Screen&Toxin

The Screen&Toxin project was designed to clarify the following main questions:

Can a concomitant exposure to okadaic acid (OA) and an active ingredient of sunscreen products (oxybenzone) increase the interdiction period of the capture and consumption of shellfish (Donax trunculus) by an “overload” of the metabolic pathways that ensure the elimination of this marine toxin?
Can natural substances (such as marine macroalgae ingredients) act as alternative UV filters and not interfere with the elimination of okadaic acid by D. trunculus?

Mission

Clarification on the interference of an active ingredient of sunscreens (oxybenzone) in the metabolism of the marine toxin okadaic acid by the clam Donax trunculus, while contributing with measures to mitigate the long interdiction periods of the species capture and to rise public awareness on the importance of using products with alternative UV-filters.

Vision

To play an active role in sustainable development by raising awareness to the importance of using oxybenzone-free sunscreen products and seeking "greener" alternatives to contribute for aquatic systems and resources preservation.

Future Impact

As a positive impact of the SCREEN&TOXIN project, an improvement in the quality of coastal water is expected by reducing the levels of oxybenzone, making it possible to reduce the time of interdiction of fishing and shellfish capture and an increase in the quality of the resource. These improvements will also positively impact local tourism, encouraging the cultivation of bivalves and algae under controlled conditions.
