25. Why Arsenic? Two Motivations: Lack of specific chelators optimized for As(III) coordination geometry Lack of supramolecular main-group chemistry Widespread sources Found in association with Cu, Pb, Au Ore mining and refining; semiconductors Pesticides, agents of war, pharmaceuticals, CCA-treated lumber, minerals Health Effects 1-5 mg/day weeks-months—peripheral neuropathy, anemia >400ppb 3-7 years—hyperpigmentation, hyperkeratosis, leading to lesions and cancer >10ppb 30-40 years—skin cancer Lane County

26. Arsenic in Drinking Water EPA imposed a new drinking water standard on Jan. 1, 2006, from 50 ppb to 10 ppb As . Most arsenic contamination of drinking water is natural, due to local geology and mining.

27. “ Nanocoated Materials” for Metal Removal TiO 2 granules (Metsorb ® ) are marketed for use in heavy metal adsorption. Addition of a bifunctional ligand layer to metal-coated TiO 2 exposes a fresh metal binding surface which increases the capacity of the material for toxic metal adsorption.
