Descarte irregular de resíduos sólidos no Rio Corrente: estudo de caso em trechos do perímetro urbano de Corrente-PI

Abstract

Solid waste has been considered one of the biggest environmental problems in the world and when it affects water resources many other problems occur, both environmental and social. With this, the present work aimed to diagnose the irregular disposal of solid waste in the flowing river along the urban perimeter of Corrente-PI. For this, 04 (four) on-site visits were carried out, these being to: measure the width of the river and verify the best point for waste collection, mark the geographic coordinates, fiction of the steel screen used to collect suspended solid waste in the rio, which was exposed on site for a period of 24 hours. And finally, the last visits that were to collect the drained material. In which, after applying the methodology, the drained waste went through 05 (five) stages: collection, segregation, drying and weighing to compose the gravimetry of the waste. After analyzing the data, the results show that the residues present in the river were glass (56.62%), plastic (21.31%), rubber (19.08%), metal (2.74%) and styrofoam (0 .25%), where these were further classified according to their potential risks to the health of the population and the environment, where the majority fell into class IIB inert and only plastic was class II A non-inert. The results also show that during the screen exposure period, a total of 940.60 grams of solid waste were collected, which was considered significant since they were collected in a natural resource, in which solid waste should not be discarded. However, the study concluded that the objective of the study was achieved, but highlights the need to carry out campaigns to raise awareness of the population, so that they do not dispose of waste inappropriately, as well as charging the public power so that cleaning services are efficient
