Abstract
The growing production of urban solid waste is a structural problem faced by most cities around the world. The proliferation of mini-open dumps (MOD; small spontaneous open-air waste dumps formed in urban and peri-urban areas) on the banks of the Paraná River is particularly evident. During the historical drought (June-December 2021), we carried out sampling campaigns identifying MODs of the Santa Fe River, a secondary channel of the Paraná River. MOD were geolocated, measured, described and classified by origin. The distance to the river and other sensitive places was considered (houses-schools-health facilities). Our results suggested a serious environmental issue associated with poor waste management. MOD were extremely abundant in the study area, being mostly composed of domestic litter. Plastics clearly dominated the MOD composition. Burning was frequently observed as a method to reduce the volume of MOD. We concluded that the proliferation of MOD is a multi-causal problem associated with a failure of public policies and a lack of environmental education.
城市固体废弃物日益增多是世界上大多数城市都面临的结构性问题。在巴拉那河两岸,小型露天垃圾场(MOD;城市和城郊地区自发形成的小型露天垃圾场)的扩散尤为明显。在历史干旱期间(2021 年 6 月至 12 月),我们开展了取样活动,以确定巴拉那河次级河道圣菲河的 MOD。我们对 MOD 进行了地理定位、测量、描述并按来源分类。还考虑了与河流和其他敏感地点(房屋、学校、卫生设施)的距离。我们的研究结果表明,一个严重的环境问题与废物管理不善有关。研究区域内的 MOD 数量极大,主要由生活垃圾组成。塑料显然是 MOD 的主要成分。焚烧是减少 MOD 体积的常用方法。我们得出的结论是, MOD 的扩散是一个多方面造成的问题,与公共政策的失败和环境教育的缺失有关。
