NIOSH 1991 Feb:609-613
An Army Corps of Engineers cleanup of mercury (7439976) contaminated soils was suspended due to the lack of a real time air monitoring method for dimethyl-mercury (593748) (DMM). Criteria were established for selecting a real time instrument for monitoring DMM which indicated that the instrument had to be portable and permit operation by nontechnical personnel, to have real time or semireal time monitoring capabilities, and that it had to be specific to organomercurials. The Arizona Instruments Model 411, Gold Film Mercury Vapor Analyzer was selected as the instrument of choice. This study indicated that gold film mercury vapor detectors have definite potential in monitoring for DMM. The authors conclude that Model 411 appears to be promising because of its simplicity, stability, and effectiveness as a screening tool. As with any screening device, it should not be relied upon exclusively. It should be incorporated into a multitiered sampling and monitoring program.
