A robust bioassay to assess the toxicity of metals to the Antarctic marine microalga Phaeocystis antarctica
Abstract Despite evidence of contamination in Antarctic coastal marine environments, no water‐quality guidelines have been established for the region because of a paucity of biological effects data for local Antarctic species. Currently, there is limited information on the sensitivity of Antarctic m...
