Problems solved by technology

At present, there are many studies on harmful gases and some achievements have been made. The research on PM2.5 is still in-depth. Animals inject or ingest PM2.5 particles, which is against the normal behavior of animals
In addition, research on the mixed exposure of harmful gases and PM2.5, and the possible impact of changes in the temperature and humidity of the animal's living environment on exposure are currently rare reports

Embodiment

[0024] The system extracts natural air, and the airflow has temperature, humidity, air pressure, CO gas, SO 2 gas, NO 2 Gas, O 3The comprehensive control function of the eight climate and environmental factors of gas and aerosol particles, and then enter the artificial climate environment simulation exposure box or the artificial climate environment simulation control box for animal experiments. According to the operating conditions of the system, we have designed a total of 5 different combinations of operating modes for these eight climatic and environmental factors, which are single climate box, static, compensated static, dynamic low speed, and dynamic constant speed. Corresponding piping systems and equipment are designed for these operating modes. The operating conditions corresponding to these five operating modes are shown in Table 1, and the control process is detailed in image 3 (It can be realized by using software such as Labview).

Abstract

The invention discloses an artificial climate environment exposure system and an application method. The system includes aerosol collection and concentration, harmful gas mixing, temperature and humidity adjustment, exposure box and control box and various auxiliary equipment, providing an efficient and cumulative animal experiment suitable for aerosol particles and harmful gas exposure The environmental control system combines the collection of aerosol particles with multi-factor control of the warehouse-style artificial climate environment. The system is designed with a combination of various environmental factors, and has a variety of experimental functions to achieve the effect of one machine with multiple functions. It can be used not only to study the exposure of atmospheric suspended particles to animals, but also to study harmful gases and environmental climate factors. For the exposure effect of animals, the synergistic exposure effect of the three can also be studied.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an artificial climate environment exposure system and an application method. Background technique [0002] In recent years, environmental problems have become more and more serious, especially air pollution, which has attracted widespread attention from all walks of life. Today's air pollution in my country not only includes acid rain, photochemical and other harmful gases emitted by industrial or agricultural production. Smog, ozone depletion, etc., also include the increasingly serious haze weather, which is mainly caused by the significant increase in atmospheric aerosols, including the well-known PM2.5, which has a small particle size, large area, strong activity, and is easily Accompanied by toxic and harmful substances (such as heavy metals, microorganisms, etc.), it has a very bad impact on human health and the quality of the atmospheric environment. Consid...
