📋 Tender Overview
The Peruvian Sea Institute (IMARPE), through its decentralized headquarters in Ilo, carried out scientific monitoring on the Boca del Rio, Pozo de Lisas Norte and Pozo de Lisas Sur beaches, located in the province of Ilo (Moquegua), with the aim of evaluating the presence of plastic waste on the coast. The study allowed us to quantify and characterize mesoplastics (fragments between 5 and 25 millimeters) and macroplastics (greater than 25 millimeters), as well as to identify their possible sources of origin. This information will contribute to strengthening waste management and the protection of coastal ecosystems.
The evaluations, carried out during the summer season, showed that macroplastics are the most common waste on these beaches. The analyzes carried out in the laboratory mainly identified materials associated with everyday consumption, such as bottles, bags, lids and food containers, which reach the sea or remain on the coastal strip.
The results indicate that most of this waste would be linked to human activities in the area such as tourism, the main source of pollution, followed by fishing activity, especially fragments of disused gear. Previous investigations carried out by IMARPE had classified some sectors of these beaches as dirty according to international standards, which reinforces the importance of continuing monitoring during 2026.
With these investigations, IMARPE strengthens the generation of scientific knowledge on marine pollution and provides fundamental information for the conservation of coastal ecosystems, and contributes to promoting responsible waste management and the sustainable use of marine resources for the benefit of local communities and the health of the ocean.
