Implication

Study examines air pollutants' correlations with weather conditions in Abeokuta, highlighting seasonal health risks.

Key Points

  • This study aims to analyze the relationship between air pollutants and meteorological factors in Abeokuta over a 12-year period.
  • Averaged 12 years of hourly data (2012–2023) for PM2.5, PM10, NO2, SO2, CO, and O3.
  • Utilized regression analysis to investigate correlations with meteorological variables like temperature and humidity.
  • Calculated the Aggregate Air Quality Index (AAQI) and Health-Risk Adjusted AQI (HAQI) to evaluate air quality and health risks.
  • PM2.5 and PM10 consistently exceeded WHO standards, peaking during the Harmattan dry season.
  • Moderate to strong positive correlation found between pollutants and temperature (R² = 0.48–0.52).
  • HAQI indicated high health risks from PM2.5 exposure, with seasonal maxima exceeding 90.
