In the release 4.1 of the ConsExpo program the following alterations with respect to the version 4.0 have been have been made:

• The inhalation exposure model to sprays has been revised, based on experimental data
• Bug fix: in version 4.0 mass conservation was violated in certain applications of the ‘dermal diffusion’ model in combination with the ‘diffusion through skin’ uptake model. This fault has been remedied in version 4.1
• Bug fix: in version 4.0, the inhalation ‘Exposure to Vapour’ model: the option ‘limit air concentration to the vapour pressure of pure substance’ did not work as expected. The problem has been addressed in version 4.1
• Bug fix: in ConsExpo 4.0, when retrieving default exposure scenario’s from the database, previously set data for compound and product were erased. Problem has been corrected
• Minor changes to program interface: renaming of parameters and model options
