The standardized products of environmental pollutants refer to the standardized substances used in environmental monitoring and inspection analysis. They are developed in accordance with certain quality and quality requirements, and can be used to calibrate environmental testing devices, to determine the emission levels of environmental pollution sources, and to assess the impact of environmental pollution on human health and health systems.
Common environmental pollutant standards include:
1. Standard products for major pollutants: such as sulfur dioxide, nitrogen oxides, sporadic organic substances, etc.
2. Standard of water pollutants: such as ammonia nitrogen, total nitrogen, total phosphorus, chemical oxygen demand, etc.
3. Standard products of soil pollutants: such as heavy gold, organic pollutants, etc.
4. Standard products for contaminants: such as grade grade, etc.
The production of environmental pollutant standard products requires strict quality control to ensure their quality and quality. It is usually necessary to go through laboratory tests and certificates, and to carry out production and standards in accordance with relevant standards and specifications. In the use of environmental pollutant standards, it is necessary to follow the corresponding use instructions and operational rules to ensure their accuracy and reliability.
