Summary
This comprehensive narrative review synthesises peer-reviewed evidence on the ubiquity of micro- and nanoplastics (MNPs) across terrestrial, aquatic, and atmospheric environments, their primary sources of origin, and their toxicological implications for human and ecosystem health. The paper likely addresses ingestion, inhalation, and dermal exposure routes, alongside evidence of MNP accumulation in human tissues. It also critically reviews the adequacy of current international and regional regulatory responses to plastic pollution, identifying gaps between scientific understanding and legislative action.
UK applicability
The findings are broadly applicable to UK conditions, where microplastic contamination of soils, waterways, and food products is an established concern; the review's regulatory analysis is particularly pertinent given ongoing UK post-Brexit environmental policy development and engagement with international plastic treaty negotiations.
Key measures
Plastic particle size classifications; environmental concentration data; exposure pathways; toxicological endpoints; regulatory thresholds and legislative frameworks
Outcomes reported
The review examines the current state of research on micro- and nanoplastic contamination across environmental compartments, assesses documented and potential human health risks, and evaluates existing regulatory frameworks governing plastic pollution.
