Abstract: | Nostoc calcicola cells exposed to mercuric chloride (0.05–0.25 M), methyl mercuric chloride (0.05–0.15 M) and the fungicide ceresan (phenyl mercuric acetate; 0.05–0.20 M) showed sensitivity in the sequence: methyl mercury3) over phenyl mercuric acetate (0.51×103); inorganic mercury occupied the intermediate position with a bioconcentration factor of 1.32×103. The data infer that larger molecules of organomercurials may not be taken up by cells at the rate and extent comparable to the smaller species. |
