Comparison of sampling positions when measuring personal exposure to solder fume.
A sampling device based on a telephone headset was developed and used to support a sampler close to the mouth during personal exposure monitoring of solder fume. In a field trial, it was compared with the established method of mounting the sampler on the arm of a pair of spectacles, and a linear correlation was evident between the two positions (slope 1.56 +/- 0.05, r(2) = 0.98). Although the headset sampler held the sampler closer to the breathing zone, experience showed that the spectacles position was less intrusive on the subject and allowed a more consistent and stable sampling position. On balance, the spectacles position was the preferred sampling location.
