“…The study population and exposure assessment have been fully described elsewhere. 8 In brief, 1,068 women were enrolled successively in the Timoun cohort during their third trimester prenatal visit, between 2004 and 2007. The participants were representative of pregnant women giving birth in the local public hospitals, which accounts for 70% of all deliveries in Guadeloupe.…”

“…[2][3][4][5] Although an increasing number of studies have shown that maternal exposure to air PM can affect the developing fetus (resulting in, among other outcomes, small for gestational-age [SGA] births), 6 available evidence on the effects of dust outbreaks on pregnancy is very scarce. 7,8 We aimed to investigate the impact of Saharan dust episodes on severe SGA births among a population of pregnant women in the French Guadeloupe archipelago (an outermost region of the European Union situated in the Caribbean basin) using prospectively collected individual data.…”

Desert dust transported from the Sahara to the Caribbean generates peak exposures to particulate matter £ 10 μm (PM 10). We investigated the impact of dust episodes on severe small for gestational-age births in Guadeloupe. The study sample consisted of 911 pregnant women enrolled in the Timoun mother-child cohort. Desert dust exposure was assessed through the mean daily PM 10 concentrations averaged over the entire pregnancy. Numerous sociodemographic and medical risk factors were considered as covariates and introduced into multinomial logistic regression models. Odds ratios (ORs) were calculated per SD change (3.08 μg/m 3). Among various outcomes, symmetrically growth-retarded births showed the highest OR (3.28, 95% CI: 1.08-10.02). Saharan dust seems to influence weight but not length or head circumference at birth. Given the high OR observed in this study, it is conceivable that Saharan dust plays a role through severe placental insufficiency early in pregnancy.

“…Six articles discussed the long-term adverse health effects caused by dust storms by means of different outcomes, like reduced birth weight, baby’s birth weight <2.5 Kg, gestation/gestational age >37 weeks and premature birth, 32 and decreased cognitive function in children. 33 Preterm births 34 were correlated with Valley fever incidences 36 and increased spring measles incidence. 44 Only one article was observed to indicate no significant effect of desert dust storms on pregnancy consequences.…”

Background: Dust storms and their impacts on health are becoming a major public health issue. The current study examines the health impacts of dust storms around the world to provide an overview of this issue. Method: In this systematic review, 140 relevant and authoritative English articles on the impacts of dust storms on health (up to September 2019) were identified and extracted from 28 968 articles using valid keywords from various databases (PubMed, WOS, EMBASE, and Scopus) and multiple screening steps. Selected papers were then qualitatively examined and evaluated. Evaluation results were summarized using an Extraction Table. Results: The results of the study are divided into two parts: short and long-term impacts of dust storms. Short-term impacts include mortality, visitation, emergency medical dispatch, hospitalization, increased symptoms, and decreased pulmonary function. Long-term impacts include pregnancy, cognitive difficulties, and birth problems. Additionally, this study shows that dust storms have devastating impacts on health, affecting cardiovascular and respiratory health in particular. Conclusion: The findings of this study show that dust storms have significant public health impacts. More attention should be paid to these natural hazards to prepare for, respond to, and mitigate these hazardous events to reduce their negative health impacts.

“…In addition to their global climate and ecosystem impact [95], they have been associated with adverse health effects, including cardiorespiratory mortality and morbidity [96]. Recently, Viel et al [97] also evidenced an increasing risk of preterm births with the levels of PM10 and the frequency of intense Saharan dust events over Guadeloupe Island.…”

The CARA program has been developed since 2008 by the French reference laboratory for air quality monitoring (LCSQA) and the regional monitoring networks to gain a better knowledge at the national level on the particulate matter (PM) chemistry and its diverse origins in urban environments. It results of strong collaborations with international-level academic partners, allowing to bring state-of-the-art, straightforward and robust results and methodologies within operational air quality stakeholders (and subsequently, decision makers). Here, we illustrate some of the main outputs obtained over the last decade thanks to this program, regarding methodological aspects (both in terms of measurement techniques and data treatment procedures) as well as acquired knowledge on the predominant PM sources. Offline and online methods are used following well-suited quality assurance and quality control procedures, notably including inter-laboratory comparison exercises. Source apportionment studies are conducted using various receptor modeling approaches. Overall, the results presented herewith underline the major influences of residential wood burning (during the cold period) and road transport emissions (exhaust and non-exhaust ones, all along the year), as well as substantial contributions of mineral dust and primary biogenic particles (mostly during the warm period). Long-range transport phenomena, e.g., advection of secondary inorganic aerosols from the European continental sector and of Saharan dust into the French West Indies, are also discussed in this paper. Finally, we briefly address the use of stable isotope measurements (δ15N) and of various organic molecular markers for a better understanding of the origins of ammonium and of the different organic aerosol fractions, respectively.
