Hexavalent chromium in welding fume

Evaluates the current Australian Standard method (AS3853.1) for the determination of total hexavalent chromium (Cr(VI)) in stainless steel welding fume. Investigates the extraction kinetics of this Cr(VI) into a range of media. Develops an analytical method for the determination of Cr(VI) in acidic extract solutions and investigates the extraction of Cr(VI) under simulated in vivo conditions.
