In this Master’s thesis, how the effect of possible atmospheric processes can be considered in assessments of the environmental and health risks of ENPs is studied. A Gaussian atmospheric dispersion model is proposed to model the behavior and fate of ENPs after their release into the atmosphere. The model is developed to compute exposure estimates to be used in risk assessment. Additionally, a SimpleBox4Nano- model, found during the literature review, is recommended as an exemplary model that takes into account some of the atmospheric processes. The thesis focuses also on how the uncertainty that is present in the current models can be reduced through sensitivity analysis. A sensitivity testing was performed for the dispersion model considered in this thesis and it was found that exposure estimates change the most when model input parameters such as particle mass, particle size, atmospheric stability class, wind speed and size of the particle plume are varied. This kind of sensitivity testing could be a way to increase accuracy and reliability of the current risk assessment models.
