Due to their interaction with the environment, particles are loaded with chemicals (e.g. in aerosols). The central aim of the biomedical aerosol research is the distribution, deposition and retention of inhaled aerosol particles in the lung and their effect on the lung functions as well as on the cardio-vascular system. For this purpose, the characterisation of the aerosol particles and the identification and quantification of chemical stressors located on the aerosol particles (chemical load) is an essential contribution to the impact research.
In order to meet the requirements necessary for these complex investigations, several different analytical techniques need to be involved. As one part of these techniques, thermoanalytical investigations coupled to gas analysis systems, supply valuable information, both, for the characterisation of environmental aerosols as well as for model aerosol particles.
The results of these thermoanalytical investigations are presented and discussed in connection with other investigations.
