DustEx is a model to assess exposure to semi-volatile substances from consumer products that are introduced into the indoor environment.
The typical products considered are solid material products (e.g. flooring, wall covering, electronic devices). SVOCs are released from these products into indoor air. Depending on their physicochemical properties, these substances may subsequently adsorb to
Adults and children in the room are exposed to SVOCs by:
For SVOCs released indoors it may not be clear beforehand which of these pathway(s) will be relevant. The DustEx model calculates the daily average exposure to the substance via each of these four pathways. For this reason DustEx enables a more complete assessment of exposure, reducing the probability of overlooking crucial pathways in the exposure assessment.
DustEx calculates the daily average exposure of the substance via each of the pathways separately as well as the total, aggregate, exposure via all pathways combined. In addition to deterministic calculations, the DustEx tool also supports probabilistic evaluations.
The model was developed by the National Institute for Public Health and the Environment and ETH Zürich in the CEFIC LRI project B12. It has been evaluated by comparing the results to those of field experiments (Sukiene et al. Environ. Sci. Technol. 2016 : 50 (8), pp 4296–4303) performed by ETH Zürich.
