@purascans: 🔍 Sourced From Public US & EU Data 🔍 A plastic toothbrush sheds microplastics every time it's used — studies estimate up to 120 particles per brushing, around 90,000 a year. The bristles are nylon, a hard plastic, and the friction grinds microscopic fragments off them — and the cheaper the brush, the more it sheds. A brush with natural boar or plant-based bristles doesn't shed plastic. Scanned with the Pura app.
