Abstract

The invention provides a system for synchronously collecting multi-particle size microplastic samples in water bodies of different depths. The system comprises a floater, a sinker and a vertical fracture surface connecting rope, wherein the floater is installed at an upper end of the vertical fracture surface connecting rope, the sinker is installed at a lower end of the vertical fracture surfaceconnecting rope, a plurality of microplastic sample collectors are uniformly distributed on the vertical fracture surface connecting rope, the microplastic sample collectors comprise active collectorsand passive collectors and are fixedly installed on the vertical fracture surface connecting rope through collector fixing parts, the upper end of the vertical fracture surface connecting rope is provided with a dragging rope, the other end of the dragging rope is installed on a dragging ship, and the dragging rope can be used for guaranteeing that the vertical fracture surface connecting rope keeps a vertical state during sampling. When used for collecting samples, the system can be used for synchronously collecting the microplastic samples of different depths and different particle sizes, the collection efficiency is improved, and the collection time is shortened.

Description

technical field [0001] The invention relates to the technical field of environmental pollution monitoring equipment, in particular to a synchronous collection system for multi-particle diameter microplastic samples in water bodies of different depths. Background technique [0002] Microplastics (Microplastics) refer to plastic particles with a diameter of no more than 5 mm, which has become one of the hot issues of international concern. In 2014, the first United Nations Environment Assembly (UNEP1) listed microplastic pollution as one of the top ten global environmental problems to be solved for the first time. In 2015, UNEP2 listed marine microplastics as the second largest scientific issue in the field of environmental and ecological science research, and ranked it with global climate change, ozone depletion and ocean acidification as a major global environmental issue of common concern to scientists around the world. [0003] Microplastics in water bodies mainly come fr...
