Summary
This paper examines potential methodological artefacts in toxicity testing of nanoplastics and microplastics (NMPs) across mammalian and ecotoxicological systems. The authors propose a framework of control experiments applicable to pelagic, sediment, and soil organism studies, with the aim of reducing false positive and false negative results. The work contributes to standardisation of NMP hazard assessment methodology.
Regional applicability
The recommendations are directly applicable to UK regulatory toxicology and environmental monitoring programmes, including soil and water quality assessments under Environmental Quality Standards and the Environmental Permitting Regulations. Standardised control protocols would support UK environmental agencies in consistent risk characterisation of microplastic and nanoplastic contamination.
Key measures
Taxonomic assessment of control experiment protocols; evaluation of artefact sources in toxicity tests; false positive and false negative rates in nano- and microplastic ecotoxicity studies
Outcomes reported
The study identifies potential artefacts and recommends control experiments for toxicity testing of nanoplastics and microplastics across mammalian, pelagic, sediment, and soil organism studies. It evaluates false positive and false negative results in ecotoxicity assessments.
