Application of the Paracentrotus lividus sea-urchin embryo-larval bioassay to the marine pollution biomonitoring program in the Tunisian coast

The utility of urchin fertilization and gastrulation rates and normal pluteus larval frequencies as useful bioassays to monitor the exposure of marine ecosystems to mixed pollution is recommended.

Impact on Fertility Rate and Embryo-Larval Development Due to the Association Acidification, Ocean Warming and Lead Contamination of a Sea Urchin Echinometra lucunter (Echinodermata: Echinoidea)

The present study suggests that pH decrease, temperature increase and metal pollution may have a significant impact on E. lucunter reproductive cycle and the development test was shown to be more sensitive than the fertilization test in all the studied scenarios.

Ocean acidification increases cadmium accumulation in marine bivalves: a potential threat to seafood safety

The results obtained suggested that all species tested accumulated significantly higher Cd in the CO2 acidified seawater during the 30 days experiment and the health risk of Cd via consumption of M. meretrix at pH 7.8 and 7.4 significantly increased 1.21 and 1.32 times respectively, suggesting a potential threat to seafood safety.

Metal contamination increases the sensitivity of larvae but not gametes to ocean acidification in the polychaete Pomatoceros lamarckii (Quatrefages)

The potential for polychaete larvae to be affected by predicted ocean acidification conditions and that chronic coastal pollutants, such as copper, have the potential to alter larval susceptibility to ocean acidisation conditions are demonstrated.

Interactive effects of metal pollution and ocean acidification on physiology of marine organisms

Analysis of the interactive effects of OA and trace metals on marine organisms with a focus on the physiological basis of these interactions shows that the responses to elevated CO2 and metals are strongly dependent on the species, developmental stage, metal biochemistry and the degree of environmental hypercapnia, and cannot be directly predicted from the CO2-induced changes in metal solubility and speciation.

Effects of increased pCO2 and temperature on trace element (Ag, Cd and Zn) bioaccumulation in the eggs of the common cuttlefish, Sepia officinalis

The results suggest that pH and temperature affected both the permeability properties of the eggshell and embryonic metabolism, and the need to further evaluate the likely ecotoxicological impact of the global change on the early-life stages of the cuttlefish.

Ocean acidification increases copper toxicity to the early life history stages of the polychaete Arenicola marina in artificial seawater.

Findings add to the growing body of evidence that OA will act to increase the toxicity of copper to marine organisms, which has clear implications for coastal benthic ecosystems suffering chronic metal pollution as pCO2 levels rise and drive a reduction in seawater pH.

Studying the effect of CO2-induced acidification on sediment toxicity using acute amphipod toxicity test.

The data obtained revealed that CO2-related acidification would lead to lethal effects on amphipods as well as the mobility of metals, which could increase sediment toxicity.
