Ocean acidification increases cadmium accumulation in marine bivalves: a potential threat to seafood safety Wei Shi1, Xinguo Zhao1, Yu  Han1, Zhumei Che2, Xueliang Chai3 & Guangxu Liu1 To date, the effects of ocean acidification on toxic metals accumulation and the underlying molecular mechanism remains unknown in marine bivalve species. In the present study, the effects of the realistic future ocean pCO2 levels on the cadmium (Cd) accumulation in the gills, mantle and adductor muscles of three bivalve species, Mytilus edulis, Tegillarca granosa, and Meretrix meretrix, were investigated. The results obtained suggested that all species tested accumulated significantly higher Cd (p   adductor muscles (Fig. 1).

Gene expressions of pgp-5 in different pCO2 levels.  After raising in CO2 acidified seawater (pH 7.4) for 30 days, pgp-5 expression was significantly lower than that of the control (p
