Avaliação dos impactos ambientais causados pelo processo de extração de argila, Corrente - PI

Abstract

Clay is a mineral of sedimentary rocks composed of very fine grains of aluminum silicates, associated with oxides that give them diverse shades and properties. They originate from a set of physical and chemical processes (very time consuming) that modify the rocks and alter their physical form and chemical composition. It has wide industrial application, the clay is mainly used in the manufacture of ceramic coatings, tableware, household utensils and decoration. From this antiquity man extracts natural resources. So it would be impossible for our day to day without them. The natives are a good example of this, since everything they ate and produced came from natural resources. A feature much used by them was the clay, they were used for the manufacture of pans and construction of houses without harming the environment. But nowadays with the great consumption of capitalist society and the growth of technological advances, companies want to produce more and more and with that they are damaging and destroying natural resources. The present work aims to demonstrate the impacts caused by the clay mining process and the manufacture of ceramic artifacts in a small ceramic industry in Corrente, Piauí. The ceramics studied is located in the city of Corrente, state of Piauí, but precisely Sincerino neighborhood, with the extraction site located at the exit to the nearby Riacho Frio municipality. The municipality of Corrente has a population of 26,084 inhabitants according to the census carried out by IBGE (meaning) in 015, with a territory of 3045.9 km2. With a population of 26,084 inhabitants according to a census carried out by the IBGE in 2015. For the evaluation of the environmental impacts of the production process of the ceramic industry, a photographic camera was used to register the existing activities, a notepad and an on-site visit to the ceramics in study. The ceramics industry was chosen because it met criteria that make the research feasible, such as: the receptivity of the owners, the visits made to observe the process and provide the necessary data for the accomplishment of the same. It was concluded that the stage that generates more damage to the environment is that of preparation and molding because it is the most time consuming and because it counts on several aspects that are very harmful not only the natural environment but also the health of the population contains emission of CO2 gases that causes in the human asthma and other respiratory problems besides contributing to global warming.
