Environmental monitoring

Environmental supervision and management is the scientific management of the whole process of environmental monitoring. The specific contents include: management of monitoring standards, management of monitoring points, management of sampling technology, management of sample storage and storage, management of monitoring methods, and data of monitoring data. Management, supervision side quality management, supervision side comprehensive management and supervision side network management, etc. Although there are many contents of monitoring technology management, its core content is the environmental supervision side quality assurance. The basic requirements for monitoring data and conclusions are as follows: .

(1) Accuracy: The degree to which the measured value is consistent with the true value.

(2) Precision. Uniform sample repeats the degree of conformity of multiple times.

(3) Integrity: The extent to which the total amount of valid monitoring data is met to meet the expected planning requirements.

(3) Substitute: The degree of representation of the monitored sample in the spatial and temporal distribution.

(4) Comparability; the degree of agreement between the data obtained under comparable conditions such as monitoring methods, environmental conditions, and data expression.

(5) Scientific: The method of comprehensive analysis of data on the supervision side and the conclusion of environmental issues must be scientific.

In order to strengthen the quality management of environmental monitoring and ensure the reliability of monitoring data, the State Environmental Protection Administration

The relevant provisions of the Environmental Protection Law of the People's Republic of China and the Regulations on the Administration of the National Environmental Supervision Side have formulated the Regulations on Quality Assurance Management of Environmental Supervision (Provisional, 1991), which implements hierarchical management of the guarantee work of quality assurance, and the sufficient value for quality assurance. The basic requirements of the transfer, laboratory and supervisory personnel, the quality assurance work content and the quality assurance report system have made specific requirements. The monitoring of the sub-environment is a complicated process. Therefore, the different aspects of environmental monitoring and management are different. In addition, the management of the supervision file is also the content of the supervision of the supervision, that is, all the documents for the whole process of monitoring include the review of the source of the task, the formulation of the plan, the layout, the sampling, the analysis method, the operation status of the instrument, and the monitoring instrument. Data, data processing, comprehensive evaluation, etc. shall be recorded and archived in accordance with a strict system, and the data and data of the fruit product shall be collated and a database shall be established. This is of great significance to ensure the quality of the environmental monitoring side.
