Seas and oceans are polluted by a wide range of compounds stemming from human activities. Our team wants to heighten awareness about environmental pollution and particularly its devastating consequences on the aquatic life. In this line of thinking we are driven to design a bioremediation tool based on the considerable filtration capacity of sponges to decrease the marine pollution and protect aquatic ecosystems. We aim at tackling elements of the main pollutant families by focusing on 5 toxic agents: Polychlorinated Biphenyls (PCBs), nitrite, phenol, lead and cadmium.

The PCBs are synthetic organic compounds widely used by industries and found in large quantities in natural environments due to years of intensive use. They are carcinogenic at low-dose through a chronic exposure and particularly bioaccumalable all along the food chain. Likewise, lead and cadmium are bioaccumulable. They can contaminate fishes making them unfit for consumption, causing severe health damages to human who eat regularly these contaminated fishes. Phenol is not recognized as carcinogenic however its toxicity is real, particularly on cardiovascular system and kidneys. It can be found in the environment as a degradation product of pesticides, dyes and polymers. The degradation of fertilizers gives nitrite, another toxic compound for humans, aquatic flora and fauna.
