    [ Focus on Chemical Machinery Equipment Network ] "Green water and green mountains are golden mountains and silver mountains".
    At present, China's economic development is in a transitional stage.
    The original development model at the expense of resources and the environment is gradually being replaced by a green and healthy new economic model
    .
    However, in the process of economic transformation, a series of remaining problems have been highlighted, such as soil pollution, and a lot of energy needs to be invested in management, investigation and restoration
    .

     
    Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment
    The land silently nourishes everything, but human activities make it the "last trash can" where various pollutants flow
    .
    In May of this year, the Ministry of Ecology and Environment issued the "Communiqué on the State of China's Ecological Environment in 2020"
    .
    According to the communiqué, the results of the detailed investigation of the soil pollution status show that the soil environment of agricultural land across the country is generally stable.
    The main pollutant affecting the soil environmental quality of agricultural land is heavy metals, of which cadmium is the primary pollutant
    .

     

      The soil can also be "sick"
     

      Water pollution and air pollution are obvious, because once sewage and waste gas are discharged, they are easily noticed by people in the discolored river water and the smelly air
    .
    The process of soil pollution is "silent": heavy metals contained in industrial and agricultural production, urban garbage, etc.
    seep into the soil day after day, and pollutants in the water and atmosphere will eventually return to the land, making it difficult to be affected.
    Discovered by naked eyes
    .

     

      The "hidden diseases" of the soil unknowingly accumulate in this way, like a "biological time bomb".
    Often people do not realize that the soil here is "sick" until a poisoning incident caused by soil pollution occurs
    .
    At this time, mankind has paid a painful price
    .

     

      According to the National Survey Bulletin on Soil Pollution Status released in 2014, the total soil pollution rate in the country exceeded the standard 16.
    1%
    .
    Among the pollutants, inorganic pollution (heavy metals) is the main one, followed by organic pollution (pesticides, antibiotics, etc.
    )
    .
    Among different types of soil, the over-standard rate of cultivated land is as high as 19.
    4%, involving a wide range of areas and large amounts of pollution, which endanger the quality and safety of agricultural products, the safety of human settlements and the safety of the ecological environment
    .

     

      Active progress in soil pollution prevention and control
     

      The soil environment is related to the quality and safety of agricultural products and the health of the living environment.
    It is a major issue to ensure that the people "eat and live with peace of mind"
    .
    In recent years, China has adhered to the overall thinking of prevention first, protection first, classified management, and risk management.
    With soil pollution risk management as the core, a series of effective measures have been adopted, and soil pollution prevention and control have made positive progress
    .

     

      During the "Thirteenth Five-Year Plan" period, the tasks specified in the "Ten Ten Articles" were successfully completed, and the prevention and control of groundwater pollution achieved initial results
    .
    The target task of "double 90%" for the safe utilization rate of contaminated farmland and the safe utilization rate of contaminated plots is to basically control the risk of soil pollution and initially curb the trend of increasing soil pollution
    .
    To achieve the goal of controlling the proportion of extremely poor quality of groundwater assessment points nationwide at about 15%
    .

     

      During the "Thirteenth Five-Year Plan" period, a total of 28.
    5 billion yuan of special funds for soil pollution prevention and control have been allocated in the field of ecological environment, focusing on supporting detailed investigations of soil pollution, control and restoration of contaminated soil, and prevention and control of heavy metal pollution
    .
    More than 200 soil remediation pilot projects have been completed nationwide
    .
    The Ministry of Science and Technology has set up a key research and development plan on "Soil Pollution Causes and Treatment Technologies on Sites", which directly supports 1.
    9 billion yuan in funding
    .

     

      Soil monitoring "outlet" is coming
     

      As the basis for the prevention and treatment of soil pollution, soil monitoring will inevitably speed up
    .
    It can be said that soil monitoring runs through to the prevention and control of soil pollution
    .
    In the initial basic work, the monitoring of soil pollution status and the distribution of contaminated plots needs to be monitored first, so as to find out the "family status"; in the later stage of risk assessment screening and evaluation of restoration effects, environmental monitoring services are also involved
    .
    Therefore, the soil monitoring industry will become a major outlet for the soil prevention and control industry
    .

     

      Soil security is an important part of national wealth, and soil environmental monitoring data is an important indicator for measuring soil security
    .
    Fully building a soil environment monitoring network and doing a good job in national soil environment monitoring is an important part of promoting the construction of ecological civilization
    .
    With the introduction of the concept of carbon neutrality, the "14th Five-Year Plan" and other policy support, as well as the continuous improvement of the financing environment, the relevant environmental protection industry segmentation track is expected to return to the high growth cycle
    .

     

      Soil environmental monitoring is an important subdivision of ecological civilization construction.
    Driven by important factors such as policy orientation, site redevelopment and utilization requirements, and increased environmental awareness, the market continues to improve, and environmental monitoring instruments with proprietary technology or equipment provision capabilities Equipment providers will occupy a place in the market
    .
