Metal accumulation and partitioning in two Antarctic marine microalgae from exposure to cadmium, copper, nickel, lead, and zinc

This data describes the cellular metal concentrations of Phaeocystis antarctica and Cryothecomonas armigera following exposure to metals singly and in mixtures in laboratory studies. Microalgae were cultured in 80 mL of filtered (less than 0.45 um) seawater and low concentrations of nutrients supplemented with metal stocks to give a range of single and mixture exposures to the metals cadmium, copper, nickel, lead, and zinc. The cellular accumulation and partitioning are used to explain the metal's toxicity (cellular metal fractions are compared to the toxicity data provided in 10.4225/15/5ae93ff723ff8) and assess the risk bioaccumulation of metals to Antarctic marine microalgae may pose in the Southern Ocean food web.
