Summary

Researchers analyzed the horizontal and vertical distribution of microplastics at different water depths across Gehu Lake in China, finding microplastics present throughout all depth layers with surface water showing the highest abundance (3.13 plus or minus 0.32 items/L) and bottom water the lowest (1.03 plus or minus 0.14 items/L). They found that most microplastic particles ranged from 100 to 500 micrometers in size with fibrous shapes predominating, and identified polyethylene terephthalate and polypropylene as the main polymer types in the lake.

Abstract Microplastics (MPs) widely exist in the aquatic environment. In this study, the horizontal and vertical distribution of MPs in different depths of Gehu Lake was analyzed. The study found that MPs were detected in water bodies at different depths. The Gehu Lake Basin's MP abundance throughout the entire lake region ranged from 1.40 to 5.53 n/L. Microplastic abundance in surface water (3.13 ± 0.32 n/L) was highest, and the average abundance of MPs in the middle water (2.28 ± 0.24 n/L) and bottom water (1.03 ± 0.14 n/L) was appreciably reduced (p &lt; 0.05). The microplastics observed in water samples were analyzed, and it was found that the particle size of most of the obtained microplastic particles was between 100 and 500 microns, the main shape was fibrous MP, and the MP content of transparent color was highest, and the four most common MPs was polyethylene (PE), polystyrene, polyester (PES), and polypropylene (PP). In this article, we emphasize the importance of comprehending the specific distribution characteristics of MPs in Gehu Lake. It provides a data foundation for future monitoring of MPs present in Gehu Lake, provides scientific and technological support for the assessment and prevention of microplastic pollution in this area, and offers some assistance for future lake water quality regulation.
