Large Brazilian cities, such as Rio de Janeiro, suffer serious environmental problems caused by informal settlements (IS), such as advances in the degradation of surface waters involving anthropic pressures resulting from uncontrolled urban growth, lack of sanitation or disasters related to climate events, creating a gap in relevant information about environmental health in urban IS. Therefore, it is essential to assess the health conditions of IS and the local population's perception of their living conditions. This study aimed to evaluate, by online form and public data, the sanitary conditions of the third largest IS in Brazil, the Rio das Pedras community, which was located on the banks of the Jacarepaguá Lagoon complex. The analysis revealed that 35% of respondents reported releasing domestic sewage directly into the river near their homes. Furthermore, 83% of the participants reported that they disposed of urban solid waste inappropriately. About 21% of residents reported falling ill due to direct contact with unsafe water after flood events. Public managers, concerned with advancing sustainability agendas and mitigating the risks to environmental health related to the lack of adequate sanitation services, should invest in actions that reflect the perception of the local population, proposing more appropriate socio-environmental solutions.

巴西的大城市，如里约热内卢，遭受着由非正规住区（IS）引起的严重环境问题，例如地表水退化的加剧，其中涉及因城市增长失控、卫生设施缺乏或与气候事件有关的灾害造成的人为压力，造成城市信息系统环境健康相关信息的空白。因此，有必要评估IS的健康状况以及当地居民对其生活条件的看法。本研究旨在通过在线表格和公共数据评估巴西第三大伊斯兰国——位于 Jacarepaguá 泻湖综合体岸边的 Rio das Pedras 社区的卫生状况。分析显示，35%的受访者表示将生活污水直接排入自家附近的河流中。此外，83%的参与者表示，他们处理城市固体废物的方式不当。大约 21% 的居民报告称，洪水事件后因直接接触不安全的水而生病。关心推进可持续发展议程并减轻因缺乏足够的卫生服务而造成的环境健康风险的公共管理者应投资于反映当地居民看法的行动，提出更合适的社会环境解决方案。
