This project aims to contribute to the understanding of-black crusts growth in multi-pollutant influenced atmosphere, by focus on the key role of carbon particles as a vector of pollutant transport, deposition and transformation when embedded in patinas. Our comprehensive study will include measurements of soot particles in aerosols and in patinas including the two different fractions organic and elemental carbon. A new methodology for carbon analysis in patinas will be developed and a careful selection of target sites will allow us to constrain the role of the different combustion sources. Also, aesthetic damage to monuments will be related to the soot content of the crust. We will provide a formal and a user-friendly version of the modelling of particle transfer to be utilised for soiling estimates under present conditions and for future scenarios. The ultimate goal is to propose soot-based atmospheric thresholds.
