Microplastics on Lake Champlain beaches

This study investigates microplastic pollution along the beaches of Lake Champlain. In 2024, sand samples were collected from twelve beaches (six in Vermont and six in New York) and sieved. Visible microplastics are being imaged under a microscope and categorized by size, shape, and color; selected particles have been analyzed using FTIR, revealing diverse polymer types. Density separation is pending. This research addresses spatial patterns, human activity influence, and ecological risk. In 2025, expanded sampling across 24+ beaches will assess vertical and horizontal variation, seasonal change, and visitation-level effects. Findings aim to inform freshwater pollution management in the Lake Champlain Basin.
