1. Definition of environmental pollutant standards: environmental pollutant standards refer to standards with known levels that are used in environmental monitoring, monitoring and determination.
two。 Application of standardized products of environmental pollutants: standardized products of environmental pollutants shall be widely used in environmental monitoring, monitoring and regulation. For example, in water monitoring, environmental pollutant standards can be used to calibrate water monitoring instruments to ensure the accuracy of monitoring results.
3. Equipment of environmental pollutant standards: the equipment of environmental pollutant standards mainly includes chemical synthesis, classification, characterization and other steps. Among them, isolation is the key step of environmental pollutant standardization, which is usually carried out by using techniques such as chromatography, electrophoresis, extraction and so on.
4. Quality control of environmental pollutant standard products: the quality of environmental pollutant standard products directly affects the accuracy of environmental monitoring and monitoring, so quality control measures are needed. It usually includes standard product standard check, standard check, qualitative check and so on.
5. Lack of standard products of environmental pollutants: because there are many kinds of environmental pollutants and have varying degrees of toxicity and harmfulness, the lack of standard products of environmental pollutants has become an important problem in pre-research and application.
Progress in the research on environmental pollutant standards: in recent years, with the continuous increase in the demand for environmental monitoring and monitoring, more and more attention has been paid to the research and application of environmental pollutant standards. Some new environmental pollutant standards have been produced and widely applied. At the same time, some studies have put forward new equipment methods and quality control strategies for the shortcomings of the existing environmental pollutant standards.
