Researchers found microplastics smaller than 20 microns in bottled and tap water, urging the EU to revise detection limits. A study tested various water sources in Toulouse, revealing that 98% of microplastics were under 20 μm, posing potential health risks. The study's methodology was praised for its accuracy. The findings suggest bottled and tap water have similar microplastic concentrations, with groundwater being less contaminated. The implications for human health remain uncertain, highlighting a pervasive contamination issue.
