Environmental behaviors and degradation methods of microplastics in different environmental media
AI summary Read the abstract
This review summarizes the distribution of microplastics across soil and water environments and focuses on the various methods being developed to break them down, an area that has received relatively little research attention. Researchers found that understanding how microplastics move through different environments is essential for developing effective treatment strategies. The study highlights degradation approaches including biological, chemical, and physical methods while noting that significant knowledge gaps remain.
Microplastics, as a group of emerging contaminants, are widely present in environmental media and have the potential to endanger the ecological environment and human health. Due to the inconsistencies and difficulties inherent in the analysis of microplastic particles, global monitoring data on the distribution of microplastics in the environment are still far from sufficient. The fate and migration of microplastics in the environment are also uncertain. Therefore, there have been increasing reviews on the distribution, biological effects, migration, and health risks of microplastics. However, reports focusing on the degradation of microplastics are still rare. Understanding and commanding the environmental behavior of microplastics are of great significance to explore the treatment of microplastic pollution. Although some preliminary studies on microplastics have been carried out, there is still an urgent need to conduct a comprehensive study on environmental behaviors and degradation methods of microplastics in different environmental media. This article summarizes the recent advances on microplastics, basically includes the distribution and ecological impact of microplastics in soil and water environments, then elaborates the migration behavior and influencing factors of microplastics, and focuses on the research progress of microplastics degradation methods. On this basis, the problems existing in the current research and the future development directions have been proposed. This review could provide a more systematic reference for the development and research of microplastics in the future.

A critical review on occurrence, distribution, environmental impacts and biodegradation of microplastics
AI summary Read the abstract
This review provides a broad overview of microplastic pollution, covering where these particles come from, how they spread through terrestrial and aquatic environments, and their effects on ecosystems. Researchers found that microplastics are now present in virtually every environment studied worldwide, from deep oceans to mountain soils.

Removal technologies of microplastics in soil and water environments: review on sources, ecotoxicity, and removal technologies
AI summary Read the abstract
This review covers the sources, toxic effects, and removal methods for microplastics in both soil and water environments. The authors found that while various treatment technologies exist, most are still in early stages and preventing microplastics from entering the environment in the first place may be more practical than trying to clean them up afterward. The review also notes that far fewer studies have examined microplastic toxicity in soil organisms compared to aquatic species, leaving a significant knowledge gap.
Current Progress and Mechanisms of Microplastic Degradation in the Environment
AI summary Read the abstract
This review pulls together current research on how tiny plastic bits called microplastics—which are now found in our food, water, air, and soil—can be broken down before they build up further in the environment. These plastic fragments can soak up heavy metals and other toxic chemicals, making them even more dangerous as they move through the food chain and potentially into our bodies. Understanding how to break them down more effectively could help scientists and policymakers develop better strategies to cut down on this pollution and reduce our exposure to it.
