Problems solved by technology

[0004] Foreign developed countries have stipulated the biological categories required for the derivation of water quality benchmark thresholds, but due to the large number of biological groups, which organisms are used for water quality benchmark derivation, no specific list of sensitive test organisms is recommended

Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] See figure 1 Shown, the method for the present invention's screening water quality benchmark test organism is specifically as follows:

[0029] 1. Determination of native representative aquatic organisms

[0030] According to the principles of aquatic biology taxonomy, first determine the major categories of aquatic organisms. For example, aquatic organisms can be mainly divided into: fish organisms, crustaceans, amphibians, insects, molluscs, and segmental organisms. Then, the local representative aquatic organisms are mainly determined based on the extensiveness of biogeographical distribution, and the representative aquatic organisms are required to be distributed in at least 3 river basins or more than 4 provinces in my country.

[0031] 2. Data collection

[0032] For a certain type of representative aquatic organisms, according to the dat...

Abstract

The invention discloses a method for screening a water quality criteria testing organism. The method comprises the following steps of: 1, determining a local representative aquatic organism; 2, collecting and screening species toxicity data, and determining a pollutant with the highest toxicity; 3, collecting and screening the toxicity data of the pollutant, and sequencing the species sensitivity of the pollutant; 4, determining the water quality criteria testing organism. By adopting the method, the water quality criteria testing organism can be quickly determined, and the support is provided for national water environment protection and water quality criteria study.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a method for screening water quality benchmark test organisms. Background technique [0002] Water quality benchmarks are the scientific basis for the formulation of water quality standards, providing a scientific yardstick and scale for water environmental protection. In the process of formulating water quality standards, toxicological tests of pollutants need to be carried out for protected aquatic organisms. Therefore, the selection of test organisms for water quality standards is very important, which directly determines the threshold of water quality standards. [0003] Different aquatic organisms in aquatic ecosystems have different sensitivities to pollutants and environmental pressures. Among them, sensitive organisms are most vulnerable to environmental pressures and cause population fluctuations, which affect the stability and safety of the entire aquatic biologic...
