Abstract The toxicity and possible accumulation of ruthenium nitrosyl complexes by marine bacteria and test organisms have been studied, A range of these complexes show no toxic effects towardsEscherichia coli K12 at concentrations of mM and below. Yeasts are more sensitive, showing effects on growth at 10 ΜM. The ruthenium nitrosyl complexes tested are unable to permeate the cytoplasmic membrane ofE. coli. This may account for their lack of toxicity. However, these compounds did not have significant inhibitory effects on Mg2+-ATPase activity in cell-extracts, I50 values lying in the range 2 to 125 Μmol(mg protein)−1. Marine bacteria are capable of taking up ruthenium complexes from simulated effluent, but this cannot be demonstrated in the presence of sediment which competes effectively for binding of complexes. There is minimal likelihood of concentration of ruthenium compounds from effluents by marine bacteria.
