The Ecologic Institute, in cooperation with AquaEcology, developed an information poster addressing the environmental impacts of sunscreen products on marine ecosystems. The poster focuses on the release of sunscreen into the sea during swimming and bathing and highlights this pathway as a relevant but often underestimated source of chemical pressure. Estimates suggest that approximately 14,000 tonnes of sunscreen products enter marine environments each year, where certain ingredients may adversely affect marine organisms.

The poster presents scientifically documented effects of selected UV filter substances. These include the reduction of photosynthetic activity in algae caused by octinoxate, the accumulation of octocrylene in the tissues of marine mammals, and the genotoxic effects of oxybenzone on corals, which can contribute to coral bleaching. In addition, the poster lists other substances of potential environmental concern that are relevant for the assessment of chemical pressures in marine waters.

Alongside the description of environmental impacts, the poster provides practical recommendations for individual action to reduce pressure on the marine environment. These include the use of UV-protective clothing, avoiding exposure during midday sun, and making informed choices regarding sunscreen ingredients. As part of communication activities supporting the implementation of the EU Marine Strategy Framework Directive, the poster contributes to the targeted dissemination of scientific knowledge and to public awareness-raising on the protection of marine ecosystems.
