Critical gaps in nanoplastics research and their connection to risk assessment
This paper identifies critical knowledge gaps in nanoplastics research and explains why they matter for assessing health and environmental risks. Nanoplastics are harder to detect and measure than larger microplastics, meaning current pollution estimates likely undercount total plastic contamination. The authors call for better detection methods and standardized research approaches to understand the true scope of nanoplastic exposure.
