Abstract

The invention discloses a research device for the toxicological effect of pollutants on fish, which includes a box body, and the box body is provided with a raw material area, a mixing area, a diffusion area, a steady flow area, an exposure area and a water collection area along the direction of water flow. The exposure area described therein includes: a front water filter plate, a flow rate control plate, and a partition vertically arranged in the box, and the partition divides the exposure area into multiple side-by-side sub-exposure areas; the flow rate control plate is controlled by multiple independent And it is composed of sub-flow rate control plates corresponding to the corresponding sub-exposure areas, each sub-flow rate control plate includes a fixed plate and a moving plate that can move relative to the fixed plate, and the fixed plate and the moving plate are provided with water permeable holes at corresponding positions; Drive units connected to the mobile board. The present invention realizes the flow rate control of each sub-exposure area by setting the flow rate control board, which facilitates the study of the influence of pollutants on the toxicological action of fish under the change of flow rate; realizes the uniformity of water quality, and avoids the concentration difference of the exposed substances entering different sub-exposure areas. error.

Description

technical field [0001] The invention belongs to the field of ecotoxicology, and in particular relates to a research device for toxicological effects of pollutants on fish. Background technique [0002] Persistent Toxic Substances (PTS) refer to those pollutants that are persistent, bioaccumulative, long-distance environmental mobility, and toxic. There are many kinds of persistent toxic substances, including heavy metals and their compounds, inorganic non-metallic compounds, persistent organic pollutants, etc. It is difficult to eliminate persistent toxic pollution through purification, and there are also great differences in the pollution of different species by chemicals. Such substances will produce bioaccumulation effects in organisms, affect the normal maintenance of organisms, and can accumulate in the food chain, affecting organisms with higher trophic levels. Many PTS pollutants have a variety of acute and chronic toxicity, as well as "three causes" toxicity of ter...
