Researchers from DRI and UNR are studying microplastic pollution in Lake Tahoe, which ranks third globally in microplastic concentration. Key findings include: Microplastics range from 5 mm to 1 micron, with particles under 20 microns posing health risks.
Current levels in drinking water are too low to cause concern, but chemical carriers are worrying. South Lake Tahoe's single-use water bottle ban shows positive results.
Prevention through reducing plastic use is emphasized as the best solution.
