Microplastic Pollution in Aquaculture: Challenges and Mitigation

Water and Environment Journal, EarlyView.
ABSTRACT Microplastics (MPs) have gained significant attention due to their potential environmental threat. This paper addresses MPs contamination in aquaculture, a critical concern for food safety and public health. The extensive use and disposal of plastic products in aquaculture, like netting materials, pose a significant threat to aquatic life ...
