Microplastic content prediction in agricultural soils using a mixed variable selection combined with Transformer-LSTM fusion architecture
AI summary
This research developed pH-responsive chitosan-based food packaging materials with barrier properties and antimicrobial activity, characterizing the material's mechanical performance and degradation behavior. The study positions chitosan composites as functional alternatives to conventional plastic food packaging with added smart packaging capabilities.

Land use shapes the fate of soil microplastics in China: Insights from machine learning
AI summary Read the abstract
A massive study analyzing nearly 1,500 soil samples across China found that farmland, especially orchards and fields covered with plastic sheeting (mulch), had far more tiny plastic particles than forests or natural areas, with mulched fields showing about 6 times more contamination. Since these are the soils growing our food, this matters because it suggests the crops we eat may be absorbing more microplastics from heavily farmed, plastic-mulched land, highlighting a need for smarter farming practices to reduce this exposure.
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.
A Novel Approach for Fast Microplastic Quantification in Sediments Using Machine Learning—Spectrometer Combinations
AI summary Read the abstract
Researchers combined visible near-infrared and FTIR spectroscopy with machine learning models (SVR, PLSR, BPNN) to rapidly estimate concentrations of PE, PP, PS, and PVC microplastics in river and loess sediments without extraction or manual counting. Faster, non-destructive quantification methods are crucial for scaling up microplastic monitoring across diverse environmental matrices and enabling consistent cross-study comparisons of pollution levels.
Application of machine learning in assessing spatial distribution patterns of soil microplastics: a case study of the Bang Pakong Watershed, Thailand
