Problems solved by technology

However, the current water quality benchmark research and water quality evaluation mainly involve priority control pollutants, pesticides are mainly organochlorine and organophosphorus pesticides, and there are very few researches on water quality benchmark and water quality evaluation of pyrethroid pesticides

Embodiment 1

[0106] The derivation method of water quality benchmarks for pyrethroid pesticides in aquatic organisms includes the following steps:

[0107] S1. Data collection and screening

[0108] (1) Obtain data from the database, the data includes freshwater aquatic organism toxicity data, water physical and chemical parameter data, material inherent physical and chemical property data and environmental distribution data, the database includes domestic and foreign toxicity databases, native species measured data, public Published literature or reports;

[0109] (2) Perform data reliability judgment on the acquired data to obtain reliability data;

[0110] In order to ensure the scientificity of the water quality standard, the present invention needs to evaluate the reliability of the data. The basis for judging data reliability mainly includes 1) whether international and national standard test methods and industry technical standards are used, and whether the operation process follo...

Abstract

The invention belongs to the technical field of water quality safety assessment, in particular to a deducing method for aquatic biological water quality standard of a pyrethroid pesticide and a waterquality safety assessment method. When evaluating whether a certain water quality is safe or not, the water quality benchmark value for protecting aquatic organisms is obtained according to the aquatic organism water quality benchmark derivation procedure, and then the concentration value of such pollutants in the surface water source to be detected is detected. If the concentration value is lowerthan the water quality benchmark value, the water quality is safe, otherwise, the water quality is unsafe. The water quality reference derivation method provided by the invention is simple and has strong pertinence, and provides a theoretical basis for the environmental protection department to formulate the surface water quality standard for protecting pyrethroid pesticides.

Description

technical field [0001] The invention belongs to the technical field of water quality safety evaluation, and in particular relates to a water quality benchmark derivation method and a water quality safety evaluation method for pyrethroid pesticide aquatic organisms. Background technique [0002] The problem of surface water pollution is widespread around the world. With the urgent need for water resources and the gradual emphasis on environmental issues, the monitoring and management of surface water quality has always been the focus of scholars' research. Environmental quality assessment of surface water, as the key to managing surface water quality, is the top priority of research. When evaluating whether the water quality is safe, it is often necessary to judge whether the concentration of various pollutants contained in the evaluated water body is within the required limit. Therefore, quickly and accurately obtaining the safe concentrations of various pollutants in water...
