The aim of the study was to assess community knowledge, practices, and environmental risks associated with residential asbestos exposure in low-middle income neighborhoods of Cartagena, Colombia. In a cross-sectional survey, 305 residents from 30 asbestos-affected neighborhoods completed questionnaires on asbestos knowledge and practices. Environmental samples (roofing, dust, and water) were analyzed for asbestos fibers. Asbestos-cement roofing was present in 87.5% of homes. While 55.8% recognized asbestos hazards, 52% routinely disturbed asbestos materials, and informal disposal was common. Socially embedded practices, such as repurposing asbestos sheets and improper disposal were common. Asbestos fibers were found in 90% of dust samples and 85% of rainwater samples. Residential asbestos exposure remains a major health risk in these communities. Mitigation requires not only education but also improved policies for safe removal and replacement of asbestos materials.
