AI Summary (NQ-processed)
A research group at Tokyo University of Science has developed a method to approximate the size spectrum of microplastics (MP) in rivers using a power-law model, enabling high-precision estimation of mass concentration including unmeasured sizes from limited observed size ranges. This resolves difficulties in comparing studies with different size ranges and allows unified assessment of MP pollution.
