What is Microplastic Release from Bottle Caps about?

This study examined microplastic (MP) release from reusable plastic water bottles with screw cap systems. The researchers analyzed bottles before and after opening and closing once or 11 times. They found 131 MP particles per liter after one opening and 242 MP particles per liter after 11 openings, primarily from the polypropylene caps. The majority of particles were small, between 10-50 micrometers. No MP was detected before opening, indicating the screw cap system is a source of MP abrasion during use.
