THE INFLUENCE OF THE URBAN ENVIRONMENT ON THE STONE OF THE ARENA IN PULA

Abstract

The paper presents data on quantity of sulphate, chloride and metals in stone samples from the Vinkuran quarry and stone blocks from the external curved wall of the Arena in Pula. It has benn established that the stone from the Vinkuran quarry contains insignificant content of primary soluble salts (sulphates and chlorides) and parts of metal. A considerable increase in concentration of sulphates (to 92 times), as well as chlorides and metals, particularly lead (to 36 times), has been noticed in the surface layer of stone from the external curved wall of the Arena.
