“…In previous studies, the dose-response relationship between air pollution and diseases was mainly explored on the respiratory system. A population-based study in China suggested that the cut-off value of PM 2.5 was 83.0 μg/m 3 for the prediction of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) by ROC curves, which was higher than the corresponding value for PM 2.5 noted in the present study (61.165 μg/m 3 ) [47]. So it seemed that the interference of air pollution on maternal and fetal health may be more sensitive.…”

BackgroundMaternal exposure to air pollution is related to fetal dysplasia. However, the association between maternal exposure to air pollution and the risk of congenital hypothyroidism (CH) in the offspring is largely unknown.MethodsWe conducted a national database based study in China to explore the association between these two parameters. The incidence of CH was collected from October 1, 2014 to October 1, 2015 from the Chinese Maternal and Child Health Surveillance Network. Considering that total period of pregnancy and consequently the total period of particle exposure is approximately 10 months, average exposure levels of PM2.5, PM10 and Air Quality Index (AQI) were collected from January 1, 2014 to January 1, 2015. Generalized additive model was used to evaluate the association between air pollution and the incidence of CH, and constructing receiver operating characteristic (ROC) curve was used to calculate the cut-off value.ResultsThe overall incidence of CH was 4.31 per 10,000 screened newborns in China from October 1, 2014 to October 1, 2015. For every increase of 1 μg/m3 in the PM2.5 exposure during gestation could increase the risk of CH (adjusted OR = 1.016 per 1 μg/m3 change, 95% CI, 1.001–1.031). But no significant associations were found with regard to PM10 (adjusted OR = 1.009, 95% CI, 0.996–1.018) or AQI (adjusted OR = 1.012, 95% CI,0.998–1.026) and the risk of CH in the offspring. The cut-off value of prenatal PM2.5 exposure for predicting the risk of CH in the offspring was 61.165 μg/m3.ConclusionsThe present study suggested that maternal exposure to PM2.5 may exhibit a positive association with increased risk of CH in the offspring. We also proposed a cut-off value of PM2.5 exposure that might determine reduction in the risk of CH in the offspring in highly polluted areas.

“…Most probably the hospitalized patients were more vulnerable to the detrimental effect of air pollutants than community dwellers as they were more seriously ill and remained exposed to the ambient air (e.g., housing style, occupation, protection awareness) might also be explained by the differences in disease severity and management (30). Emergency visits for AECOPD increased shortly (lag 1 day) after increased level of PM 2.5 (8,10) while, the association between hospital admissions for AECOPD was positive for both PM 10 and PM 2.5 on lag day3 as shown in previous studies (4,6,11,31,32).…”

“…Several reports have shown associations between acute or chronic exposure to air pollution and morbidity or mortality (1)(2)(3). Previous studies have shown association between ambient air pollution exposure and clinical events such as emergency visit, hospital admission for respiratory diseases (4)(5)(6)(7)(8)(9)(10)(11), cardiovascular diseases (7,(12)(13)(14)(15)(16)(17)(18)(19), and cerebrovascular diseases (20). In addition, a number of studies have shown a connection between ambient air pollution exposure and non-accidental mortality (21)(22)(23)(24)(25)(26).…”

is one of the districts in Chiang Mai, Thailand facing high level of seasonal air pollution every year, the exposure of community dwellers to outdoor air pollutants 24 hours a day during seasonal smog period because of their open-air housing style, and agricultural occupational hazard. In addition, Chiang Dao hospital is the only available hospital serving the community with open-air wards; therefore we could certainly to identify the association between air pollution and mortality of hospitalized patients. Thus, the aim of this study was to determine the association between daily average seasonal air pollutants and daily mortality of hospitalized patients and community dwellers as well as emergency and hospitalization visits for serious respiratory, cardiovascular, and cerebrovascular diseases. Methods: This time series study was conducted between 1 March 2016 and 31 March 2017. The association of various air pollutant concentrations including particulate matter diameter less than 10 and 2.5 microns (PM 10 and PM 2.5), sulfur dioxide (SO 2), nitrogen dioxide (NO 2), carbon monoxide (CO), ozone (O 3) and daily mortality of hospitalized patients and community dwellers as well as relationship with frequencies of serious respiratory, cardiovascular, and cerebrovascular diseases were analyzed using a general linear model with Poisson distribution. Results: Only PM 2.5 was found to be associated with increased daily mortality of hospitalized patients (lag day 6, adjusted RR =1.153, 95% CI: 1.001-1.329), whereas PM 10 , PM 2.5 , NO 2 , and O 3 were associated with increased daily non-accidental mortality of community dwellers (lag day 0-7, adjusted RR =1.006-1.040, 95% CI: 1.000-1.074). For acute serious respiratory events; PM 10 and PM 2.5 were associated with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), while SO 2 , CO, and O 3 were associated with emergency visits for community-acquired pneumonia (CAP). O 3 was associated with emergency visits for heart failure (HF), NO 2 with emergency visits for myocardial infarction (MI), and SO 2 with hospitalized visits for cerebrovascular accident (CVA). Conclusions: Seasonal air pollutants were found to be associated with higher mortality among hospitalized patients and community dwellers with varying effects on severe acute respiratory, cardiovascular, and cerebrovascular diseases.

“…In light of these merits, there has been a growing interest in the development and deployment of WSNs that employ smart air quality sensors. A typical example is that China has deployed air quality WSNs in major cities (e.g., Shanghai and Beijing) [2,3]. With the help of wireless communicating technology, such as ZigBee, Wibree, and Sigfox, air quality in the WSNs deployed cities can be remotely tracked [1,[12][13][14].…”

Highlights A standalone-like smart device that can remotely track the variation of air pollutants in a power-saving way is created; Metal–organic framework-derived hollow polyhedral ZnO was successfully synthesized, allowing the created smart device to be highly selective and to sensitively track the variation of NO 2 concentration; A novel photoluminescence-enhanced Li-Fi telecommunication technique is proposed, offering the created smart device with the capability of long distance wireless communication. Abstract Remote tracking the variation of air quality in an effective way will be highly helpful to decrease the health risk of human short- and long-term exposures to air pollution. However, high power consumption and poor sensing performance remain the concerned issues, thereby limiting the scale-up in deploying air quality tracking networks. Herein, we report a standalone-like smart device that can remotely track the variation of air pollutants in a power-saving way. Brevity, the created smart device demonstrated satisfactory selectivity (against six kinds of representative exhaust gases or air pollutants), desirable response magnitude (164–100 ppm), and acceptable response/recovery rate (52.0/50.5 s), as well as linear response relationship to NO 2 . After aging for 2 weeks, the created device exhibited relatively stable sensing performance more than 3 months. Moreover, a photoluminescence-enhanced light fidelity (Li-Fi) telecommunication technique is proposed and the Li-Fi communication distance is significantly extended. Conclusively, our reported standalone-like smart device would sever as a powerful sensing platform to construct high-performance and low-power consumption air quality wireless sensor networks and to prevent air pollutant-induced diseases via a more effective and low-cost approach.
