Problems solved by technology

[0006] Due to the complex, delicate and special technical requirements mentioned above, there is no equipment or device that meets the requirements on the market. The existing experimental methods are not only inefficient, but also difficult to meet the testing requirements of unstable "difficult substances" and chronic Toxicity, environmental endocrine disrupting water ecotoxicity long-term research needs
This brings greater difficulties and errors to chemical substance testing and scientific research

Abstract

The invention discloses a water environmental factor monitoring experimental device based on water flea toxicity. The water environmental factor monitoring experimental device based on the water fleatoxicity comprises a water flea culture container (1), an environmental culture liquid preparation unit (2), an environmental culture liquid storage and distribution unit (3), an environmental cultureliquid supply and delivery unit (4), and a waste liquid processing unit (5); the water flea culture container (1), the environmental culture liquid preparation unit (2), the environmental culture liquid storage and distribution unit (3), and the environmental culture liquid supply and delivery unit (4) are connected separately through the environmental culture liquid supply and delivery unit (4);and the water flea culture container (1) is connected to the waste liquid processing unit (5). The water environmental factor monitoring experimental device based on the water flea toxicity disclosedby the invention has simple structure and reasonable design, which can accurately simulate the monitoring of water environment factors based on the water flea toxicity, and provides a reliable basisfor experimental research.

Description

technical field [0001] The invention relates to the technical field of environmental water quality monitoring, in particular to an experimental device for monitoring water body environmental factors based on the toxicity of Daphnia magna. Background technique [0002] The rapid development of industrialization and urbanization has produced a large amount of industrial and domestic sewage. Wastewater contains various types of pollutants, and its toxic effects are worthy of attention. [0003] Daphnia magna, also known as water fleas or scratches, is commonly known as red worms or fish worms, and belongs to Cladocera (Cladocera), which refers to animals of the phylum Arthropoda, Crustacea, Branchopods, Dimorpha, and Cladocera. As a model organism for environmental pollution monitoring, Daphnia magna has great scientific research value and plays an important role in testing the acute and chronic toxicity of pesticides and chemicals and the effects of environmental hormones. ...
