Analytical methodologies for chromium speciation in solid matrices : a survey of literature

The analytical literature about chromium speciation in solid samples has been surveyed. From 451 articles published on the speciation of chromium from 1983 to 1997, the methodologies to do speciation in solids after sample pretreatment are discussed, through consideration of the types of samples and their dissolution, the analytical techniques employed for chromium measurement, and the figures of merit of the 86 papers reported in the Analytical Abstracts data base. References about chromium speciation in industrial samples report the analysis of aerosols, airborn particulates, alloys, aluminum, ashes, building materials, catalysts, cement, coal, dust, dyes, fibers, industrial wastes, iron, leather, metals, pharmaceutical products, steel, timbers, welding dust and welding fumes.
