5. Lead Speciation in Microorganisms
Stewart, Theodora J.
The biogeochemical cycles of lead (Pb) have been largely affected by anthropogenic activities as a result of its high natural abundance and use over the centuries . At sites more strongly impacted by urbanization  and mining , Pb is found at high nano to low micromolar concentrations in surface waters, and can be significantly higher in soil and sediment . Microorganisms are found everywhere and their responses to Pb exposure can range from resistant to highly sensitive [5, 6]. These varying levels of toxicity can be attributed to the cellular handling of Pb, making it important to understand the role of intracellular Pb speciation for more accurate toxicity predictions.
