Roles of Ambient Temperature and PM_2.5 on Childhood Acute Bronchitis and Bronchiolitis from Viral Infection.

ABSTRACT: Studies have associated the human respiratory syncytial virus which causes seasonal childhood acute bronchitis and bronchiolitis (CABs) with climate change and air pollution. We investigated this association using the insurance claims data of 3,965,560 children aged ≤ 12 years from Taiwan from 2006-2016. The monthly average incident CABs increased with increasing PM_2.5 levels and exhibited an inverse association with temperature. The incidence was 1.6-fold greater in January than in July (13.7/100 versus 8.81/100), declined during winter breaks (February) and summer breaks (June-August). The highest incidence was 698 cases/day at <20 °C with PM_2.5 > 37.0 μg/m³, with an adjusted relative risk (aRR) of 1.01 (95% confidence interval [CI] = 0.97-1.04) compared to 568 cases/day at <20 °C with PM_2.5 < 15.0 μg/m³ (reference). The incidence at ≥30 °C decreased to 536 cases/day (aRR = 0.95, 95% CI = 0.85-1.06) with PM_2.5 > 37.0 μg/m³ and decreased further to 392 cases/day (aRR = 0.61, 95% CI = 0.58-0.65) when PM_2.5 was <15.0 μg/m³. In conclusion, CABs infections in children were associated with lowered ambient temperatures and elevated PM_2.5 concentrations, and the high PM_2.5 levels coincided with low temperature levels. The role of temperature should be considered in the studies of association between PM_2.5 and CABs.

Project description:Rapid urbanization and consuming lifestyles have intensified air pollution in urban areas. Air pollution in megacities has imposed severe environmental damages to human health. Proper management of the issue necessitates identification of the share of emission sources. Therefore, numerous research works have studied the apportionment of the total emissions and observed concentrations among different emissions sources. In this research, a comprehensive review is conducted to compare the source apportioning results for ambient air PM2.5 in the megacity of Tehran, the capital of Iran. One hundred seventy-seven pieces of scientific literatures, published between 2005 and 2021, were reviewed. The reviewed research are categorized according to the source apportioning methods: emission inventory (EI), source apportionment (SA), and sensitivity analysis of the concentration to the emission sources (SNA). The possible reasons for inconsistency among the results are discussed according to the scope of the studies and the implemented methods. Although 85% of the reviewed original estimates identify that mobile sources contribute to more thant 60% of Tehran air pollution, the distribution of vehicle types and modes are clearly inconsistent among the EI studies. Our review suggests that consistent results in the SA studies in different locations in central Tehran may indicate the reliability of this method for the identification of the type and share of the emission sources. In contrast, differences among the geographical and sectoral coverage of the EI studies and the disparities among the emission factors and activity data have caused significant deviations among the reviewed EI studies. Also, it is shown that the results of the SNA studies are highly dependent on the categorization type, model capabilities and EI presumptions and data input to the pollutant dispersion modelings. As a result, integrated source apportioning in which the three methods complement each other's results is necessary for consistent air pollution management in megacities.Supplementary informationThe online version contains supplementary material available at 10.1007/s40201-023-00855-0.
