Problems solved by technology

However, today's devices for collecting microplastics in the atmosphere still have deficiencies: the actual sampling operation requires long-term continuous sampling and monitoring, and the device is affected by wind and rain, and the samples will overflow from the device with rain or the wind will cause the samples to It cannot be accurately deposited into the device, which increases the difficulty of manual adoption. It is necessary to manually monitor the sampling according to the weather and lead to inaccurate sampling results, which will affect the evaluation results of atmospheric microplastics

Abstract

The invention relates to the technical field of environmental monitoring, in particular to an automatic collecting device for atmospheric settling micro-plastics and a using method thereof. The automatic collecting device structurally comprises a supporting frame, a sample collector is fixed to the supporting frame and comprises a sample receiving groove, the sample receiving groove comprises a groove body and a cylindrical-table blocking cover, and a groove opening of the groove body is vertically upward; the upper bottom surface and the lower bottom surface of the blocking cover are both openings, the blocking cover sleeves the peripheral side of the groove body, the opening of the lower bottom surface of the blocking cover is fixedly connected to the peripheral side of the groove body, the bottom area of the blocking cover is gradually enlarged from bottom to top, an inlet is formed in the peripheral side, close to the lower bottom surface of the blocking cover, of the groove body, the blocking cover is lower than the groove body, and filter holes are formed in the bottom of the groove body. And a filter membrane covering the filter holes is placed at the bottom of the groove body. The device is not affected by weather, can accurately collect micro-plastics in the atmosphere, and has the advantages of being simple in structure and easy to operate. The using method of the device can rapidly and accurately collect samples, and has the advantage of being easy to operate.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an automatic collection device for atmospheric deposition microplastics and a method for using the same. Background technique [0002] Microplastics (Microplastics) is a newly discovered organic pollutant, which has become one of the environmental issues of global concern, especially the problem of atmospheric microplastic pollution is a recent focus of attention. According to research, there are synthetic fibers, mixed fibers, natural polymers (rayon, cellulose acetate, etc.) and natural fibers (cotton, wool, etc.) in the atmosphere. An important source, microplastics that exist in the atmospheric environment will settle on land, and can also be transported to the ocean through the atmosphere, causing microplastic pollution on the earth's water surface. [0003] Atmospheric microplastic pollution will also directly cause harm to human health. Microplastics in ...
