We present an ecofriendly hydroxyapatite (HAP) material functionalized with tin (Sn/HAP) for efficient interfacial reduction of Cr(VI) to Cr(III). Tin was deposited on HAP at different concentrations (from 0.2 1.2 mmol/g) using colloidal or clear acid solutions SnCl2. The morphological and structural properties fresh used Sn/HAP samples were determined (N2 adsorption-desorption, transmission el...

Dozens of epidemiologic studies have been conducted since the late 1940s in an attempt to elucidate the relationship between exposure to chromium compounds and increased rates of certain cancers observed in several industries. The relationship between employment in industries producing chromium compounds from chromite ore and lung cancer has been well established in numerous studies. The relati...
