Assessment of air pollution in crude oil producing communities of Ogbia in Bayelsa State, South-South, Nigeria

Ambient air quality was assessed in five crude-oil-producing communities—Imiringi, Otuasega, Emeyal, Otuoke and Ibelebiri—in Ogbia, Bayelsa State, Nigeria, to characterise seasonal pollution patterns and potential health implications. Using triplicate measurements from an Oceanus AQM-09 station over eight months, concentrations of PM2.5, PM10, CO, NO₂, SO₂ and O₃ were evaluated for dry and wet seasons. Dry-season PM2.5ranged from 153.53 ± 123.82 to 191.10 ± 122.72 µg m⁻3, while PM10 varied betwe
