A Critical Evaluation of Nano‐ and Microplastics: Sources, Health Risks, and Mitigation Strategies
Microplastics (1 μm–5 mm) and nanoplastics (< 1 μm) have become ubiquitous contaminants across air, water, and soil systems, with growing evidence of their presence in human tissues including blood, lungs, and even the placenta. While microplastics have been extensively studied, nanoplastics remain poorly understood because of their minute size and ...
