A IMPORTÂNCIA DA AÇÃO DE GASES POLUENTES ATMOSFÉRICOS SOBRE O PATRIMÔNIO EDIFICADO E BENS INTEGRADOS BRASILEIROS CONSTITUÍDOS DE ROCHAS

Abstract

The gaseous pollutants in the atmosphere of cities have increased in recent decades and causing harm to humans, animals and plants, that is, life. They degrade and provide considerable losses to the heritage built and integrated assets, because exercise interaction with the surface of rocks constituents of these monuments. The builtheritages are a set of real estate and artistic elements. Many monuments are made of stones that have chemical compounds that interact with pollutants. The work deals with a literature review of studies developed by the EPA (United States Environmental Protection Agency) that describe what are the main pollutants of the atmosphere. The search looks for a correlation between the literature review and the conditions of the historic site. Evaluate the effects of the following pollutants: Sulfur dioxide, nitrogen oxides and particulate matter; and identified the most significant damage present in monuments.
