“…1. The average diameters of the single fibres for three outer layers were 24 3.6 µm, similar to the internal layers (23-28 µm) [5]. In conclusion, although collecting discarded masks will have some economic losses, the government should not give up the measure since the effect is long-lasting and devastating.…”

Due to the global pandemic, we are producing a large number of discarded masks every day. At the same time, some of them will find their way into the ocean and affect the Marine ecology. This paper will analyze the damage of waste masks to the ocean, and give solutions for reference. Through case analysis, this paper concludes that waste masks have brought certain impacts on various Marine organisms and destroyed the stability of Marine ecosystems, but there are still some solutions to improve the problem. This article will provide solutions that can be adopted by governments today, as well as some directions and goals that can be developed in the future. In the future, we can better protect the Marine ecology and pay attention to environmental protection although there will be some cost burden for the government. To protect animals while improving the overall environment of the earth on which human live.

“…Compared with other polymers, PP is prone to aging and undergoes degradation and oxidization only under harsh environmental conditions to yield carboxyl/hydroxyl groups upon exposure to sunlight, heat, oxidants, air, and humidity, 303 which consequently alters its reactivity. 42 The aging of PP results in increased crystallinity, formation of surface cracks, and embrittlement.…”

“…With the growth of the plastic industry all over the world, plastic pollution in the environment has drawn much attention [1][2][3]. Currently, plastic debris is widely found in the ocean [4,5], freshwater [1,6], sewage [7], sediments [8], and aquatic organisms [9]. Increasing amounts of plastic in water have pronounced effects on freshwater ecology and societal services, as increasing plastic pollution may have toxic effects on aquatic organisms [10], alter aquatic species composition [11], and increase the cost of drinking water purification [12].…”

Microplastic (MP) pollution is a rapidly spreading global problem, threatening the use and sustainability of freshwater resources. MPs in water can act as both a source and sink of dissolved organic compounds. This review summarizes the current knowledge of interactions between MPs and dissolved organic compounds, including the adsorption and release of dissolved organic compounds by MPs and the impacts of MPs on the source and sink of natural dissolved organic matter (DOM) in aquatic ecosystems. The key mechanisms for the adsorption of dissolved organic compounds on MPs are hydrophobic interactions, van der Waals forces, and π–π interactions. Particle size, morphological characteristics, density, and environmental factors (pH, ionic strength, and UV radiation) have a great influence on the adsorption of dissolved organic compounds on MPs. Although research on the interactions between dissolved organic compounds and MPs has progressed rapidly, to date, research on the impacts of increasing amounts of MPs on natural DOM cycles (production, transformation, and fate) in aquatic ecosystems has been very limited. Knowledge gaps and future research directions are outlined at the end of this review.
