Embodiment 1

[0091] Question raised: Taihu Lake sediment heavy metal pollution level.

[0092] S1 Determination of the environmental medium: Taihu Lake sediments;

[0093] S2 selects pollutants to be diagnosed: heavy metals, Cu, Zn, Pb, Ni, Cr, Cd, As, Hg;

[0094] S3 analyzes and diagnoses the concentration of pollutants in the environmental medium;

[0095] S3.1 Set the scope of data acquisition:

[0096] CNKI database, Wanfang database, Web of Science, and other unpublished databases include data from national automatic monitoring stations and laboratory analysis data; in addition, resources not included in public databases include university databases that have not signed CNKI agreements, Chinese Academy of Sciences Chinese Academy of Sciences Literature Database)

[0097] S3.2 Determine the data collection rules:

[0098] 1) The investigation is carried out on the scale of the whole Taihu Lake;

[0099] 2) Data collection time range: January 2000 --- December 2018;

[0100] 3) I...

Abstract

The invention belongs to the technical field of environmental pollutant prevention and control, and particularly relates to a method for diagnosing the concentration level of environmental medium pollutants. The method comprises the following steps: S1, determining an environmental medium; S2, selecting pollutants to be diagnosed; S3, analyzing and diagnosing the concentration of pollutants in theenvironmental medium; S4, concluding: analyzing and summarizing the result of the concentration level of the pollutants in the environmental medium. S3 specifically comprises the following operations: S3.1, setting a data acquisition range; S3.2, determining a data acquisition rule; S3.3, sorting, merging and calculating data; S3.4, sampling data; S3.5 performing pollution level evaluation. According to the method, data with the same investigation range and the same investigation purpose are summarized, the investigation frequency and the number of investigation samples are indirectly increased, sampling errors caused by the small number of investigation samples are avoided, the accuracy of environmental pollution concentration level analysis is improved, and a manager can make a pollution prevention and control strategy easily.

Description

technical field [0001] The invention belongs to the technical field of environmental pollutant prevention and control, and in particular relates to a method for diagnosing the concentration level of environmental medium pollutants. Background technique [0002] The rapid economic development has led to frequent occurrence of various pollution incidents in our country, resulting in different pollution conditions of air, water, soil and other environmental media. Accurately grasping the types and levels of pollutants in environmental media is the basis and key to effective pollution prevention and control. At present, the survey of pollution status is usually completed by means of on-site investigation and laboratory analysis. The survey data formed in this way is one of the indispensable ways for the diagnosis of environmental problems. However, from a management point of view, due to the large investment in manpower and material resources in field investigations; the variet...
