ClearSystematic Review of Degradation Processes for Microplastics: Progress and Prospects
This systematic review summarizes existing research on different methods for breaking down microplastics, including photodegradation, chemical oxidation, and biological approaches. The study evaluates how effective each technique is at destroying microplastics and discusses which methods show the most promise for real-world application. Finding effective ways to degrade microplastics is critical because these particles persist in the environment for hundreds of years and continue to enter our food and water.

The findings provide a comprehensive overview of physical and chemical detection techniques, helping advance efforts to clean up microplastic contamination that ultimately affects the water we drink and the food we eat.
A critical review on occurrence, distribution, environmental impacts and biodegradation of microplastics
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. The study highlights biodegradation by microorganisms as a promising but still underdeveloped approach for addressing microplastic contamination.
Detection and degradation of microplastics in the environment: a review
This review covers methods for detecting and breaking down microplastics in the environment. Microplastics persist in ecosystems and pose potential risks to both human health and wildlife. The paper highlights the need for better tools and strategies to address this growing pollution problem.
Challenges and Strategies for Degradation of Microplastics in Environment
This review examines the challenges of degrading microplastics in environmental settings, discussing their hydrophobic nature, persistent covalent bonds, and large specific surface area that attracts co-contaminants, and surveys physical, chemical, and biological degradation strategies alongside remaining technical hurdles to practical implementation.
Environmental behaviors and degradation methods of microplastics in different environmental media
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.
Bioremediation of microplastics in freshwater environments: A systematic review of biofilm culture, degradation mechanisms, and analytical methods
This review summarizes existing research on using natural biofilms — communities of microorganisms — to break down microplastics in freshwater. Certain bacteria can degrade plastic particles, offering a potential eco-friendly cleanup method. While the approach is still slow and not yet widely practical, it points toward biological solutions for reducing microplastic pollution in our water supply.
Environmental fate, aging, toxicity and potential remediation strategies of microplastics in soil environment: Current progress and future perspectives
This review summarizes what we know about microplastics in soil, including where they come from, how they age and break down, and their toxic effects. As microplastics degrade in the environment, they can release harmful chemicals and help transport other pollutants like heavy metals through the food chain to humans. The paper also explores cleanup strategies, though effective large-scale solutions remain a challenge.
A review of biodegradation and formation of biodegradable microplastics in soil and freshwater environments
Researchers reviewed how biodegradable plastics break down in soil and freshwater, finding that incomplete degradation by microorganisms can still produce tiny biodegradable microplastic particles that persist in the environment — meaning "biodegradable" doesn't always mean safe or fast-disappearing.
Occurrence, impact, toxicity, and degradation methods of microplastics in environment—a review
This review summarizes current knowledge about microplastic pollution, covering where these particles come from, how they affect ecosystems, their toxic effects on organisms, and methods for breaking them down.

The study examines physical, chemical, and biological degradation methods as potential tools for addressing microplastic contamination.
Unravelling the ecological ramifications of biodegradable microplastics in soil environment: A systematic review
Researchers reviewed 85 studies on biodegradable microplastics in soil, finding that when biodegradable plastics fail to fully break down they can disrupt soil structure, nutrient cycling, and microbial life in ways that depend heavily on concentration and plastic type. The review highlights that "biodegradable" plastics are not a simple fix for microplastic pollution in agricultural soils.
Potential environmental impacts of bioplastic degradation in natural marine environments: A comprehensive review
This review examines the environmental impacts of biodegradable plastics degrading in marine environments, finding that their microscale breakdown raises significant concerns about contributing to microplastic pollution rather than eliminating it. The authors conclude that biodegradable plastics require reevaluation as petroleum-based plastic substitutes given the incomplete understanding of their behavior at the microscale in marine ecosystems.
Challenges and opportunities in bioremediation of micro-nano plastics: A review.
This review examines biological approaches to removing micro- and nanoplastics from the environment, focusing on microbial degradation and bioremediation strategies.

The study highlights that while microplastics are now found in virtually every environmental niche, biological approaches to breaking them down are still in early stages of development.
Microplastics and nanoplastics: Source, behavior, remediation, and multi-level environmental impact
This review summarizes existing research on where microplastics and nanoplastics come from, how they move through air, water, and soil, and their toxic effects on living organisms from marine life to humans. Once ingested, these particles accumulate in the body over time through a process called bioaccumulation and can become more concentrated as they move up the food chain. The authors highlight that effectively addressing plastic pollution will require combining cleanup technologies with strong regulatory policies.
Degradation of microplastics in the natural environment: A comprehensive review on process, mechanism, influencing factor and leaching behavior
This review examines how microplastics break down in the environment through physical, chemical, and biological processes, and what happens as they degrade. As microplastics age and fragment, they release chemical additives and dissolved organic matter that can be toxic, meaning degrading plastics may actually become more harmful to ecosystems and human health over time.
Microplastic accumulation in soils: Unlocking the mechanism and biodegradation pathway
Researchers reviewed how microplastics accumulate in soil and break down biologically, finding that certain microorganisms can form biofilms on plastic surfaces and use enzymes to slowly degrade the polymers — though conditions like pH, temperature, and moisture must be optimized and new plastic-degrading microbes need to be identified before this approach can be widely applied.
