“…During the cold season in Fuzhou, heating is provided by lighting fires rather than using coal, which leads to increased PM emissions. The time series diagram also shows that there were more outpatient visits for respiratory diseases, including upper and lower respiratory diseases, during the cold season than the warm season, which may be different from the findings for other regions; for example, the spring dust storm season in Lanzhou may increase emergency room visits for respiratory diseases [29].…”

Background: Previous studies have suggested that there is an association between air pollutants and circulatory and respiratory diseases; however, relatively few have analyzed the association between air pollutants and outpatient visits based on the mortality, hospitalization rates, etc., especially in areas with relatively good air quality. Therefore, we conducted this study to research the association between air pollutants and outpatient visits in Fuzhou, China. Methods: We used a generalized linear Poisson model to study the association between air pollution and outpatient visits for respiratory and circulatory diseases from 2016 to 2018 in Fuzhou, China. Results: In the single pollutant model, nitrogen dioxide (NO 2) had a significant effect. For lag day 0 to lag day 5, the effect decreased with every 10 μg/L increase in NO 2. The daily maximum 8-h mean ozone (O 3-8h) and upper respiratory outpatient visits were positively associated during the cold period [lag2, excess risk (ER) (95% confidence interval (CI)): 1.68% (0.44-2.94%)], while O 3-8h and respiratory disease were positively associated during the warm period [lag5, ER (95% CI): 1.10% (0.11-2.10%) and lag4, ER (95% CI): 1.02% (0.032-2.02%)]. Similarly, particulate matter (PM) with an average aerodynamic diameter of less than 10 μm (PM 10) and lower respiratory diseases were positively associated during the warm period [lag0, ER (95% CI): 1.68% (0.44-2.94%)]. When the concentration of O 3-8h was higher than 100 μg/L, there was a positive effect on circulatory [lag5, ER (95% CI): 2.83% (0.65-5.06%)], respiratory [lag5, ER (95% CI): 2.47% (0.85-4.11%)] and upper respiratory [lag5, ER (95% CI): 3.06% (1.38-4.77%)] outpatient visits. The variation in O 3-8h changed slightly when we adjusted for other air pollutants, and after adjusting for O 3-8h, the ERs of the other air pollutants changed slightly. After adjusting for PM with an average aerodynamic diameter of less than 2.5 μm (PM 2.5), the ERs of the other air pollutants increased, and after adjusting for NO 2 , the ER of PM decreased.

Background: Previous studies have suggested that there is an association between air pollutants and circulatory and respiratory diseases, but relatively few have analyzed the association between air pollutants and outpatient visits considering mortality, hospitalization rates, etc., especially areas with relatively good air quality. Therefore, we conducted this study to research the association between air pollutants and outpatient visits in Fuzhou, China. Methods: We used a generalized linear Poisson model to study the association between air pollution and outpatient visits for respiratory and circulatory diseases during 2016-2018 in Fuzhou, China. Results: In the single pollutant model, nitrogen dioxide (NO2) had a significant effect. For lag day 0 to lag day 5, the effect decreased with every 10 µg/L increase in NO2. Daily maximum 8-h mean ozone (8-h O3) and upper respiratory outpatient visits were positively associated during the cold period [lag2, excess risk (ER) (95% confidence interval (CI)): 1.68% (0.44%-2.94%)], while 8-h O3 and respiratory disease were positively associated during the warm period [lag5, ER (95% CI): 1.10% (0.11%-2.10%) and lag4, ER (95% CI): 1.02% (0.032%-2.02%)]. Similarly, particulate matter (PM) with an average aerodynamic diameter of less than 10 μm (PM10) and lower respiratory diseases were positively associated during the warm period [lag0, ER (95% CI): 1.68% (0.44%-2.94%)]. When the concentration of 8-h O3 was higher than 100 μg/L, there was a positive effect on circulatory [lag5, ER (95% CI): 2.83% (0.65%-5.06%)], respiratory [lag5, ER (95% CI): 2.47% (0.85%-4.11%)] and upper respiratory [lag5, ER (95% CI): 3.06% (1.38%-4.77%)] outpatient visits. The variation in 8-h O3 changed slightly when we adjusted for the other air pollutants, and after adjusting for 8-h O3, the ERs of the other air pollutants changed slightly. After adjusting for PM with an average aerodynamic diameter of less than 2.5 μm (PM2.5), the ERs of the other air pollutants increased, and after adjusting for NO2, the ER of PM decreased. Conclusion: Exposure to ambient NO2, O3, PM2.5 and PM10 was associated with an increase in respiratory and circulatory system-related outpatient visits in Fuzhou, China.

“…While US-based studies are few, a recent analysis found a significant association between dust storms and increases in lagged non-accidental and cardiovascular mortality (Crooks et al 2016). Others have reported associations between dust storms and increased emergency room visits and hospitalizations due to asthma or chronic obstructive pulmonary disease, COPD (Kanatani, 2010;Tam et al 2012;Thalib and Al-Taiar, 2012;Ma et al 2016). Studies of exposure to Asian dust storm particles reported associations with decreased pulmonary function in adult asthmatics and increased reporting of lower respiratory tract symptoms (Watanabe et al 2015).…”

“…In arid regions, such as the Imperial Valley, the mobilization, transport and deposition of wind-blown dust can contribute to significant ecological, economic and health issues (Griffin et al 2001). Nonetheless, epidemiological studies on this emerging exposure remain limited and the health impacts of non-combustion related PM on communities, especially children and other vulnerable populations, are largely unknown (De Sario et al 2013;Ma et al 2016).…”

Changing weather patterns, droughts and competing water demands are dramatically altering the landscape and creating conditions conducive to the production of wind-blown dust and dust storms. In California, such factors are leading to the rapid shrinking of the Salton Sea, a 345 square mile landlocked "sea" situated near the southeastern rural border region known as the Imperial Valley. The region is anticipated to experience a dramatic increase in wind-blown dust and existing studies suggest a significant impact on the health and quality of life for nearby residents of this predominantly low-income, Mexican-American community. The discussion calls attention to the public health dimensions of the Salton Sea crisis. We know little about the possible long-term health effects of exposure to mobilized lakebed sediments or the numerous toxic contaminants that may become respirable on entrained particles. We draw on existing epidemiological literature of other known sources of wind-blown dust, such as desert dust storms, and related health effects to begin to understand the potential public health impact of wind-blown dust exposure. The increased production of wind-blown dust and environmental exposures to such non-combustion related sources of particulate matter are a growing health threat, due in part to drought coupled with increasing pressures on limited water resources. Recent population-based studies have linked dust storms with cardiovascular mortality, asthma hospitalization and decrease in pulmonary function in both adults and children. A growing number of studies provide evidence of the acute health effects of wind-blown dust exposures among children, which with repeated insults have the potential to influence respiratory health over time. The shrinking of the Salton Sea illustrates a public health and environmental justice crisis that requires action and attention to protect the health and well-being of local communities.
