Talk:Origin of Salts

This is a suggestion for changes to the abstract. I have not heard of fortification or natural alteration circle in this context. Also it may be an idea to replace anthropogenic intervention with a more common term.

Abstract Salts that cause damage to wall paintings and cultural heritage made of stone, brick and other building materials, originate from natural sources or human activities. They naturally occur in rainwater, seawater, groundwater or soil and sometimes they are part of the natural cycle of the chemical and physical deterioration of stone. Salts originating from human activities can be linked to emissions from burning fossil fuels, agricultural activities, the use of road salt or cements. Salts are formed by the accumulation of ions in the wall or on the surface of specific parts of a building, e.g. plinths. The accumulation of ions can be due to soluble salts leaching out of building materials, soil, stone, wet or dry deposits from the atmosphere, but it can also be caused by the metabolism of micro-organisms or anthropogenic intervention.
