Analysis of environmental impacts resulting from the irregular disposal of construction and demolition waste in neighborhood Alto Bom Jesus in Serra Talhada–PE

Abstract

In Brazil, Civil Construction is a segment of great relevance for economic and social growth in Brazil. However, it is one of the sectors that cause environmental impacts in the country. Construction and Demolition Waste (CDW) are materials from constructions, renovations, repairs and demolitions of civil construction works, and those from the preparation and excavation of land (CONAMA, 2002). These materials are often found irregularly discarded in abandoned land, causing impacts to the environment. In the city of Serra Talhada, it was also possible to find in some regions the irregular disposal of construction and demolition waste, which causes several environmental and social problems. Therefore, the main objective of this study is to diagnose the environmental impacts caused by the deposition of construction and demolition waste in the Alto Bom Jesus neighborhood located in the municipality of Serra Talhada-PE. For this, bibliographical reviews were carried out on the subject, technical visits to the Alto Bom Jesus neighborhood, with the objective of cataloging the environmental impacts observed in the place and the elaboration of the Impact Matrix with a detailed analysis of the main environmental impacts observed in the area. Among the environmental impacts found are chemical and biological contamination and changes in the physical properties of soil and water; the change in air quality due to the presence of dust or gases; changes in the health and safety conditions of the population due to the appearance of disease vectors; change in landscape quality; increased municipality expenditures and impacts on shrubs, trees and animals that may be located near CDW disposal sites.
