Measuring Air Quality for Advocacy in Africa (MA3): Feasibility and practicality of longitudinal ambient PM2.5 measurement using low-cost sensors

Ambient air pollution in urban cities in sub-Saharan Africa (SSA) is an important public health problem, given the magnitude of health effects attributable to the latter. On most global air quality index maps, however, information about ambient pollution from Africa is scarce. African physicians with interest in air quality monitoring (AQM) thus set out to evaluate the feasibility and practicality of longitudinal ambient PM2.5 measurement using Purple Air-II-SD device, a low-cost AQM sensor, with the aim of assessing the efficiency of its data recovery rate, comparing averages and identifying challenges experienced.
