This study sought to find how much microplastic and what size of microplastic particles could be found both in raw groundwater and in drinking water from a groundwater source that had been purified.


Microplastic particles have been detected in various natural habitats and the digestive tracts of several species. These particles have also been reported in commercially available seafood, salt or bottled water starting discussions on potential implications for human health. To be able to assess the related risks, exposure concentrations and pathways need to be known. Here, we analysed ground water and drinking water for the presence of microplastics (>20 μm) using FTIR imaging.
