Type: article
Abstract: The research investigated the spatial distribution and concentrations of air pollutants, across six locations in Delta State, Nigeria which include two roadsides (Utagba-Unor junction, Obiaruku, and Umutu junction along Agbor-Abraka Road), two residential areas (Ebedei-Umueziogoli Quarters and Ebedei-Adonishaka), Ebedei-Unor near gas plant and a control site near the Ethiope River at Adonishaka. The ambient air quality of the locations were measured with Aeroqual Gas Monitoring Kit (ASTM D3249-95, 2011) with sampling done in the morning, afternoon, and evening period over seven consecutive days during the core of dry and wet seasons. The measured concentrations ranged obtained were CO (0.5 ± 0.07–3.29 ± 0.31 µg/m³), CO₂ (2.00 ± 0.04–7.39 ± 0.18 µg/m³), H₂S (0.00 ± 0.00–0.77 ± 0.12 µg/m³), NO (0.00 ± 0.00– 0.83 ± 0.06 µg/m³), NO₂ (0.14 ± 0.05–4.04 ± 0.35 µg/m³), and CH₄ (0.40 ± 0.06–4.33 ± 0.35 µg/m³). CO was observed to have the highest concentrations at Ebedei-Adonishaka, while Ebedei-Unor recorded the highest concentration of CO₂, H₂S, NO, NO₂, and CH₄. Seasonal variations was observed with more pollutant during the dry season compared to wet season.
