Interpretation of environmental monitoring management measures, what management is not included in t

Formalization.

Principles: 1. The principle of reasonable selection of monitoring objects should be considered from the following three aspects when selecting air survey objects:

1. On the basis of the field investigation of Tong Jianzhao, according to the nature of the pollutants, select the pollutants with high toxicity and serious harm and large impact range.

2. There must be reliable testing methods and effective analysis methods for the selected pollutants, so as to ensure that accurate, reliable and representative data can be obtained.

3. If the monitoring data has no standard to follow, and does not understand the impact on human health and biology, the monitoring work will fall into blindness.

Generally, yes. Monitoring the same bright samples with different monitoring methods will give different results, and it is better to compare them with the same method.

If the entrusting unit requires a certain method of monitoring, it can be noted on the power of attorney.

Blue is the color of the logo of the intrinsically safe circuit (instrument operator's manual), which is to distinguish it from ordinary lines and facilitate maintenance.

There are no national and industry standards for intrinsically safe cables themselves.

What information are you talking about? At present, the monitoring data of environmental monitoring and national control are published to the outside world, and the Ministry of Environmental Protection of the People's Republic of China has a data release platform, as well as some other self-monitoring publication platforms.

The truth of the data is not necessarily easy to use, and it is not necessary to do tricks after the data is obtained, but before or at the stage of data acquisition.

For example, if you measure, it will be 200, and then modify it to 100 (no one dares to do this); If you put the meter in the garden or in the green belt, it may be 200, but you measure 100 or less, but the data is completely true. It's just that the information is not representative.

To do the following:

1. Truly ensure that the detection of environmental monitoring institutions is not affected by any constraints, and monitoring is carried out in strict accordance with the method standards;

2. Environmental monitoring personnel meet the monitoring requirements in terms of professional ethics, technical level and testing management, and be scientific, accurate and open.

The above actions can ensure the authenticity and accuracy of the test report, without "moisture".

The quality assurance requirements of environmental monitoring require which five aspects of monitoring data must be met

Representativeness: The sample collected must reflect (represent) the actual situation of the sample being tested as a whole.

Accuracy refers to broadness: to characterize the accuracy of environmental detection in terms of accuracy. It determines the reliability of the analysis results. It is usually expressed by error or relative error, and its accuracy is evaluated by the scaled ** rate.

Precision: Precision is usually expressed in terms of standard deviation and relative standard deviation. Precision is evaluated by parallelism, repeatability, and reproducibility.

Comparability: Consistency of accuracy is required for monitoring results from the same laboratory and different laboratories. The t-test of mathematical statistics is usually used to test their significance differences and evaluate their comparability.

Integrity: Environmental monitoring should ensure that the expected monitoring plan obtains systematic, continuous and effective sample monitoring and integrity.

The safety of this guess belt stipulated by the national standard.

Do you have to add a buffer?

Yes, it is a must.

Qualification Review Discussion:

Environmental monitoring method standards should be selected to match quality standards, emission standards, etc. That's right.
