Resumo
O sistema de transporte do Brasil é caracterizado pelo seu sistema rodoviário abundante, existindo as vias pavimentadas e não pavimentadas, também conhecidas como estradas de terra. Entre essas vias não pavimentadas, a emissão de poeira gerada pela passagem de veículos é uma das principais preocupações tanto para o setor agropecuário quanto para a população local.
Além dos potenciais riscos à saúde humana, também deve-se levar em consideração os impactos ambientais gerados e os danos ao desenvolvimento de plantações. Existem várias soluções no mercado atualmente para combater essas emissões, conhecidas como Supressores de Poeira, sendo compostas por soluções aquosas aplicadas nas superfícies das vias. Alguns exemplos
desses supressores são a água, os produtos orgânicos e os à base de petróleo. Neste trabalho buscou-se caracterizar e comparar diferentes métodos de supressores de poeira, simulando condições climáticas semelhantes ao local de coleta de amostras de solo, utilizando o equipamento túnel de vento. O ponto de foco do estudo é a comparação da eficiência do uso de
um polímero sintético com as amostras de solo puro e solo com água. As comparações de eficiências dos supressores neste trabalho mostram que o polímero sintético apresentou melhores resultados para redução da poeira, pois possui menor dano ambiental em comparação com as demais alternativas e também por demonstrar ser mais eficiente do ponto de vista de controle da emissão de poeira. Nos testes realizados atualmente, são observadas um destaque na eficiência do uso do polímero sintético como uma alternativa pelo seu desempenho de supressão comparadas aos diferentes métodos também estudados, proporcionando uma redução de 93,66% de particulados em relação ao solo puro e uma redução de 90,78% em relação ao método qual utiliza-se água.
The Brazil’s transportation system is characterized by its abundant roadway network, existing the paved roads and non-paved roads, also known as dirt roads. Between these nonpaved roads the dust emission generated by the passage of vehicles is one of the main concerns so much of the farming sector as much as the local population. Besides the potential health risks for the human body of the residentes, it need to be taken into account of the environmental impacts as one of its consequences is damages to crops used for comerce. Currently it exists many solutions on the Market to combat agaisnt these emissions called Dust Suppressors, being composed by aqueous solutions, aplied on the pavement. Some examples of these suppressors are water, organic products or petrol based ones. In this Thesis it was created a methodology for the description and comparation of diferent methods of dust suppressors, simulating the climate conditions similar to the location where it was collected the soil samples using the wind tunnel. The point of focus of the study will be the comparison of the efficiency of the use of a synthetic polymer to the other forms of suppression, creating many soil samples containing pure soil, soil with water, and soil with polymer as basis for the comparation. The results prediction of the comparison of the suppressors efficiency for this thesis shows that the synthetic polymer presented better results for the reduction of dust, not only for your efficiency but also for its reduction of environment impact as others would and for its low cost of applications both in the ammount applied and the time required for its reapplication. In the tests currently performed, its observed na emphasis on the efficiency of the use of the synthetic Polymer as an alternative due to its performance of suppression compared to the diferent methods studied also, providing a reduction of 93,66% of particulates in regard to the pure soil, and a reduction of 90,78% regrading to the method using water.
