Embodiment 1

[0024] Step 1. Collection, analysis and screening of toxicity data NOED

[0025] Collect methylmercury toxicity data NOED based on aquatic organisms, and analyze and screen the collected data in accordance with internationally recognized toxicity data screening principles. For example, toxicity data screening follows the following principles: (1) Toxicology tests should be based on international (2) Various water quality factors, such as temperature, pH, hardness, pollutant concentration, etc., should be regularly monitored during the test; (3) Acute toxicity tests give priority to the most sensitive life stages of the tested organisms, and there are When testing the toxicity data of multiple life stages of organisms, select the toxicity data of the most sensitive life stage; (4) There are various toxicity endpoints in the toxicity data, and the most sensitive indicators are given priority as the toxicity endpoint; Organisms with relatively high concentrations of compounds to ...

Abstract

The invention belongs to the technical field of water quality protection, and particularly relates to a determining method for an aquatic organism protection water quality standard of a bioaccumulation substance. The method includes the following steps of collecting and screening toxicity data NOED; obtaining the optimal fitted equation through fitting; obtaining a reference value BTC based on tissue through the optimal fitted equation; obtaining an aquatic organism protection water quality criteria WQC of the bioaccumulation substance; obtaining predicted environment concentration PEC; determining the aquatic organism protection water quality standard WQS of the bioaccumulation substance. The aquatic organism protection water quality standard WQS of the bioaccumulation substance can be scientifically determined, the aquatic ecosystem of China can be protected more scientifically, and a new thought and method are provided for formulating the water quality standard in China.

Description

technical field [0001] The invention belongs to the technical field of water quality protection, and in particular relates to a method for determining water quality standards for protecting aquatic organisms from bioaccumulative substances. Background technique [0002] As an important criterion of my country's water environment management, water quality standards are an important research work in the field of environment in my country at this stage. Scientific determination of water quality standards can provide a basic basis for my country's water environment management, protect the health and stability of my country's water ecosystem, and contribute to the smooth advancement of ecological civilization construction. Water quality standards for protecting aquatic organisms are an important part of my country's water quality standard system. How to scientifically determine water quality standards for aquatic organisms has gradually attracted the attention of domestic environ...
