Height-adjustable portable atmospheric micro-plastic collecting device and using method thereof

Abstract

The invention discloses a height-adjustable portable atmospheric micro-plastic collecting device and a using method thereof. The using method of the device is easy to operate, all parts are detachable, foldable and telescopic, and the device is convenient to carry during field sampling; the device is easily available in material, simple in structure and easy for large-scale production. According to the invention, the sampling height can be adjusted by using the telescopic rod with the scales. The device does not need electricity, is suitable for various sampling environments, and ensures that the device can settle and collect micro-plastics in the atmosphere for a long time. The adjustable supporting frame and the levelness measuring element on the connecting plate are used for measurement, the connector below the connecting plate is used for adjusting the horizontal state of the sampling device, measurement errors caused by uneven horizontal placement are avoided, and the accuracy of later experiment results is improved. The tank body is arranged in the sampler, and micro-plastics can be smoothly gathered on the filter membrane at the bottom of the tank body through the inlet in the tank body, so that experimental materials are saved, and the sampling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of detection and application of microplastics, and in particular relates to a height-adjustable portable atmospheric microplastic collection device and a method for using the same. Background technique [0002] Microplastics (MPs) generally refer to plastic particles with a particle size of less than 5 mm. Compared with macroplastic fragments, microplastics are more hazardous due to their high abundance, small particle size, and ability to be transported over long distances. On the one hand, microplastics can act as carriers for the migration of various pollutants in environmental media; on the other hand, the leakage of microplastics themselves will also cause pollution to the environment. At present, most of the research on microplastics in academia is concentrated in the marine and lake water environment, and the research on microplastics in the atmospheric environment is relatively lacking. The atmosph...
