Abstract

Particulate matter has been on the rise in recent years owing to the activities of industries, population increases and other anthropogenic activities. Most recent data on PM2.5 in several cities in Gulf of Guinea reaches concentrations from moderate, to hazardous levels. This study is important because it provides better understanding on PM2.5 dynamics and concentrations from country to country which is key to strategizing towards achieving lower levels of PM2.5 in the ecosystem. Therefore, the aim of the study was to assess PM2.5 levels in atmospheric air samples in major cities (Podor, Fajara, Santa Maria, Ziquinchor, Accra, Agouenyive, Benin, Brazzaville, Kinshasa) in the Gulf of Guinea (GOG), using PurpleAir sensors network. The study showed that the cities in Senegal, Gambia Cabo Verde and Ziquinchor falls within the category of Good and Moderate standard for PM2.5 when compare to the USEPA air quality standard and guidelines (?35.4?g/m3). But for Accra, Togo, Nigeria Brazavile and Congo average monthly values were ?150.4?g/m3. Incidentally, these latter countries are where most of the oil exploration activities occur in the GOG.
