Africa, particularly West and North Africa, has some of the highest levels of average PM pollution, second only to South and East Asia and the Middle East. These areas, however, have the fewest air pollution monitoring stations per capita for either PM10 or PM2.5. While China and India have substantial air pollution problems, they also have at least moderate monitoring networks, with over 350 PM10 monitoring sites in India and over 1000 PM2.5 monitoring sites in China (although this is still well below per capita monitoring levels in developed countries in Europe, for example). In contrast, in all Africa, there are fewer than 150 PM10 and 50 PM2.5 monitoring stations, with Egypt and South Africa accounting for more than half of these stations, leaving the majority of the continent unmonitored. Outdoor air pollution is a risk factor for several of the world's leading causes of mortality, including stroke, heart disease, lung cancer, and respiratory disorders like asthma. This study reports the PM2.5 and PM10 concentrations and their emissions sectors in North Africa from 1990 to 2019. The data were collected online from the following platforms: EDGAR (Emissions Database for Global Atmospheric Research), Climate Watch, Our World in Data, and the World Bank. The analysis of data indicated that outdoor air pollution in North Africa is the 4th leading risk factor for death, with 3.4 million deaths in total from 1990 to 2019. The number of deaths related to outdoor air pollution in all the 5 North African countries has increased in 2019 compared to 1990. Tunisia, Algeria, and Egypt all had higher death rates in 1990 meaning they have since decreased; however, Morocco and Libya, have higher death rates in 2019, indicating that they had risen in recent decades. Globally, 43% of PM10 emissions in North Africa from 1970 to 2015, were contributed by buildings, 16.6% by other industrial combustion, 13.7% by transport, 11.4% by other sectors, 9.6% by agriculture, 5.3% by power industry, and 0.2% by waste. For PM2.5, the major emitter sector in North Africa, during the same period, was also buildings with 38.2%, followed by transport (21.5%), other industrial combustion (17.3%), other sectors (12.4%), power industry (6%), agriculture (4.5%) and waste (0.2%). The North African country with the highest numbers of PM2.5-attributable deaths is Egypt, followed by Algeria, Tunisia, Libya, and Morocco. But since 2010, except for Egypt which has kept its leading position, the ranking of the other 4 North African countries, according to the number of PM2.5 attributable deaths, have changed as follows: Morocco has climbed to the second position after Egypt, followed by Algeria, Libya, and Tunisia.
