Calculated surface recession of limestone in μm (one-year exposure), based on the dose-response function for the SO₂ dominating situation, for the Milan city centre, reported either as one single value based on the EMEP 50 km × 50 km grid cell (left, 4.4 μm) or as a map of the city centre based on local data (right, 6.8 to 11.6 μm). Coloured symbols (blue, red, and yellow) in the map to the right indicate different types of cultural heritage [59].
