TL;DRAbstract

Standardized and quality assured sampling and analysis procedures for welding fumes are essential in efforts to demonstrate causality between occupational exposures and possible health effects. Three important but frequently overlooked sources of significant errors are: Loss of reactive species during collection and storage. Losses due to incomplete digestion of refractory matricies. Changes in species (solubility, oxidation state) during analysis. This ample evidence that monitoring and analysis dependent effects can lead to severe underreporting of exposures to toxic species such as Cr(VI) suggest the need for establishing standardized and appropriate protocols for use with welding fumes.
