Advances in Resources and Environmental Science

This article explains the multiple dimensions of microplastic pollution, including its definition, characteristics, roots, environmental dispersion, impact on the ecosystem, and response strategies. Microplastic pollution, as a global environmental problem, is defined as plastic particles less than 5 mm in diameter, which can be subdivided into primary microplastics and secondary microplastics. It comes from a wide range of sources, covering daily life habits, industrial manufacturing processes and agricultural activities. The widespread presence of microplastics in nature, especially their distribution in water, soil and atmosphere, poses a severe challenge to the ecosystem, especially the significant impact on aquatic and terrestrial ecosystems, and also poses a potential hazard to human health. . Strategies to address this issue range from reducing emissions at source, strengthening monitoring and evaluation to developing efficient cleanup and recycling technologies. International cooperation and policy guidance play an irreplaceable role in the control of microplastic pollution. At the same time, raising public awareness of microplastic pollution and advocating a green lifestyle are also important ways to alleviate this problem. In the future, the scientific research community will focus on the study of the accumulation mechanism and toxic effects of microplastics in organisms, as well as the in-depth exploration of how microplastics affect global climate change.
