This column highlights available standardized methods that are applicable to surface samples for subsequent metals measurement, notably beryllium. Within the arena of beryllium surface sampling, our goal is to encourage the development of voluntary consensus standards in areas of interest for which such standards are presently unavailable. Methods for beryllium sampling from smooth, hard surfaces are now reasonably well standardized, as evidenced by the availability of relevant ASTM International standards. Additionally, vacuum sampling methods for collecting dust from rough, porous (and other) surfaces have also been standardized in the form of ASTM International procedures. Bulk sampling methods are also well standardized, and the use of voluntary consensus standards is encouraged. However, dermal sampling methods for metals such as beryllium require better harmonization and evaluation. Efforts are currently under way to fill these gaps.
