||Comparison between exhaled breath condensate analysis as a marker for cobalt and tungsten exposure and biomonitoring in workers of a hard metal alloy processing plant
||Apr. 2009, Vol.82, No.5, p.565-573. Illus. 75 ref.
||Cobalt (Co), tungsten (W) and tungsten carbides (WC) are major constituents of hard metal alloys. This study examined the feasibility of using exhaled breath condensate (EBC) as an alternative to urinary determinations for evaluating exposures to Co and W. A total of 62 subjects were recruited from a hard metal processing plant in Germany. Examinations included the airborne workplace concentrations, spirometry, and determinations of Co and W in EBC and urine. It is concluded that urinary concentrations of Co and W remain more reliable indicators of current workplace exposure than EBC concentrations. Other findings are discussed.
