Embodiment Construction
[0026] The monitoring objects were selected in the Jiaozhou Bay breeding area of Qingdao City, and were divided into three groups according to the individual size: large, medium and small, with 20 samples in each group. The shell lengths of large, medium and small individual groups were (12±0.5) cm, (9±0.3) cm, and 7.5±0.2) cm, respectively. Put three groups of mussels into the same water body environment at the same time, add pollutants from low concentration to high concentration (petroleum pollutants, heavy metal pollution and organophosphorus pesticides) to the water body, record the behavioral responses of the three groups of mussels, choose The most sensitive group of mussels was used as the monitoring object. The monitoring objects selected in the following experiments were selected according to the results of this experiment. In each experiment, 24 live mussels with similar individuals were selected as the monitoring objects.
[0027] Such as Figure 1-5 As shown, a...

The invention belongs to the technical field of marine water toxicity monitoring and discloses marine water toxicity biological monitoring equipment based on a binocular vision technology. The equipment comprises a binocular camera holder, a binocular camera set installed on the binocular camera holder, a mussel activity observation system, a slide rail for connecting the camera holder and the mussel activity observation system, a visual signal processing operation circuit, a watertight cable for connecting the binocular camera holder and the visual signal processing operation circuit, and a computer which is connected to the visual signal processing operation circuit and can send out instructions and output results. The equipment has a simple structure, is convenient to replace mussel living bodies, has high resolution and high measurement accuracy, has no influence on activity of living organisms, and has high reliability.
Description
technical field [0001] The invention relates to marine water quality toxicity biological monitoring, in particular to a marine water quality toxic biological monitoring device based on binocular vision technology. Background technique [0002] With the development of modern industry, a large number of toxic and harmful substances are directly discharged into the water and flow into the sea, which has a great impact on the marine environment and its ecosystem. However, the pollution components in the marine environment are complex, and various molecules and ions participate in various interactions (such as synergy, antagonism, additive effects, etc.) at the same time, and the toxicity of pollutants is also affected by environmental factors such as acid-base environment, water temperature, etc. Ecotoxic effects produce many unconventional responses. After these chemicals enter the environment, they will undergo a series of chemical reaction processes such as degradation, tran...
