Abstract

The invention relates to the technical field of micro-plastic detection, in particular to a device and method for detecting micro-plastic in air, and the device comprises an environmental data monitoring module, an atmosphere sample collection module, a sample processing module and a controller; the environmental data monitoring module comprises a plurality of environment monitoring sensors used for detecting environment data, and the output ends of the environment monitoring sensors are connected with the input end of the controller. The output end of the controller is connected with the input end of the atmosphere sample collection module and is used for controlling the atmosphere sample collection module to work for sample collection, and the output end of the controller is connected with the input end of the sample processing module and is used for controlling the sample processing module to preprocess a sample. The device for detecting the micro-plastics in the air can realize selective sampling of the atmosphere so as to obtain a required atmosphere sample, and meanwhile, the micro-plastic particles can be classified and screened, so that the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of microplastic detection, in particular to a device and method for detecting microplastics in the air. Background technique [0002] Microplastics usually refer to plastic fibers, particles or films with a particle size of less than 5mm, and are mainly divided into primary microplastics and secondary microplastics. Microplastic pollution is ubiquitous in salt, seafood, takeaway food, and bottled water. Household life, such as washing clothes and using toiletries, will also emit a large amount of microplastics. The migration, transformation, fate and ecological toxicity of microplastics in the environment Physiological effects have attracted much attention. Existing relevant research mainly focuses on microplastic pollution in ocean and nearshore water bodies and sediments. The latest research has found that microplastics also exist in the atmosphere and glaciers in remote areas, and the globalization trend...
