Microplastics and nanoplastics (MNPs) are a significant concern in aquatic environments, affecting biota as complex mixtures. However, the consequences of environmentally realistic MNPs exposures are poorly understood, and suitable data for high-quality risk assessments are limited. Most field research and toxicity testing has focused on micron size ranges, leaving knowledge gaps in understanding smaller nanoplastics (< 1µm). Furthermore, to quantify the scale of MNP effects, a broader approach is needed, considering plastics complexity and other environmental stressors, such as climate change. This session’s goal was to discuss MNPs effects assessment under a broader framework to provide suitable data for improved risk assessments. |
