Microplastics in sandy beaches of Thermaikos Gulf: quantification and spatial distribution

This study looks into microplastic pollution along the coast of the Thermaic Gulf. Samples were collected from eight locations and analyzed for their amount, size, shape, and where they were found. The highest levels appeared in tourist-heavy areas, while fibers were more common in places with fishing activity. Most microplastics were found in the midlittoral zone, likely due to how water moves and deposits them. The results point to tourism as a major source of pollution and highlight the need for regular monitoring and better measures to protect the marine environment.
