Microplastics as Pervasive Contaminants: Ecosystem Disruption, Human Health Risks, and Detection Approaches

Year: 2026

Type: article

Abstract: Microplastic (MP) contamination has become a global environmental and public health concern due to the extensive use of plastics and ineffective waste management. These microscopic particles are now detected in air, water, soil, and food products, raising serious concerns about their persistence, bioaccumulation, and potential risks. Microplastics (MPs) have been shown to disrupt marine biodiversity, affect plant metabolism, and enter food webs, leading to accumulation in human tissues. Chronic exposure is increasingly linked to reproductive toxicity, carcinogenesis, neurotoxicity, and metabolic disorders. This review provides a comprehensive overview of the sources, pathways, and environmental fate of microplastics, with an emphasis on their ecotoxicological effects and human health implications. It also summarises key analytical methods for detecting microplastics in environmental and food matrices, including spectroscopy, microscopy, and emerging sensor-based technologies. Finally, the review highlights the need for improved waste management, stronger policy interventions, and enhanced public awareness to mitigate microplastic pollution and protect ecosystem and human health.
