heal.abstract	The capillary rise effect on brickwork not located along the canals has been studied in previous works in Venice. In the present work, arguments concerning the capillary rise effects on brickwork along the canals are being dealt, vith. The research program has been developed on walls of different typologies, building materials, historical periods of construction, position and exposure orientation as well as different conditions of maritime traffic. Brick specimens from various points in height and in depth were sampled and underwent physical and chemical examination. In particular, soluble salt concentration, composition and distribution within the wall was determined by Atomic Absorption Spectrophotometry and Ionic Chromatography. Various salts present were identified by FT-IR, while TG-DTA was employed to identify thermal decomposition products. Porosity, as a significant physical parameter for the physico-chemical phenomena, was measured by a mercury porosimeter. The results conclude that the phenomenon of capillary rise is very advanced, due to higher values of soluble salts in comparison with walls not in direct contact with the canals, and mechanical action is increasing the integral porosity.	en
