| Abstract: Urban air quality is deteriorating with increased pollutant concentrations due to anthropogenic activities. The study examined spatial and seasonal variations of particulate matter (PM₂.₅ and PM₁₀), nitrogen dioxide, sulfur dioxide and ozone from 2018-2023 at Bhiwadi and Udaipur monitoring stations, and assessed their relationships with meteorological parameters. Results showed that monthly and annual mean concentrations of all pollutants, except O₃, consistently peaked in both cities, attributed to rapid industrialization and urbanization. Seasonal variations observed higher pollutant concentrations during winter, followed by pre-monsoon, post-monsoon, and lower in monsoon seasons. In Bhiwadi and Udaipur, highest mean concentrations of PM₂.₅ (55.71 and 31.2 μg/m³), PM₁₀ (210 and 178 μg/m³), NO₂ (52 and 45 µg/m³), SO₂ (69.20 and 20.49 µg/m³), and O₃ (46.94 and 49.93 μg/m³) were recorded, respectively. The wind speed and direction were the strongest influences on pollutant concentrations. Correlation and regression analyses indicated significant relationships between pollutants and meteorological parameters. These findings led in designing and implementing season-specific air pollution mitigation strategies at the regional scale. Implementation of precautionary measures is essential to reduce pollutant exposure to the public. This investigation further suggests that extensive studies on adverse impacts of air pollution on human health and environmental risk assessment are required. |
