We assess and quantify threats to ecosystem health that are associated with toxic metal(loid)s. We determine how microbes interact with contaminants at the cellular level and evaluate the consequences of these interactions at the ecosystem level. We investigate how microbes sense and transform metals, particularly for detoxification, how such processes evolved, and how this information can be applied to the development of novel analytical and bioremediation tools.
