Assessment of Environmental and Public Health Risks of Unregulated Solid Waste Dumping: A Case Study of the Sidi Khalifa Temporary Landfill in Benghazi, Libya

Abstract

This study investigates the environmental and public health impacts of unregulated solid waste dumps in Benghazi, Libya, focusing on the Sidi Khalifa temporary landfill. Utilizing a mixed-method approach, including field surveys, interviews, and statistical analysis (SPSS), data were collected from 100 residents living near and far from the landfill. Results indicate significant environmental degradation, including air pollution from methane emissions (65% of respondents), foul odors (63%), and soil/water contamination (46–48%). Health impacts include respiratory issues (49%), frequent influenza (55%), and eye irritation (41%). Proximity to the landfill exacerbated these issues, with residents within 1 km reporting higher disease prevalence. The study underscores the urgent need for improved waste management policies, public awareness campaigns, and infrastructure development to mitigate risks. Recommendations emphasize stricter regulations, recycling initiatives, and community education to align with sustainable development goals.
