Review of the Literature on the Topic of Acidic Deposition on Stone

It is extremely difficult to determine how much of the deterioration observed on stones is due to “acid rain” since its action is not limited to one mechanism. Rather, it results from the interaction of various mechanisms, many of which also occur in natural weathering. The aim of this survey is to present a summary of the most relevant publications in the field of acid precipitation on stone to help identify the relative importance of the various factors that contribute to the deterioration of this material. It should also contribute in pointing out those areas in which further study and research will prove more fruitful.
