, clarify the time node, and clarify the time node. Compact departmental responsibilities and promote the successful implementation of soil pollution prevention and control.

In order to continue to strengthen the risk prevention of construction land, the District Ecological and Environment Bureau has increased the supervision of key soil units, combined with actual production conditions, updated and disclosed the list of key soil units, organized the deployment of soil pollution prevention work, and urged key units to strictly implement self -monitoring on its own monitoring. , Hidden danger investigation and other subject responsibilities. At the same time, the survey of soil pollution of construction land, focusing on land use changes to the "one living and two public" plots, and completed the investigation and review of the soil pollution status of 5 plots. The results show that the soil and groundwater meet the next step. Planning requirements.

"We also carried out the pilot work of the soil environment survey, screening the list of projects intending to use old factories to transform into public management and public service purposes, conducting investigations on the eligible plots according to the plan, complete data collection and policy promotion on schedule. Promoting soil environment survey. "Wang Chao introduced.

In the first half of this year, our district completed the on -site survey of the 2021 -closed corporate plot, and set up 32 soil environment monitoring points. At present, the collection of soil samples that have been completed has been completed.

In order to effectively ensure the safety of agricultural land, the District Ecological Environment Bureau strictly resumes and reclaims the land management work, and has completed the survey of the soil pollution status of two plots of land reclamation projects in Xibu Tou Village and Nanyuhe Village, Shangzhuang Town, Sujiabu Town. The judges showed that the quality of soil and groundwater met the planning requirements.

In the survey and evaluation of agricultural land soil, in response to the two typical facilities agricultural land of Baiwang Plantance and Flei Farm, data collection and soil environment survey were carried out. Scientifically set up 20 soil monitoring points, and all samples have been completed. And 100 farmland irrigation wells are included in the scope of annual water quality monitoring and supervision and inspection, and the sampling and inspection work is promoted in an orderly manner. In order to deepen the reduction of pesticides and pesticides and the use of agricultural waste resources, our district has formulated and issued the "Work Plan for the Recycling and Disposal of Agricultural Milk and Pesticide Packaging Waste Recycling of Haidian District in 2022" "2022 Pesticide reduction and downside control work plan" and other documents, and carry out the demonstration meeting of Beijing -western rice fertilizer reduction experts, update the new rice -type slow -controlling fertilizer formula, track the growth of rice application slowly, and carry out corn fertilizer. Utilization experiment and topdressing.

目前，全区共布设土壤环境监测评估点位350余个，覆盖5个镇的农用地、3个市级和5个镇级集中式饮用水水源地、未利用地、园林绿地以及部分企业和Around the school and so on. (Reporter Gao Yughao/Wen Wang He/Photo)
