Integrated experiment platform for evaluating chemical contamination biological effect in outdoor air

Abstract

The present invention discloses an integrated experiment platform for evaluating the chemical contamination biological effect in outdoor air, and belongs to the field of air chemical contamination monitoring. The apparatus comprises a gas flow generation system, a chemical contamination generation system, an animal sample testing system and an electronic control system. The apparatus is used for testing the biological reaction caused by diffusion of the chemical contamination along with the air so as to provide the experiment platform for effective research on the influence of the chemical contamination on the biomechanism and the harm degree of the chemical contamination on the animal. According to the present invention, the important practical significance is provided for the environment science research and the risk management.

Description

technical field [0001] The invention relates to an integrated experimental platform for evaluating the biological effects of chemical pollution in outdoor air, belonging to the field of air chemical pollution monitoring. Background technique [0002] As the number of chemical reagents used in the world increases year by year, the air pollution caused by chemical reagents shows a trend of intensification, and the level of chemical reagents in the air will cause risks to animals (such as insects) living in the atmosphere How to release chemical reagents quantitatively, how to simulate the outdoor aerosol flow field environment, and how to effectively collect and observe animal Samples are particularly important in evaluating the impact of chemical reagents drifting in the air on animal biology and risk management. [0003] At present, for research purposes, some universities or research institutions at home and abroad use a Peet-Grady chamber or an animal experiment box impro...

Problems solved by technology

[0003] At present, for research purposes, some universities or research institutions at home and abroad use a Peet-Grady chamber or an animal experiment box improved on this basis. These devices are ideal platforms for static animal poisoning threshold tests, but as dynamic, simulated When the platform for animal reaction in the outdoor environment, there will be shortcomings such as uneven flow field and poor comparability, such as "A Small Animal Gas Experimental Box" (patent application number is 200620136476.9) and "Animal Experimental Box" (patent application number is 200920154593.1), the attempts of these devices have promoted the development of the research on the characteristics and mechanism of animal biological effects, but these devices have their corresponding deficiencies. The more prominent problem is that the distribution of chemical pollution in the box is uneven, and the collected samples represent Poor performance, not suitable for animal biological sample collection and follow-up research when simulating outdoor chemical pollution environment changes
