Tracking microplastics at the source: a comparative study of fluorescent and FTIR microscopy at a drinking water intake in the Perak River, Malaysia
Researchers measured microplastic contamination at a drinking water intake point on the Perak River in Malaysia, finding 12 different polymer types with most particles smaller than 10 micrometers.
