Like other plants, algae are recipients of, and respondents to, heavy metals (1-3). It has been suggested that the inhibition of photosynthesis and N2fixation by heavy metals is caused by depletion of ATP and reluctant pools by the heavy metal (4). Such cations also inhibit the cyanobacterial uptake of N03 -, NH4 +, and P043 (5-7). The rare occurrence of heavy metals as single species in any environment prompted us to investigate the interactions of Hg2 + with Nit ~, Cue +, Cd2 +, and CH3Hg+ in bimetallic combinations.
