Understanding plastic degradation and microplastic formation in the environment: A review
This review covers how plastics break down in the environment through sunlight, heat, water, and microbial action to form microplastics smaller than 5 millimeters. The process depends on both the type of plastic and environmental conditions, but knowledge about real-world degradation rates and pathways is still limited. Understanding how microplastics form is essential for predicting where they accumulate and how they might enter the food chain and drinking water.

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.
Biodegradation of typical plastics and its mechanisms
This review summarizes the mechanisms by which common plastic types are broken down by bacteria, fungi, and other microorganisms in the environment.

Microplastics: From Intrinsic Properties to Environmental Fate
This review examines how the built-in properties of plastics — their chemical structure, additives, and molecular weight — determine how quickly they break down in the environment and what happens when they do. As microplastics degrade, they fragment into even smaller particles that may be more harmful because they can more easily enter living organisms. Understanding these degradation pathways is essential for predicting the long-term environmental and health risks of plastic pollution.
