Synthetic particles as contaminants in German beers

A total of 24 German beer brands was analysed for the contents of microplastic fibres, fragments and granular material. In all cases contamination was found. Counts ranged from 2 to 79 fibres L-1, from 12 to 109 fragments L-1 and from 2 to 66 granules L-1. The results show a high variability between individual samples and samples from different production dates. Possible sources of this contamination with foreign materials are discussed.
