Micro- and nanoplastic (MNP) pollution is a significant concern for ecosystems worldwide. The continuous generation extensive utilization of synthetic plastics have led to the widespread contamination water food resources with MNPs. These pollutants originate from daily-use products industrial waste. Remediation such essential protect human health since these ubiquitous contaminants pose serious biological environmental hazards by contaminating chains, sources, air. Various remediation techniques, including physical, chemical, sophisticated filtration, microbial bioremediation, adsorption employing novel materials, provide encouraging avenues tackling this worldwide issue. biotechnological approaches stand out as effective, eco-friendly, sustainable solutions managing toxic pollutants. However, complexity MNP presents challenges in its management regulation. Addressing requires cross-disciplinary research efforts develop implement more efficient, sustainable, scalable techniques mitigating pollution. This review explores various sources micro- resources, their impacts, strategies—including advanced approaches—and treating alleviate effects on health.
