MOESM1 of Trachyte weathering in the urban built environment related to air quality

Additional file 1. Trace-element chemical composition expressed as ppm of representative samples of Euganean trachyte from the Renaissance city walls of Padua determined by LA-ICPMS, on both surface (i.e., weathering crust or patina) and host rock (inner part). The samples are divided by different types of alteration and sampling location as in Fig. 2 (SCR, Bastione Santa Croce; GAR, Torrione dell’Arena; CSN, Bastione Castelnuovo; FST, Torrione Venier).
