Abstract
The study identified the impacts of air pollutants and their relationships with meteorological parameters. Pollutants generated from road construction and use compared with WHO and Ghana Standards Authority (GSA) guidelines revealed the median of PM10 (76µg/m3), PM2.5 (26.1µg/m3), NO2 (36µg/m3), SO2 (236 µg/m3), noise (75dBA) at Somanya sampling location were above the WHO guidelines for air quality. Whiles PM10, SO2, and noise were above the (GSA) permissible limits. The Mataheko location had median values of PM10 (100.4 µg/m3), PM2.5 (24.9µg/m3), NO2 (41.0 µg/m3), SO2 (26 µg/m3), noise (75.5 dBA) above the WHO limits, whereas only noise and PM10, were above the GSA limits for ambient air quality. Construction activities released PM10, PM2.5, NO2, SO2, and noise above WHO and GSA limits. Though the quantities detected are not directly comparable to air quality recommendations, which are based on 24-hour or annual averages, they raise concerns about public health and policy.
