Summary

Researchers monitored microplastic abundance in the River Thames across seasons, finding that flow rates and rainfall patterns significantly influence particle concentrations and distribution in UK river systems. The study highlights a regulatory blind spot -- microplastics are not yet monitored as part of official UK water quality testing -- leaving the public without systematic data on their exposure through river environments.

Study Type Environmental

In the UK, microplastics are considered an emergent contaminant but not pollutants and, at this moment, are not monitored as part of water quality tests. As a result, microplastic abundance within many UK rivers is unknown. This also means that the many factors...
