Researchers at Canada's University of Toronto (U of T) have proposed a new machine learning method to accelerate the counting and classification of microplastics, while also boosting affordability and ease of use.

U of T's Elodie Passeport said she, Shuyao Tan, and Joshua Taylor "established a prediction model that employs a trained algorithm that can estimate microplastic counts from aggregate mass measurements."

Passeport explained the model "has guaranteed error-tracking properties with similar results to manual counting, but it's less costly and faster, allowing for the analysis of multiple samples from multiple points to estimate microplastic pollution."

The researchers found the method enables manual processing with just a fraction of collected samples, while algorithmically predicting the quantity of remaining samples without additional error or variance.
