A Machine-Learning Model for Investigating Microplastics Source–Receptor Relationships in Aquatic Environments
AI summary Read the abstract
Researchers developed a machine-learning model to trace where microplastics in aquatic environments come from and where they end up, potentially giving scientists and regulators a more powerful tool to identify pollution sources and prioritize cleanup efforts.
Due to its durability, low manufacturing cost, and versatility, plastic is a highly desirable product, and its production has been increasing over time. As such, the presence of plastic pollution in our environment also continues to increase. Plastic pollutants are...

Microplastics in aquatic environments: Bridging occurrence and mitigation through machine learning detection and bioremediation strategies
AI summary Read the abstract
Tiny plastic particles called microplastics are showing up in shockingly high amounts in our water, sometimes millions of particles per liter, and they can end up affecting both aquatic life and, potentially, the food and water we consume. This review paper (summarizing existing research) highlights two promising solutions: certain fungi and algae that can remove over 90% of microplastics from water in lab settings, and AI tools that can quickly detect and track plastic pollution. The catch is that these cleanup methods work great in controlled settings but haven't yet been proven to work reliably in messy, real-world water systems.
Machine Learning Approaches for Predicting Microplastic Removal
AI summary Read the abstract
Researchers applied Bayesian optimization combined with machine learning models — including boosted regression trees, neural networks, and support vector regression — to predict microplastic removal during coagulation, finding the BOA-BRT hybrid outperformed conventional methods by up to 71%, with microplastic particle size identified as the most influential variable.
Predicting microplastic impacts on microalgae: A machine learning approach to understand dynamic interactions in aquatic ecosystems
AI summary Read the abstract
Scientists used artificial intelligence to figure out how microplastic pollution harms microalgae, tiny organisms that form the base of the food chain in oceans and lakes and produce much of the oxygen we breathe. They found that temperature and the plastic's chemical properties (like particle size and charge) play the biggest role in how much damage occurs, with water temperature mattering most early on and plastic characteristics mattering more over time. This matters because microalgae support entire aquatic food webs (including the fish we eat), so understanding what makes microplastics most harmful can help guide better pollution control to protect both ecosystems and our food sup
Tracing the Sources of Microplastics in Aquatic Environments: Current Knowledge of Sources Emission, Migration, and Traceability Models
AI summary Read the abstract
Researchers reviewed how microplastics enter aquatic environments from terrestrial and atmospheric sources, and how traceability models have evolved from subjective analysis to data-driven machine learning approaches that can identify pollution sources by learning relationships between microplastic characteristics and environmental variables.
Integration of bio-inspired algorithms with machine learning for modeling microplastic contamination transport processes in natural aquatic habitats using morphological features
AI summary Read the abstract
Scientists built a computer model that can accurately predict how microplastic particles move through rivers, lakes, and oceans based on their shape and size. This matters because understanding where these tiny plastic bits travel and accumulate, including in water sources we may eventually drink or in seafood we eat, can help authorities track pollution hotspots and create smarter policies to keep our water supplies cleaner.
