“…Desert dust is particularly rich in calcium carbonate, but contains little iron [178][179][180][181]. A solution of calcium carbonate shows alkalinity, so desert dust may act like an exfoliant to open skin pores and remove the epithelium, thus provoking cutaneous inflammation in patients with atopic dermatitis [177]. The results of Otani et al [182] provide preliminary evidence that Asian dust influences the allergic skin symptoms of healthy subjects, because the skin symptom scores were positively correlated with the suspended particulate matter level during dust events (p < 0.001).…”

“…Yang et al [176] observed an 11% increase in the risk of clinic visits for conjunctivitis during the Asian dust events, although this increase was not statistically significant. Exposure to Asian dust may contribute to the pathophysiology of allergic rhinoconjunctivitis as an adjuvant to antigenic pollens and fungal elements [177].…”

Dust storms and sandy dust events originating in arid and semi-arid areas can transport particulate material, pollutants, and potential transport long distances from their sources. Exposure to desert dust particles is generally acknowledged to endanger human health. However, most studies have examined anthropogenic particulate sources, with few studies considering contributions from natural desert dust. A systematic literature review was undertaken using the ISI Web of Knowledge and PubMed databases with the objective of identifying all studies presenting results on the potential health impact from desert dust particles across the world. This review reveals an imbalance between the areas most exposed to dust and the areas most studied in terms of health effects. Among the human health effects of dust storms are mortality and morbidity, arising from respiratory system, circulatory system, and other diseases. We summarize the quantitative results of current scientific health research and possible pathological mechanisms, and describe some of the many challenges related to understanding health effects from exposures to desert dust particles. Overall, for respiratory and circulatory mortality, both positive and negative associations have been reported for PM 10 of desert dust, but only a positive relationship was reported between PM 2.5-10 and mortality, and a positive relationship was also reported between PM 2.5 and human mortality. Future pathological studies should continue to focus on those mechanisms causing the most harmful effect of desert dust on respiratory and cardiovascular diseases. More attention should also be paid to the association between desert dust and the morbidity of other diseases, such as those affecting the reproductive system and nervous system.

Em segundo lugar, não foram incluídos como contagem de fatores de confusão pólen que estão associados com doenças atópicas [37][38][39] , como a sua associação com exacerbação da asma [40][41][42] . No entanto, análise dos efeitos específicos podem abranger implicitamente efeitos de flutuações sazonais nas concentrações de pólen e mofo ambiente.…”

RESUMOObjetivo: Foi investigada a associação entre diferenças horárias da poluição do ar e exacerbação da asma em Campo Grande, usando dados relacionados com internações por asma e verificada a sazonalidade e status socioeconômico com uma resolução temporal horária. Metodologia: Foi aplicado caso de cruzamento estratificada ajustado para o tempo; o atraso foi estratificado com 1 e 6, 7 e 12, We investigated the association between time differences of air pollution and exacerbation of asthma in Campo Grande, MS, using data related hospitalizations for asthma and verified seasonality and socioeconomic status with an hourly temporal resolution. Methodology: Stratified cross case was applied to set the time. It was laminated with the delay 1 and 6, 7, 12, 13, 18, 19 and 24, 25 and 48, and 49 and 72 h. Odds ratio (95% confidence interval), the interquartile range was increased after 19 and 24 h to O 3 . Results: The effect was lag 25 and 48 h in winter for ozone (O 3 ). The effects for O 3 were to the age of low socioeconomic status modified lag 7e12 h (1,252 (1:04 and 1:51)). The O 3 increased the risk of asthma exacerbations. Higher levels of O 3 were associated with increased risk of exposure of asthma exacerbations. Conclusions: The adverse effects of O 3 of the season were modified by age.The results indicate that health policy in the municipality should focus on vulnerable populations, such as people with asthma.

Several researchers in Japan have tried to evaluate the correlation between ASD event and Japanese cedar pollinosis [10,11]. …”

ObjectivesSince Korea is geographically close to China (the origin site for Asian sand dust [ASD]) the health influence of ASD event will be still greater in Korea. We aimed to evaluate the effect of PM10 (particulate matter with aerodynamic diameter <10 μm, below 150 μg/m3) on the clinical course of allergic rhinitis (AR).MethodsWe enrolled 47 healthy volunteers (group A) and 108 AR patients sensitized to house dust mites (group B). For 120 consecutive days (from February 1st to May 30th, 2012), all subjects reported their daily nasal symptoms and performed 2 peak flowmeter readings to measure peak nasal inspiratory flow (PNIF). We evaluated the correlation between the daily concentration of PM10, symptoms, and PNIF of patients. We also investigated changes in symptoms and PNIF 2 days before and after ‘dusty’ days (daily concentration of PM10 >100 μg/m3)ResultsThere was no significant difference between group A and B in nasal symptoms and PNIF during the 120-day period. Changes in nasal symptoms and PNIF were not statistically significant before or after a PM10 concentration rise above 100 μg/m3.ConclusionLow concentration PM10 does not have significant effect on nasal symptoms and PNIF in AR patients.
