“…The trajectories indicated potential areas impacted in northern Colombia. Results of studies of trajectories from North Africa showed the impact on the Caribbean atmosphere due to the Saharan dust episode ( Euphrasie-clotilde et al, 2020 ).

The restriction of mobility due to preventive social isolation has improved air quality in many regions of the world. At the same time, global and regional atmospheric phenomena such as biomass burning or dust transport from Sahara can exacerbate particulate matter (PM) mass. In this study, PM 10 and PM 2.5 concentrations were evaluated in industrial and urban areas during the lockdown period due to COVID-19 in northern Colombia. Aerosol Optical Depth (AOD) observations obtained from the spaceborne MODIS (MOD04-3k) and the active fire data was obtained from VIIRS Active Fire. We measured surface contamination at several stations to quantify the PM 10 and PM 2.5 changes associated with the general closure of anthropogenic and industrial activities driven by COVID-19 and by the macroscale and/or mesoscale contributions. In the industrial zone, a slight decrease in daily concentrations was detected at the stations located near the mining operations. In the urban area, the decrease is more salient in COVID-19 lockdown. A reduction rate in the daily averages of PM10 of 23.3%, 6.0%, and 19.0% was observed in the Sca, SBi, and SUn stations, respectively. The biomass burning episode has contributed 52% to the daily average of PM 10 and 45% to the daily average of PM 2.5 . The episode due to the passage of Saharan dust through the Caribbean Sea has contributed 79% to the daily average of PM 10 (150.75 μg/m 3 ) and on 57% to the daily average of PM 2.5 .

“…It has long been recognised that infectious diseases spreading through dust dispersion may also be responsible for adverse health effects resulting from dust inhalation, damaging protective mucosae and rendering individuals susceptible to bacterial infection (Terradellas et al, 2015). In addition to the link between Sahara dust and cardiovascular and respiratory diseases (Feng et al, 2019;Gurung et al, 2017;Momtazan et al, 2019), many epidemiological studies have also drawn the link with overall mortality and a range of infectious diseases (Venero-Fernández, 2016), demonstrating their damaging effects on health (Euphrasie-Clotilde et al, 2020). Cardiovascular mortality risk and acute paediatric asthma admissions could be increased by inhalation of desert dust (Domínguez- Rodríguez et al, 2021;Gyan et al, 2005).…”

“…Research shows that African dust influences air temperature (Plocoste et al, 2021;Plocoste and Pavón-Domínguez, 2020) and may also hinder the development of tropical cyclones (Plocoste and Pavón-Domínguez, 2020). In boreal summer, the Caribbean basin frequently experiences African dust outbreaks (Euphrasie-Clotilde et al, 2020;Plocoste et al, 2021). In June 2020, a very intense dust plume named "Godzilla" (Fig.…”

A massive amount of dust estimated at a million tons is released from the Sahara Desert each year into the atmosphere and travels over the North Atlantic Ocean, commonly referred to as the Saharan dust plume (SDP). With its ability to travel over very long distances across the sea, the SDP is of enormous global importance, affecting climatic processes, and playing a significant role in nutrient cycles, sedimentary cycles, and soil development. On the other hand, from an environmental health perspective, the SDP degrades air quality, posing serious health threats to humans, especially to people with lung conditions. Recent literature documents health issues, including respiratory and cardiovascular diseases and even death in extreme cases. Despite this knowledge, large uncertainties exist in our ability to predict future trends in Saharan dust emissions and model-projected atmospheric circulation patterns. Employing a comprehensive search of the recent literature, this study reviews present knowledge of the sources, composition and propagation dynamics of the SDP and the impact of its contained atmospheric particulates on health, ecosystems, and human activities to be able to formulate credible mitigation measures and unveil areas where further research is needed for improving on these formulations. A comprehensive list of the more recent references (mainly post-dating 2010) is assembled to aid the search process of those wanting to contribute to filling these important knowledge gaps.
