Only 4 of 50 microplastic studies in drinking water meet full quality standards

A peer-reviewed assessment of 50 studies on microplastics in drinking water and freshwater sources found major quality gaps in sampling and analysis methods. The study reports that microplastics are frequently detected across all water types tested, but methodological inconsistencies make it difficult to compare results across studies.

only four out of 50 studies received positive scores for all proposed quality criteria, implying there is a significant need to improve quality assurance of microplastic sampling and analysis in water samples.
