“…In conclusion, our results show effects of Costa Concordia event both on epiphytic assemblages and biotic features of P. oceanica canopy, suggesting however a reduced influence of the chemical pollution, as also confirmed by results of studies carried out on biomarkers Mytilus galloprovincialis in the same study area (Regoli et al, 2014). According to these results, serious contamination events or consistent increase of environmental pollution should be excluded as only some episodic spills with reversible effects emerged (Regoli et al, 2014).…”

“…According to these results, serious contamination events or consistent increase of environmental pollution should be excluded as only some episodic spills with reversible effects emerged (Regoli et al, 2014). Moreover, structure of the canopy and its epiphytic assemblages could have been affected by synergic effects among factors associated with the body of the wreck and those related to the removal yard, where the first could have acted as a physical barrier to the natural hydrodynamics of the area, changing significantly the submerged landscape of the Disturbed site.…”

“…In fact, community level responses and ecotoxicological approaches are complementary, and the use of combined approaches of different disciplines is fundamental to achieve a good evaluation of an ecosystem health status (Martinez-Haro et al 2015). It would be important to integrate all the chemical and biological data within a quantitative weight of evidence (WOE) approach (Regoli et al 2014). In fact, a multidisciplinary approach is fundamental in chronically polluted sites as Mar Piccolo where the low sedimentassociated toxic effect identified in this study may be altered by changes in sediment physicochemical characteristics (redox potential, pH, water stratification, dissolved oxygen) or by anthropic alterations as dredging activities that can remobilize contaminants affecting their mobility and bioavailability (Bocchetti et al 2008).…”

The Mar Piccolo of Taranto (Ionian Sea, Southern Italy) is a semi-enclosed and strongly polluted basin. For decades, it has been subjected to different anthropogenic impacts. These stressors caused severe sediments contamination with high concentration of different pollutants (PAHs, PCB, heavy metals). In order to assess the current status of sediments contamination, an ecotoxicological investigation combined with chemical analysis (heavy metals, PAH, and PCB) has been performed. In order to derive ecologically relevant conclusions, a multiorganisms and multiend-points approach has been applied, exposing organisms from different trophic levels to elutriate and whole sediment. The battery of bioassays consists of a microalgal growth inhibition test (Dunaliella tertiolecta), acute and sublethal assays (end-points: mortality, immobilization and swimming speed alteration) on crustaceans larvae and juveniles, and rotifers (Amphibalanus amphitrite, Artemia salina, Corophium insidiosum and Brachionus plicatilis), and embryotoxicity test on echinoderms (Paracentrotus lividus). Considering the high levels of sediment contamination highlighted from chemical analysis, an unexpected very low toxic effect was observed, even considering the sublethal end-point (larval swimming speed alteration). The results of this study suggest a very complex contaminants dynamic in the Mar Piccolo sediments that, despite a strong level of contamination, seems to not affect in a proportional manner the biological compartment.

“…Using this approach, multiple Lines Of Evidence (LOE), including a characterization of the mineral resource (chemical composition, grain size), the accumulation of metals within organism tissues, the organism tissue biomarker response, and additional bioassays (MICROTOX, or similar), it is possible to quantify the risk associated with mining (Piva et al, 2011;Benedetti et al, 2012Benedetti et al, , 2014Regoli et al, 2014;Bebianno et al, 2015;Mestre et al, 2017).…”

Identifying Toxic Impacts of Metals Potentially Released during Deep-Sea Mining—A Synthesis of the Challenges to Quantifying Risk

et al. 2017

In January 2017, the International Seabed Authority released a discussion paper on the development of Environmental Regulations for deep-sea mining (DSM) within the Area Beyond National Jurisdiction (the "Area"). With the release of this paper, the prospect for commercial mining in the Area within the next decade has become very real. Moreover, within nations' Exclusive Economic Zones, the exploitation of deep-sea mineral ore resources could take place on very much shorter time scales and, indeed, may have already started. However, potentially toxic metal mixtures may be released at sea during different stages of the mining process and in different physical phases (dissolved or particulate). As toxicants, metals can disrupt organism physiology and performance, and therefore may impact whole populations, leading to ecosystem scale effects. A challenge to the prediction of toxicity is that deep-sea ore deposits include complex mixtures of minerals, including potentially toxic metals such as copper, cadmium, zinc, and lead, as well as rare earth elements. Whereas the individual toxicity of some of these dissolved metals has been established in laboratory studies, the complex and variable mineral composition of seabed resources makes the a priori prediction of the toxic risk of DSM extremely challenging. Furthermore, although extensive data quantify the toxicity of metals in solution in shallow-water organisms, these may not be representative of the toxicity in deep-sea organisms, which may differ biochemically and physiologically and which will experience those toxicants under conditions of low temperature, high hydrostatic pressure, and potentially altered pH. In this synthesis, we present a summation of recent advances in our understanding of the potential toxic impacts of metal exposure to deep-sea meio-to megafauna at low temperature and high pressure, and consider the limitation of deriving lethal limits based on the paradigm Hauton et al.Identifying Toxic Impacts of Deep-Sea Mining of exposure to single metals in solution. We consider the potential for long-term and farfield impacts to key benthic invertebrates, including the very real prospect of sub-lethal impacts and behavioral perturbation of exposed species. In conclusion, we advocate the adoption of an existing practical framework for characterizing bulk resource toxicity in advance of exploitation.
