摘要: Changes in the marine carbonate system may affect various calcifying organisms. This study is aimed to compare sensitivity of embryo-larval development two species sea urchins (Paracentrutos lividus and Lytechinus variegatus) collected exposed samples from different coastal zone (Spain Brazil) ocean acidification. The results showed that larval stages are very sensitive small changes seawater's pH. larvae P. be more acidified elutriate sediments than L. variegatus urchin. Furthermore, this has demonstrated CO2 enrichment aquatic ecosystems cause on mobility metals: Zn, Cu, Fe, Al As, which was presented behavior among them. Although an increase metals found, using principal component analysis pH reduction show highest correlations with toxicity main inhibition. In comparative it both able assess potential effects acidification related by near future scenarios risk associated leakages Carbon Capture Storage (CCS) process, importance studies zones improve understanding impacts caused
