A.3.1.4 Data fine-tuning and studies delivery

This document details the scientific monitoring activities of the project, which primarily concentrated on analyzing macrolitter and microlitter in key environmental compartments. These compartments include beaches, the sea surface, and the ingestion of litter by mussels, commercially valuable fish species, and sea turtles. The investigations were conducted in five distinct pilot study areas, aiming to comprehensively assess the presence and impact of litter across different levels within the marine ecosystem. The document outlines the methodologies and findings of these studies, providing essential data for understanding and mitigating marine litter pollution.
