Characterization Of Air Pollution By Pm2.5 And Black Carbon In An Urban Industrial Zone: Case Of Yopougon Industrial Zone, Côte D'ivoire

Air pollution from fine particulate matter (PM2.5) and black carbon (BC) represents a major public health challenge, particularly in urban industrial areas.This study was conducted in the Yopougon industrial zone of Abidjan, Côte d'Ivoire, to characterize the levels of these pollutants over a three-month period.PM2.5 concentration was assessed using the gravimetric method, while BC concentration was determined using the EEL Smoke Stain reflectometer (Model 43M, Diffusion Systems Ltd) from sampled filters.The results indicate that the average PM2.5 and BC concentrations were 46.48 µg/m³ (27.11-70.68µg/m³) and 55.26 µg/m³ (43.85-66.07µg/m³), respectively.These values exceed national standards and World Health Organization recommendations, highlighting the urgency of implementing mitigation measures to protect the population exposed to the harmful effects of air pollution.
