1 DEPARTMENT OF GEOLOGY & ENVIRONMENTAL SCIENCES 280 Central Ave. Science Complex 340 Fredonia, NY 14063 SYNTHETIC POLYMER CONTAMINATION IN BOTTLED WATER Sherri A. Mason*, Victoria Welch, Joseph Neratko State University of New York at Fredonia, Department of Geology & Environmental Sciences *Corresponding author EXECUTIVE SUMMARY Tested 259 individual bottles from 27 different lots across 11 brands o Purchased from 19 locations in 9 countries 93% of bottled water showed some sign of microplastic contamination o After accounting for possible background (lab) contamination Average of microplastic particles >100 um per liter of bottled water o Confirmed by FTIR spectroscopic analysis o Twice as much as within previous study on tap water Including smaller particles ( 100 um), average of 325 microplastic particles per liter o Identified via Nile Red tagging alone o No spectroscopic confirmation o Range of 0 to over 10,000 microplastic particles per liter o 95% are particles between 100 um in size For particles > 100 um: o Fragments were the most common morphology (66%) followed by fibers o Polypropylene was the most common polymer (54%) Matches a common plastic used for the bottle cap o 4% of particles showed presence of industrial lubricants
