“…However, toxicity for other sea urchin species shows significant variation, with EC 50 values as high as 341 μg L –1 also being recorded (Table ). Sensitivity does not appear to correspond to obvious phyletic groupings, with other Diadema species shown to be significantly less sensitive than D. antillarum . , Although embryo Ni burden increased with Ni exposure concentration (Figure B), this metric was not significantly correlated with toxicity (see below). A hyperbolic curve fit of the relationship between embryo Ni concentration and toxicity yielded a 96 h LA 50 (accumulation leading to 50% mortality) of 1.5 ± 0.5 pg embryo –1 (data not shown).…”

A 96 h toxicity test showed that the embryos of the New Zealand sea urchin (Evechinus chloroticus) are the most sensitive of all studied marine species to waterborne nickel (Ni), with the EC50 for the development of fully formed pluteus larvae found to be 14 μg L(-1). Failure to develop a standard larval shape suggested skeletal impairment. Whole body ions (Na, Mg) increased with Ni exposure and calcium influx was depressed. The effects of natural organic matter (NOM) on Ni accumulation and toxicity were also examined in three different seawater sources (nearshore, offshore, and near the outlet of a "brown water" stream). At low dissolved organic carbon (DOC) concentrations the brown water NOM was protective against Ni toxicity, however at higher DOC concentrations it exacerbated developmental toxicity in the presence of Ni. These results show that sea urchin development is highly sensitive to Ni via a mechanism that involves ionoregulatory disturbance, and that Ni toxicity is influenced by environmental factors such as NOM. These data will be critical for the development of water quality guidelines for Ni in the marine environment.

“…The chronic 28-d reproduction of A. pulchella was inhibited by 10% (IC10) at 65 µg Ni L -1 (Howe et al 2014 c; Table 6). The next most sensitive species was the sea urchin Diadema savignyi, in which fertilisation and development after 48-h exposure was inhibited by 50% (IC50) between 72-120 µg Ni L -1 (Rosen et al 2015; Table 5). The copepod Acartia pacifica, showed similar sensitivity to nickel, with a LOEC for 10-d egg production of 100 µg Ni L -1 (Mohammed et al 2010; Table 3).…”

“…Anemones and sea urchins were the most sensitive species to nickel, with toxic effects observed between 65 and 120 µg Ni L -1 (Howe et al 2014 a, b, c; Table 6, Rosen et al 2015; Table 5). Anemones are important species found on coral reefs of SEAM and are widely distributed throughout tropical and subtropical ecosystems (Howe et al 2012).…”

. (2016). A review of nickel toxicity to marine and estuarine tropical biota with particular reference to the South East Asian and Melanesian region. Environmental Pollution, 218 1308Pollution, 218 -1323 A review of nickel toxicity to marine and estuarine tropical biota with particular reference to the South East Asian and Melanesian region AbstractThe South East Asian Melanesian (SEAM) region contains the world's largest deposits of nickel lateritic ores. Environmental impacts may occur if mining operations are not adequately managed. Effects data for tropical ecosystems are required to assess risks of contaminant exposure and to derive water quality guidelines (WQG) to manage these risks. Currently, risk assessment tools and WQGs for the tropics are limited due to the sparse research on how contaminants impact tropical biota. As part of a larger project to develop appropriate risk assessment tools to ensure sustainable nickel production in SEAM, nickel effects data were required. The aim of this review was to compile data on the effects of nickel on tropical marine, estuarine, pelagic and benthic species, with a particular focus on SEAM. There were limited high quality chronic nickel toxicity data for tropical marine species, and even fewer for those relevant to SEAM. Of the data available, the most sensitive SEAM species to nickel were a sea urchin, copepod and anemone. There is a significant lack of high quality chronic data for several ecologically important taxonomic groups including cnidarians, molluscs, crustaceans, echinoderms, macroalgae and fish. No high quality chronic nickel toxicity data were available for estuarine waters or marine and estuarine sediments. The very sparse toxicity data for tropical species limits our ability to conduct robust ecological risk assessment and may require additional data generation or readacross from similar species in other databases (e.g. temperate) to fill data gaps. Recommendations on testing priorities to fill these data gaps are presented.

“…Endpoints included mortality, development/metamorphosis, and intrinsic rate of population increase (Gissi et al 2018; Wang et al 2020). Only one species of tropical sea urchin has been reported in the literature, with a NOEC for normal larval development of 23 µg Ni/L (Rosen et al 2015). Gastropods (snails) were also relatively sensitive to Ni, with EC10 values for growth rate inhibition at concentrations of 33 to 64 µg Ni/L (Gissi et al 2018; Wang et al 2020).…”

The absence of chronic toxicity data for tropical marine waters has limited our ability to derive appropriate water quality guideline values for metals in tropical regions. To aid environmental management, temperate data are usually extrapolated to other climatic (e.g., tropical) regions. However, differences in climate, water chemistry, and endemic biota between temperate and tropical systems make such extrapolations uncertain. Chronic nickel (Ni) toxicity data were compiled for temperate (24 species) and tropical (16 species) marine biota and their sensitivities to Ni compared. Concentrations to cause a 10% effect for temperate biota ranged from 2.9 to 20 300 µg Ni/L, with sea urchin larval development being the most sensitive endpoint. Values for tropical data ranged from 5.5 to 3700 µg Ni/L, with copepod early-life stage development being the most sensitive test. There was little difference in temperate and tropical marine sensitivities to Ni, with 5% hazardous concentrations (95% confidence interval) of 4.4 (1.8-17), 9.6 (1.7-26), and 5.8 (2.8-15) µg Ni/L for temperate, tropical, and combined temperate and tropical species, respectively. To ensure greater taxonomic coverage and based on guidance provided in Australia and New Zealand, it is recommended that the combined data set be used as the basis to generate a jurisdiction-specific water quality guideline of 6 µg Ni/L for 95% species protection applicable to both temperate and tropical marine environments.
