Publikováno v: Atmospheric Pollution Research. 12:243-260
In spite of the global outcry for urgent action against air pollution, most African countries lack functional air quality monitoring stations and data there from; making air quality management difficult. Therefore, stand-alone studies are reviewed to

Publikováno v: Atmospheric Environment. 244:117978
The concentrations of nitrogen dioxide (NO2), sulfur dioxide (SO2) and ozone (O3) were determined at 20 locations (10 urban and 10 rural) in both indoor (cooking areas) and ambient air in the Nsukka area during two one-week sampling periods in both d
