“…NO 2 and SO 2 concentration, but not PM 10 , were associated with increased prevalence of AR among kindergarten children in seven cities in Liaoning Province during 2007–2008 [21]. In addition, a study in Changsha (China) showed that the prevalence of AR in children was significantly positively correlated with age-related accumulative personal exposure of PM 10 , SO 2 , and NO 2 [22]. …”

With the continuous rapid urbanization process over the last three decades, outdoors air pollution has become a progressively more serious public health hazard in China. To investigate the possible associations, lag effects and seasonal differences of urban air quality on respiratory health (allergic rhinitis) in Changchun, a city in Northeastern China, we carried out a time-series analysis of the incidents of allergic rhinitis (AR) from 2013 to 2015. Environmental monitoring showed that PM2.5 and PM10 were the major air pollutants in Changchun, followed by SO2, NO2 and O3. The results also demonstrated that the daily concentrations of air pollutants had obvious seasonal differences. PM10 had higher daily mean concentrations in spring (May, dust storms), autumn (October, straw burning) and winter (November to April, coal burning). The mean daily number of outpatient AR visits in the warm season was higher than in the cold season. The prevalence of allergic rhinitis was significantly associated with PM2.5, PM10, SO2 and NO2, and the increased mobility was 10.2% (95% CI, 5.5%–15.1%), 4.9% (95% CI, 0.8%–9.2%), 8.5% (95% CI, −1.8%–19.8%) and 11.1% (95% CI, 5.8%–16.5%) for exposure to each 1-Standard Deviation (1-SD) increase of pollutant, respectively. Weakly or no significant associations were observed for CO and O3. As for lag effects, the highest Relative Risks (RRs) of AR from SO2, NO2, PM10 and PM2.5 were on the same day, and the highest RR from CO was on day 4 (L4). The results also indicated that the concentration of air pollutants might contribute to the development of AR. To summarize, this study provides further evidence of the significant association between ambient particulate pollutants (PM2.5 and PM10, which are usually present in high concentrations) and the prevalence of respiratory effects (allergic rhinitis) in the city of Changchun, located in Northeastern China. Environmental control and public health strategies should be enforced to address this increasingly challenging problem.

Impact of microbial air quality in preschools on paediatric respiratory health

Microbial air quality (MAQ) is unambiguously linked with one's health particularly in pulmonology. Children remain more vulnerable in acquiring airborne infections than adults. MAQ studies and management are being implemented in developed countries, yet such information and actions are scarce in developing countries. Herein, we aimed to determine the indoor and outdoor airborne microbial concentrations in a rural versus urban perspective and their association with paediatric respiratory health. Preschools, one representing an urbanized and the other, a rural area, from Kandy, Sri Lanka, were considered. Respiratory health of 146 children (age; 3-6 years) was examined, and questionnaire-based information was obtained from their parents. Air samples were taken using natural sedimentation, single-stage viable sampler and fine particulate sampler to calculate the total microbial and culturable counts. Inhalation dose rates were calculated as per standard reference values. Microorganisms were identified using 16SrRNA sequencing. Accordingly, 57.97% (n = 40) urban and 31.17% (n = 24) rural subjects suffered from at least one respiratory disease, upper respiratory tract infections, rhinitis, wheeze, etc. High total microbial counts (cells/m 3) were seen in urban preschool (indoor: 4.66 × 10 5 vs. 2.45 × 10 5 , outdoor: 4.29 × 10 4 vs. 2.74 × 10 4). Inhalation dose rates were high in urban preschool, both indoor and outdoor (2.00 × 10 4 and 1.05 × 10 4 cells/kg day). Irrespective of the site, indoor microbial counts were high and majority were opportunistic pathogens: Pseudomonas stutzeri, P. fluorescens, P. putida, Brevundimonas diminuta, Enterobacter cloacae, Bacillus pumilus, Acinetobacter calcoaceticus, B. cereus, Pseudoescherichia vulneris and Morganella morganii. Accordingly, observed dynamics can be a risk factor for the higher respiratory disease prevalence seen among urban preschoolers.
