What drink has the most microplastics?

What drink has the most microplastics depends on packaging, processing, and water source, but studies suggest bottled water contains significantly more microplastics than tap water, and certain beverages in plastic bottles show higher counts. Research found that bottled water can contain hundreds of thousands of micro and nanoplastic particles per liter, especially when bottles are exposed to heat or reused, due to shedding from plastic bottle itself. Other drinks that show high microplastic levels include beer, as studies found microplastics in many beers, likely from water and processing, tea bags made from plastic that release billions of microplastics when steeped in hot water, and soft drinks and juices in plastic bottles. Among common drinks, bottled water is often cited as having most microplastics per serving, with some studies showing average of 240,000 particles per liter in bottled water versus far fewer in tap water. Plastic tea bags are also extremely high when brewed. Tap water generally has lower microplastic counts than bottled water. To reduce intake, use filtered tap water in glass or stainless steel, avoid plastic tea bags, and limit bottled drinks. Research is ongoing and counts vary by brand and method.
