From Rivers to Oceans, the Hydrological Footprint of Microplastics: Policy Solutions and Life Cycle Assessment for Sustainable Development Goal's Alignment
AI summary Read the abstract
This review paper summarizes existing research on how microplastics move from production through disposal in rivers and oceans, examining their effects on aquatic animals and potential human exposure through food. It discusses how microplastic pollution may interfere with United Nations sustainable development goals and highlights life cycle assessment as a tool for studying this issue.
ABSTRACT The impact and dispersion of plastics and microplastics (MPs), or every stage of its lifecycle including manufacture, utilization, release, transportation, accumulation, and ultimate disposal, can be cumulatively termed as “microplastic footprint”. The principal objectives of this study are to investigate the lifecycle of MPs in aquatic environments; to evaluate their ecological effects on aquatic organisms, and to evaluate human health concerns through the food chain, hindering the path to achieving sustainable development goals (SDGs). Understanding these aspects is crucial for the development of effective mitigation measures including the reduction of MP production in each stage of its life cycle through proper Life Cycle Assessment (LCA) and possible sustainable ways and alternatives. The concerns of MPs are being investigated with a focus on how they might hamper the implementation of sustainable plans and strategies for achieving the United Nations SDGs.

Microplastics in Aquatic Ecosystems: A Critical Review of Sources, Transport Mechanisms and Ecotoxicological Risks
AI summary Read the abstract
This review provides a broad overview of microplastic pollution in rivers, oceans, and other aquatic environments, covering where these particles come from, how they move through water systems, and the harm they can cause. Evidence indicates that microplastics accumulate toxins and disrupt growth, feeding, and reproduction in aquatic species, with potential consequences for human health through seafood and drinking water. The authors stress the need for better global monitoring, stronger waste management systems, and development of eco-friendly plastic alternatives.
