In this project, an analytical technology for end-exhaled air to conduct routine human biomonitoring (having been developed in the preceding project F 2169) will be evaluated using the example of workers exposed to tetrachlorethene. The methodology consists of sampling alveolar air using tubes without valves and an automated laboratory analysis process by gas chromatography.
Testing of the methodology will be performed with workers in different areas of tetrachlorethene use. As a comparison group, workers with no occupational exposure to tetrachlorethene will be involved.
