Summary
This narrative review synthesises research on micro- and nano-plastics as emerging environmental contaminants of global concern. The paper examines sources, pathways, and environmental distribution of plastic particles, with implications for soil and water systems relevant to agriculture. As a 2020 review, it documents the state of knowledge on this emerging threat to agricultural productivity and food system resilience, though specific quantitative findings or mechanistic details are not determinable from the title alone.
UK applicability
Given the ubiquity of plastic pollution across global supply chains and atmospheric transport, findings on micro- and nano-plastic contamination pathways are likely relevant to UK soils, water, and agricultural systems. UK policy on agricultural contamination and food safety would benefit from understanding the scope and magnitude of this threat locally.
Key measures
Literature synthesis on micro- and nano-plastic occurrence, characterisation, environmental distribution, and hazard assessment across ecosystems
Outcomes reported
The study reviewed current research trends on the sources, distribution, environmental fate, and ecological impacts of micro- and nano-plastics globally. It synthesised evidence on contamination pathways and potential risks to agricultural systems and food security.
