Abstract
This study evaluates selected inorganic contaminants and particulate matter in the atmosphere of specific Local Government Areas in Delta State, Nigeria, namely Warri, Uvwie, Udu, Okpe, and Ughelli. The contaminants examined include lead, ammonia, carbon monoxide, and particulate matter with diameters of 2.5 and 10 micrometers. Air samples were collected over a twelve-month period and analyzed for the presence of these substances. The results, presented as mean values from triplicate samples, indicated a consistent lead concentration of 0.001 gm across all months and local governments. Ammonia levels varied, ranging from 0.0080 to 0.070 gm, with specific monthly concentrations of 0.012 to 0.015 gm, 0.022 to 0.052 gm, and 0.058 to 0.088 gm. Particulate matter (PM2.5) concentrations ranged from 0.141 to 0.639 gm and 0.438 to 0.612 gm, while PM10 levels ranged from 0.202 to 0.987 gm and 0.763 to 0.991 gm across the months and local governments studied. The analysis of geo-accumulation and anthropogenic factors revealed that atmospheric contamination in these areas is primarily due to human activities.
