3 thoughts on “How to classify environmental testing, which test items are included?”

  1. The medium objects of environmental detection can be roughly divided into water quality detection, air detection, soil detection, solid waste detection, biological detection, noise and vibration detection, electromagnetic radiation detection, radioactive detection, heat detection, optical detection, sanitary detection, etc. What projects are the environmental testing content? What are the main contents of environmental testing? The following is as follows as the classification of environmental testing content: 1. Water quality monitoring objects with water quality pollution include unpolluted and contaminated natural water (river, river, lake, sea, sea, sea , Groundwater), various industrial wastewater and domestic sewage. The main monitoring items can be divided into two categories. One is a comprehensive indicator of water pollution, such as temperature, chroma, turbidity, pH value, conductivity, suspension, dissolved oxygen, chemical oxygen consumption and biochemical oxygen demand demand for oxygen demand demand Wait. The other type is toxic substances, such as phenols, cyanide, lead, chromium, cadmium, mercury, nickel and organic pesticides, and phenylphenia. In addition to the above monitoring items, the flow velocity and flow should be measured. 2. Monitoring of atmospheric pollution, air pollution monitoring is a pollutant and periodic content in the atmosphere. There are about 100 types of air pollutants that have been recognized. These pollutants are in the atmosphere in the form of molecular and particles. The monitoring items of molecular -like pollutants include sulfur dioxide, nitrogen dioxide, carbon dioxide, ozone, total oxide, hydrogen hydrogenation, and hydrocarbon compounds. The monitoring items of particle -shaped pollutants include TSP (total suspended particulate matter), PM10 (inhaled particulate matter), natural dust reduction and chemical composition of dust particles (such as heavy metals and polygon aromatic hydrocarbons). In addition, local areas can also add certain monitoring items (such as sour rain and fluoride detection) according to specific circumstances. The concentration of air pollutants has a password relationship with meteorological conditions. While detecting air pollution, it is necessary to determine weather parameters such as wind direction, wind speed, temperature, and air pressure. 3. Soil and solid waste monitoring soil pollution is mainly caused by two factors. One is industrial waste, mainly pollution of wastewater and waste residue immersion liquid; on the other hand, fertilizer and pesticide pollution. The main monitoring items of soil pollution are monitoring of harmful metals such as chromium, lead, cadmium, mercury, and residual organic pesticides in soil and crops. Solid waste includes industrial, agricultural waste and domestic waste. The main testing items are the dangerous characteristics of solid waste and the detection of domestic waste. 4. Bio -pollution detection of creatures on the earth, whether it is animals or plants, is directly or indirectly absorbed from the atmosphere, water body, soil, and sunlight. While they absorb nutrients, some harmful pollutants will also enter the organism, and some poisons will be enriched in different organisms, which will cause damage to the growth and reproduction of animals and plants and even die. Environmental pollutants through the enrichment of creatures and the transmission of the food chain ultimately endangered human health. Biological pollution testing is the test of environmental pollutants in the biological body. The testing items include heavy metal elements, organic pesticides, toxic inorganic and organic compounds. 6. Physical pollution monitoring includes environmental pollution monitoring of physical energy such as noise monitoring, vibration, electromagnetic radiation, radioactivity, and heat radiation. Noise monitoring, vibration, electromagnetic radiation, radioactive damage to the human body is different from chemical pollution, and when these physical quantities in the environment exceed the period threshold, it will directly harm people’s physical and mental health. Therefore, the pollution monitoring of physical factors is also an important part of environmental monitoring. The monitoring items are mainly the level of various physical quantities in the environment.

  2. 1. Water quality monitoring objects with water quality include unpolluted and polluted natural water (rivers, rivers, lakes, sea, groundwater), various industrial wastewater and domestic sewage.
    2, air pollution monitoring atmospheric pollution monitoring is a pollutant and periodic content in the atmosphere. There are about 100 types of air pollutants that have been recognized. These pollutants are in the atmosphere in the form of molecular and particles.
    3, soil and solid waste monitoring soil pollution is mainly caused by two aspects of factors. One is industrial waste, mainly for pollution of wastewater and waste residue.
    4. Ecological testing The reactions made by the changes in biological communities and biological groups, observation and evaluation ecosystems’ response to natural changes and artificial changes are the time and space pattern of various ecosystem structures and functions.
    5, biological pollution detection of creatures on the earth, whether it is animals or plants, is directly or indirectly obtained from the atmosphere, water body, soil, and sunlight. While they absorb nutrients, some harmful pollutants will also enter the organism, and some poisons will be enriched in different organisms, which will cause damage to the growth and reproduction of animals and plants and even die.

  3. The Ministry of Environmental Protection recently reviewed and principled the new standards of discharge of emissions from boiler atmospheric pollutants, domestic waste incineration pollutants, industrial pollutants, and non -road mobile mechanical diesel engine pollutants.
    Analysts said that the environmental protection industry can be said to be one of the industries with the most policy support in recent years. The “Twelfth Five -Year Plan” in the last two years of environmental protection is expected to accelerate. Related concept stocks are worthy of attention.
    The Ministry of Environmental Protection stated that in order to prevent and treat air pollution, the current “Boiler Air Pollutant Emissions Standards” will be revised and improved. The revised “Boiler Atmospheric Pollutant Emissions Standard” increases the emission limit of nitrogen oxides and mercury and their compounds in coal -fired boilers, stipulates the special emission limit of air pollutants, and cancels different emissions according to the functional area and boiler capacity. The limit of the limit, and the initial emission concentration limit of coal -fired boiler smoke and dust, improved the control requirements of various pollutants. At the same time, the Ministry of Environmental Protection revised and improved the current Ministry of Environmental Protection’s “Control Standards for Domestic waste incineration pollution”, and newly included the pollution control of the sludge produced by the daily sewage treatment facilities and the special incineration furnace of general industrial solid waste. The control requirements for the start, stove, failure, or accident discharge of domestic waste incineration stoves strictly strictly strictly discharge standards such as particulate matter, sulfur dioxide, nitrogen oxides, heavy metals and compounds of domestic waste incineration plants.
