Illegal Dumping Sites in Bloemfontein, South Africa: Respiratory Symptoms, Risk Factors, and Community Perspectives

Illegal waste dumping is a significant global issue, particularly in low- and middle-income countries such as South Africa. This study aimed to investigate the risk factors for acute respiratory symptoms among residents living near illegal domestic waste dumping sites. The study also explored community perceptions regarding illegal dumping and its health effects. This cross-sectional study was conducted in Rocklands, Free State, South Africa, with 200 participants: 117 living within 0-5 km of a dumping site and 83 residing ≥5-10 km away. Data were collected using a structured questionnaire. Generalized linear models were employed to explore the relationship between proximity to illegal dumping sites and respiratory symptoms, adjusting progressively for confounders in successive models. Respiratory symptoms were more prevalent among those within 5 km of illegal dumping sites: cough (48.0% vs. 27.0%), shortness of breath (23.0% vs. 18.0%), wheezing (20.0% vs. 7.0%), and chest tightness (20.0% vs. 7.0%). Proximity was significantly associated with wheezing (PR: 2.77; 95% CI: 1.10-6.98) and chest tightness (PR: 2.86; 95% CI: 1.19-6.84). Community-driven initiatives, such as awareness campaigns and recycling, were strongly supported as solutions. These findings highlight the need for education on waste management. Collaborative efforts are essential to reduce illegal dumping and improve waste management.
