Predicting metal effects and interactions on light output in bacteria (Photobacterium phosphoreum) using coordination chemistry data
- Univ. of Georgia, Aiken, SC (United States). Savannah River Ecology Lab.
Previous studies have shown correlations between Log of the negative solubility product for the metal hydroxide (Log -KsoMOH) and bioaccumulation of metals. The concentration of metal at which light output was reduced 50% (EC-50) in a marine bacteria (Photobacterium phosphoreum) was determined for several metals using Microtox{reg_sign}. Median affect concentrations were corrected for the amount of free ion using MINTEQ and graphed against Log -KsoMOH. A negative relationship was found between 15 minute EC50`s for all metals tested and Log -KsoMOH. The interaction between metal pairs were then determined to see if the interaction between metals could be predicted from Log -KsoMOH. In general, metals with similar values of Log KsoMOH interacted more strongly than metals with very different values. The authors conclude that metal effects (EC-50) could be predicted based on the Log -KsoMOH and that for metals with similar mechanisms of toxicity, the interaction between metals was also predictable based on Log -KsoMOH.
