Resíduos sólidos: percepção e geração no ambiente doméstico

Abstract

Pollution is a subject still not yet discussed among people in cities community and in educational institutions in the West border of Rio Grande do Sul. Considering this fact, it is important to evaluate human actions in the process of environmental degradation. In this sense, the objective of this paper was to evaluate the level of people's perception of the pollution in the urban area of the municipality of Itaqui, in addition to characterizing and quantifying the domestic waste produced by families in the region, highlighting the main problems encountered and their causes. For this, two researches were carried out, the first one sought to evaluate the level of people's perception of the pollution present in the urban area of the city of Itaqui, highlighting the main problems found. The variables, pollution level, air quality and water quality were evaluated. The second aim was to characterize and quantify domestic waste produced in the family environment. For this research, students from the first and third semesters of Agronomy and Interdisciplinary Bachelor of Science and Technology courses, enrolled in the curricular component of Environmental Science and Ecology, were invited and challenged to separate the domestic waste produced in a period of one week (the seven days a week), and quantify these residues by type and by each family component. The results found allow us to observe that the interviewed residents perceive the presence of pollution in the urban space and classify it at the medium level, according to the scale elaborated, considering Bad (0 to 3) Regular (4 to 7) and Good (8 to 10). It is also noted that the average value produced from organic waste was 0.434 kg, with 1.598 and 0.083 kg being the highest and the lowest value found, respectively, while the average value produced from solid waste was 0.278 kg, with 1.074 and 0.048 kg being the highest and the lowest value found, respectively.
