Abstract
The vapours of trichloroethylene and/or 1,1,1-trichloroethane are trapped on silica gel contained in a robust sampling tube made from a galvanized iron pipe connector and Simplifix couplings. Air from the worker's breathing zone is sucked through the tube by a battery operated personal sampling pump, sampler and pump being held on a harness fitted to the worker. Adsorbed solvent is eluted with methanol and estimated by gas chroma-tography using Chromosorb 101 as stationary phase. Mean exposure over a shift can be determined and related to parallel physiological measurements.Keywords
