Prediction of Microplastic Removal Behavior via Gaussian Process Regression Based Residual Correction of a Reaction Kinetic Model
AI summary Read the abstract
Scientists are using a special technology called low-temperature plasma (a zap of energized gas) to break down microplastics, and this study built a math model to predict exactly how well it will work under different power levels and treatment times. The model didn't just describe past results—it accurately predicted outcomes in new, untested conditions, helping researchers figure out the fastest, most energy-efficient way to destroy microplastics. This matters because it could speed up the development of practical, real-world tools to remove these tiny pollutants—which have been found in human blood, lungs, and organs—from water and the environment.
Low-temperature plasma technology has recently gained increasing attention as a promising approach for microplastic degradation. However, most previous studies have primarily focused on removal efficiency and byproduct analysis, with limited emphasis on quantitative prediction of removal behavior. In this study, we proposed a predictive model combining reaction kinetics and Gaussian process regression to describe microplastic removal behavior under varying power and treatment time conditions. The proposed model accurately reproduced the experimental removal behavior and demonstrated reliable predictive capability in untrained power and time domains. Furthermore, the model was used to identify favorable operating conditions for achieving rapid microplastic removal with high energy yield. These findings suggest that the kinetics–Gaussian process regression model can serve as a useful tool for predicting low-temperature plasma-based microplastic removal behavior and for optimizing process operating conditions.

Machine learning modeling of microplastics removal by coagulation in water and wastewater treatment
AI summary Read the abstract
Researchers developed machine learning models to predict how effectively coagulation, a common water treatment process, can remove microplastics under different conditions. The best model achieved 96% accuracy and found that water temperature had the biggest negative effect on removal, while adding coagulant aids had the most positive effect. These tools could help water treatment plants optimize their processes to better remove microplastics from drinking water.
Geometry-Driven Prediction of Microplastic Transport in Saturated Sediments: Fast and Memory-Efficient Pore-Scale Modeling
AI summary Read the abstract
Scientists developed a new computer model that can predict how fast tiny plastic particles move through soil and sediment when water flows through them. This matters because microplastics can carry harmful chemicals like pesticides and heavy metals as they travel underground, potentially contaminating drinking water sources and groundwater. The model helps researchers understand where these plastic pollutants might end up and how quickly they could reach water supplies that people depend on.

Scientists tested AI models that predict whether tiny plastic and metal particles clump together or stay floating in water, which affects how far pollutants like microplastics travel and whether water treatment can remove them. The models worked reasonably well for familiar situations but struggled to predict behavior in new, untested conditions, showing more research is needed before relying on these tools for real-world environmental safety decisions.

Integrating structure and experimental data annotations with computational modeling framework for predicting micro-nanoplastics toxicities
AI summary Read the abstract
Scientists have created a computer-based method to predict how toxic tiny plastic particles (microplastics and nanoplastics) might be to our cells, without needing to run slow, expensive lab experiments for every single type of plastic. By teaching computer models to recognize patterns based on a plastic particle's shape and size, researchers can now screen many more plastic types for potential health risks than traditional testing allows. This matters because it could speed up our understanding of which plastics pose the greatest danger as they build up in our environment and bodies.
