Each test substance (0.9 - 30 mg) was dosed on a glass tray, placed on the chamber floor. Humidity was controlled by a humidifier and a dehumidifier and intermittent ventilation. Humidity-driven mobilisation of the non-volatile substances transferred the substances from the tray into chamber air, where it was detected with TVOC sensors. The water vapour was condensed in the dehumidifier, where the test substances could be detected using capillary electrophoresis analyser.
Humidification and dehumidification and ventilation removed the test substances from the trays. This protocol could be applied to contaminated indoor spaces during low activity hours to reduce human exposure the adverse substances.
