Sink to River – River to Tap – A review of potential risks from nano-particles & microplastics

Hi all…following up from the WHO report on microplastics that I recently circulated, the UK Water Industry Research Limited has just released a report entitled “Sink to River - River to Tap - A review of potential risks from nano-particles & microplastics.”

Microplastics in drinking water-new WHO report

Hi all…the WHO has released a lengthy report entitled ‘Microplastics in Drinking Water’. It is a good compilation of potential issues associated with microplastics and is available for free download.
