Title: Toxic Trajectories: Modeling Heavy Metal-Laden Phosphate Dust Dispersion and Multi-Receptor Health Risks Near Kpémé’s Industrial Zone
Journal: Results in Engineering
Summary:
This study presents an environmental modeling approach to trace the dispersion of phosphate dust contaminated with heavy metals from industrial activities in Kpémé, Togo. Using advanced atmospheric and geographic modeling tools, the research evaluates how toxic particles travel and affect various environmental and human receptors. The findings reveal elevated risk zones, highlighting vulnerable populations and ecosystems exposed to chronic contamination. The work contributes to industrial pollution management and public health risk assessment by offering a spatially explicit framework for multi-receptor analysis.
