Embodiment Construction

[0063] Definitions of technical terms:

[0064] Water quality benchmark: The maximum dose or level of pollutants or harmful factors in the water environment that will not have harmful effects on human health and aquatic ecosystems.

[0065] Estuary: An estuary is the terminal point of a river, that is, the confluence area of ​​the river and the ocean, lake or other rivers; the estuary referred to in the present invention is the confluence area of ​​the river and the ocean, that is, the estuary into the sea.

[0066] Estuarine aquatic organisms water quality standard, EWQCsp: Water quality standard that can protect estuary aquatic organisms and their ecological functions, including estuary aquatic organisms water quality standard high value and water quality standard low value.

[0067] Estuarine aquatic organisms water quality benchmark high value, HEWQCsp: Water quality benchmark that can protect estuary aquatic organisms and their ecological functions under short-term exposu...

Abstract

The invention provides a method for obtaining a water quality standard of estuary aquatic organisms. The method comprises the following steps: firstly, obtaining priority control pollutants and commonpollutants in a scoring manner; after determination of contaminants, aiming at the pollutant screening estuary tested biological species, providing the tested species screening method suitable for the estuary region, and preliminarily determining the estuary water quality reference tested biological recommendation list according to the relationship between the sensitivity of different species andthe cumulative probability of main pollutants, wherein the list is different from the species in fresh water and seawater; after the tested biological species are determined, providing a toxicity data collection and screening principle suitable for the estuary environment of China; after toxicity data is obtained, adopting a species sensitivity distribution method to derive a reference thresholdvalue. Five models are adopted to be used for toxicity data fitting, corresponding evaluation criteria are provided, a model most suitable for the pollutant can be selected according to the evaluationcriteria, and therefore the more accurate reference threshold value is obtained.

Description

technical field [0001] The invention relates to the technical field of water quality benchmarks, in particular to a method for determining the water quality benchmark threshold value of estuary aquatic organisms. Background technique [0002] Water Quality Criteria (Water Quality Criteria) is the basic work and reference index for the formulation of water quality standards. Since my country's water quality standards were initially established with reference to the water quality standards of foreign countries and world organizations, and did not carry out their own water quality benchmark research based on my country's national conditions, the existing water quality standards cannot truly reflect the needs of water environmental protection, resulting in my country's environmental protection. There are "underprotection" and "overprotection" problems. "Under-protection" may cause harm to human health or the ecological system. Although "over-protection" will not endanger the eco...
