Uptake rate constants of MeHg in six different algal species over short-term exposures. Values are normalized to the initial dissolved MeHg concentrations in the media and are expressed on per cell, per μm² cell surface area, and per μm³ cell volume bases for the first 4 h of exposure. Algal species on the x axis are arranged in increasing size order, with the cyanobacterium being the smallest cell and the dinoflagellate the largest cell.
