“…Palma et al, 2008;Palma et al, 2009). Furthermore, P. varians' close taxonomic relationship to the Atlantic hydrothermal vent shrimp species Rimicaris exoculata, Chorocaris chacei and Mirocaris fortunata (Tokuda et al, 2006) makes this species an excellent case for comparison with these deep-living shrimps, and it has previously been used as such (Gonzalez-Rey et al, 2007;Gonzalez-Rey et al, 2008).…”

2002). The potential for depth range extension and colonisation of the deep sea may, therefore, be genuine for some shallow-water species. There is evidence that the echinoid Echinus acutus has extended its bathymetric range, indicating that migrations to the deep sea are still occurring (Tyler and Young, 1998 Accepted 8 December 2010 SUMMARY To date, no published study has assessed the full physiological scope of a marine invertebrate species with respect to both temperature and hydrostatic pressure. In this study, adult specimens of the shallow-water shrimp species Palaemonetes varians were subjected to a temperature/pressure regime from 5 to 30°C and from 0.1 to 30MPa. The rate of oxygen consumption and behaviour in response to varying temperature/pressure combinations were assessed. Rates of oxygen consumption were primarily affected by temperature. Low rates of oxygen consumption were observed at 5 and 10°C across all pressures and were not statistically distinct (P0.639). From 10 to 30°C, the rate of oxygen consumption increased with temperature; this increase was statistically significant (P<0.001). Palaemonetes varians showed an increasing sensitivity to pressure with decreasing temperature; however, shrimp were capable of tolerating hydrostatic pressures found outside their normal bathymetric distribution at all temperatures. 'Loss of equilibrium' (LOE) in ≥50% of individuals was observed at 11MPa at 5°C, 15MPa at 10°C, 20MPa at 20°C and 21MPa at 30°C. From 5 to 20°C, mean levels of LOE decreased with temperature; this was significant (P<0.001). Low mean levels of LOE were observed at 20 and 30°C and were not distinct (P0.985). The physiological capability of P. varians to tolerate a wide range of temperatures and significant hydrostatic pressure is discussed.

“…Moreover data indicate that the determination of any "temperature correction factor" will be different at high hydrostatic pressure for each metal in question and would have to be empirically determined for each case, and potentially for each biological species (see also: Kiffney and Clements, 1996;Gonzalez-Rey et al, 2007;Wang et al, 2014;for example).…”

“…Redox-inactive metals can be bound to glutathione to form non-toxic metal complexes. Reactive species are variously detoxified by enzymes including: superoxide dismutase (SOD), catalase (CAT), and peroxidases (PEROXs) (e.g., Company et al, 2004Company et al, , 2006aCompany et al, ,b, 2007Company et al, , 2008Bebianno et al, 2005;Gonzalez-Rey et al, 2008). Recently, Auguste et al (2016), Martins et al (2017) and Mestre et al (2017) have assessed the potential sub-lethal impacts of exposure to dissolved metals specifically in a range of deep sea species, including molluscs and echinoderms that do not inhabit metal-rich environments, and molluscs and crustaceans from hydrothermal-vent habitats; habitats that are naturally metal rich.…”

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

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.

“…Several studies have employed a comparative approach in hydrothermal vent and coastal shrimp, focusing on measuring in situ metal accumulation and/or biomarker expression (lipid peroxidation, antioxidant enzymes, metallothioneins) to explore adaptation to the toxic challenges presented by hydrothermal vent environment 20,37,38,83 . Although such an approach explores in situ physiology at ambient toxicant concentrations, it contributes relatively limited information about differences and/or similarities in sensitivity and responses to elevated toxicant concentrations among species.…”

Mineral prospecting in the deep sea is increasing, promoting concern regarding potential ecotoxicological impacts on deep-sea fauna. Technological difficulties in assessing toxicity in deep-sea species has promoted interest in developing shallow-water ecotoxicological proxy species. However, it is unclear how the low temperature and high hydrostatic pressure prevalent in the deep sea affect toxicity, and whether adaptation to deep-sea environmental conditions moderates any effects of these factors. To address these uncertainties we assessed the effects of temperature and hydrostatic pressure on lethal and sublethal (respiration rate, antioxidant enzyme activity) toxicity in acute (96 h) copper and cadmium exposures, using the shallow-water ecophysiological model organism Palaemon varians. Low temperature reduced toxicity in both metals, but reduced cadmium toxicity significantly more. In contrast, elevated hydrostatic pressure increased copper toxicity, but did not affect cadmium toxicity. The synergistic interaction between copper and cadmium was not affected by low temperature, but high hydrostatic pressure significantly enhanced the synergism. Differential environmental effects on toxicity suggest different mechanisms of action for copper and cadmium, and highlight that mechanistic understanding of toxicity is fundamental to predicting environmental effects on toxicity. Although results infer that sensitivity to toxicants differs across biogeographic ranges, shallow-water species may be suitable ecotoxicological proxies for deep-sea species, dependent on adaptation to habitats with similar environmental variability.
