Abstract

Contaminants of emerging concern including pharmaceuticals, plasticizers, new pesticides, perfluorinated compounds, abuse substances or personal care products to cite a few, are increasingly detected in marine waters, sediments and organisms, potentially posing a serious threat to biodiversity due to their documented toxicity at very low concentrations: however, their presence, distribution and environmental risk assessment are not considered in any of routinary national monitoring plans. Normative regulations on the quality and protection of the marine environment are mostly based on the analysis of well-known and traditional pollutants, without the possibility to be updated to the synthesis of new chemicals which are produced and released into the environment at a rate of 1,500 novel compounds every year. The inadequacy of regulated chemicals contributes to hamper our capability in halting the impact of pollution which is listed as one of the top five causes of biodiversity loss. In addition, chemical analysis of individual compounds does not consider synergistic, additive or antagonistic effects occurring in organisms exposed to complex mixtures, their long-term consequences and further modulations by other stressors, such as changes in climate system (temperature, salinity and acidification). Hence the need to orient this Action toward a better understanding on the presence, impact and risks for biodiversity arising from emerging pollutants released from national sources to the Mediterranean, thus providing a scientifically sound basis for an integrated chemical and effect-based assessment of the threat. However, the lack of knowledge on the hazard caused by pollution to biodiversity is not only cause of concern: it also offers major challenges and opportunities for technological innovation, new business models and economic development to counteract this impact in line with recent EU Zero Pollution Action Plan and the Horizon Missions.
