Background: Winds from the Sahara-Sahel desert region regularly transport large amounts of dust to the Americas, North Africa, and Europe. The presence of high dust concentrations for long periods of time, and the interaction between dust and man-made air pollution, raise concerns about adverse health effects and appropriate interventions by health authorities. This study tested the hypothesis that outbreaks of Saharan dust exacerbate the effects of man-made pollution, specifically fine and… 

Saharan Dust and Associations between Particulate Matter and Daily Mortality in Rome, Italy

Evidence is found of effects of PM2.5–10 and PM10 on natural and cause-specific mortality, with stronger estimated effects on cardiac mortality during Saharan dust outbreaks, to be taken into account in air quality standards.

Saharan dust, particulate matter and cause-specific mortality: a case-crossover study in Barcelona (Spain).

Particulate matter concentrations during desert dust outbreaks and daily mortality in Nicosia, Cyprus

Investigating the effects of PM10 on total non-trauma, cardiovascular and respiratory daily mortality in Cyprus between 1 January 2004 and 31 December 2007 suggests adverse cardiovascular effects associated with desert dust events.

Saharan dust and association between particulate matter and case-specific mortality: a case-crossover analysis in Madrid (Spain)

Evidence of strongest effects of particulate matter during Saharan dust days is found, providing a suggestion of effect modification, even though interaction terms were not statistically significant.

Health effects from Sahara dust episodes in Europe: literature review and research gaps.

Effect of atmospheric mixing layer depth variations on urban air quality and daily mortality during Saharan dust outbreaks.

Desert Dust Outbreaks in Southern Europe: Contribution to Daily PM10 Concentrations and Short-Term Associations with Mortality and Hospital Admissions

PM10 originating from the desert was positively associated with mortality and hospitalizations in Southern Europe, and policy measures should aim at reducing population exposure to anthropogenic airborne particles even in areas with large contribution from desert dust advections.

Does the presence of desert dust modify the effect of PM10 on mortality in Athens, Greece?




Air pollution and daily mortality in the Coachella Valley, California: a study of PM10 dominated by coarse particles.

The findings provide evidence for a mortality effect of PM10 in an area where the particulate mass is dominated by coarse particles, and are robust to various model specifications, correction for autocorrelation and overdispersion.

Effects of the Asian dust events on daily mortality in Seoul, Korea.

The results provide weak evidence that the Asian dust events are associated with risk of death from all causes, but the association between the dust events and deaths from cardiovascular and respiratory causes was stronger and it suggests that persons with advanced cardiovascular and lungs disease may be susceptible to the Asiandust events.

Coarse and fine particles and daily mortality in the Coachella Valley, California: a follow-up study

Many epidemiological studies provide evidence of an association between ambient particles, measured as PM10, and daily mortality. Most of these studies have been conducted in urban areas where PM10

Episodes of high coarse particle concentrations are not associated with increased mortality.

It is concluded that coarse particles from windblown dust are not associated with mortality risk in six U.S. cities.

Events affecting levels and seasonal evolution of airborne particulate matter concentrations in the Western Mediterranean.

Time series of levels of PM (PM10 and TSP) and gaseous pollutants recorded in air quality monitoring networks from Northeastern Spain were interpreted using meteorological data and satellite observations of African dust plumes to identify the processes affecting time variations of PM levels on a day-to-day and seasonal basis.

Associations between air pollution and mortality in Phoenix, 1995-1997.

Factor analysis revealed that both combustion-related pollutants and secondary aerosols (sulfates) were associated with cardiovascular mortality, and detailed PM composition data was used in a time-series analysis of mortality.

Epidemiological evidence of effects of coarse airborne particles on health

It is concluded that special consideration should be given to studying and regulating coarse particles separately from fine particles, suggesting that coarse PM may lead to adverse responses in the lungs triggering processes leading to hospital admissions.
