Overview

Observational analysis identifies high PM 2.5 levels in Ibadan households, suggesting a need for improved air quality monitoring systems.

Key Points

  • Daily median PM 2.5 concentrations reached up to 109.3 µgm −3 outdoors during the dry season.
  • Among indoor and outdoor measurements, 90% of PM 2.5 variance can be attributed to outdoor sources.
  • Phase I employed 24 Atmotube PRO sensors in 12 households, capturing fluctuations in PM 2.5 concentrations.
  • Findings highlight the exceedance of WHO interim target for PM 2.5, underscoring the health risks posed.
