This study aims to ascertain the effects of CO induced water acidification and leaks from Carbon Capture and Storage activities on the South American amphipod Hyale youngi. A 10-day acute toxicity test was performed using sediments from two sites located inside the Santos Estuarine System. They were subjected to five pH treatments (8.1, 7.6, 7.0, 6.5, and 6.0). Metals (Cd, Cu, Cr, Pb, Ni and Zn) and the metalloid As were analyzed to determine the influence of their acidification-related mobility on the amphipods mortality. The results showed that mortality becomes significant when compared to control in pH 6.5 in the Canal de Piaçaguera sediment (contaminated) and at pH 6.0 in Ilha das Palmas sediment (reference).
本研究旨在确定一氧化碳导致的水体酸化以及碳捕获与封存活动中的泄漏对南美双足类动物杨氏透明钩虾的影响。使用桑托斯河口系统内两个地点的沉积物进行了为期10天的急性毒性试验。它们接受了五种pH处理（8.1、7.6、7.0、6.5和6.0）。分析了金属（镉、铜、铬、铅、镍和锌）以及类金属砷，以确定其与酸化相关的迁移性对双足类动物死亡率的影响。结果表明，与对照组相比，皮阿萨瓜埃拉运河沉积物（受污染）在pH 6.5时以及帕尔马斯岛沉积物（参考）在pH 6.0时，死亡率显著升高。
