BackgroundAlthough studies have provided estimates of premature deaths attributable to either heat or cold in selected countries, none has so far offered a systematic assessment across the whole temperature range populations exposed different climates. We aimed quantify total mortality burden non-optimum ambient temperature, and relative contributions from moderate extreme temperatures.MethodsWe collected data for 384 locations Australia, Brazil, Canada, China, Italy, Japan, South Korea,...
Background: Studies have examined the effects of temperature on mortality in a single city, country, or region. However, less evidence is available variation associations between and multiple countries, analyzed simultaneously. Methods: We obtained daily data 306 communities from 12 countries/regions (Australia, Brazil, Thailand, China, Taiwan, Korea, Japan, Italy, Spain, United Kingdom, States, Canada). Two-stage analyses were used to assess nonlinear delayed relation mortality. In first...
Abstract. PM2.5 samples were collected at a centrally located urban monitoring site in Seoul, Korea, every third day from March 2003 to December 2006 and analyzed for their chemical constituents. Sources identified using positive matrix factorization (PMF). A total of 393 obtained during the sampling period, 20 species measured. Nine source categories providing physically realistic profiles interesting insights into contributions ambient mass concentrations. The major contributors secondary...
Studies have shown that long-term exposure to air pollution such as fine particulate matter (≤2.5 μm in aerodynamic diameter [PM2.5]) increases the risk of all-cause and cardiovascular mortality. To date, however, there are limited data on impact specific diseases. This study aimed evaluate effects among residents Seoul, Korea.Healthy participants with no previous history disease were evaluated between 2007 2013. Exposure pollutants was estimated by linking location outdoor monitors ZIP code...
East Asian countries experience severe air pollution owing to their rapid development and urbanization induced by substantial economic activities. South Korea China are among the most polluted with high mass concentrations of PM2.5. Although occurrence transboundary neighboring has been recognized for a long time, studies involving simultaneous ground-based PM2.5 monitoring source apportionment in have not conducted date. This study performed daily Seoul Beijing from January December 2019....
While exposure to ambient fine particles <2.5 μm in aerodynamic diameter (PM2.5) has well-established health effects, there is limited quantitative evidence that links specific sources of PM2.5 with those effects. This study was designed examine the risks chemical species and source-specific mass on mortality Seoul, Korea, a highly populated city.We compare daily counts speciation data collected every 3 days, as well nine resolved by positive matrix factorization receptor model, from March...
Abstract Currently, we have limited knowledge of the physical and chemical properties emitted primary combustion aerosols changes in those caused by nucleation, condensation growth volatile species, particle coagulations under dilution cooling ambient air. A chamber was deployed to sample exhaust from a pilot-scale furnace burning various fuels at nominal heat input rate 160 kW/h−1 3% excess oxygen. The formation mechanisms particles smaller than 420 nm electrical mobility diameter were...
Abstract Fungi release spores into the global atmosphere. The emitted are deposited to surface of Earth by sedimentation (dry deposition) and precipitation (wet deposition), therefore contribute cycling substances. However, knowledge is scarce regarding diversities fungi from Here, an automatic dry wet deposition sampler high-throughput sequencing plus quantitative PCR were used observe taxonomic flux densities atmospheric fungal deposition. Taxon-specific velocities aerodynamic diameters...
Migraine is a chronic and agonizing neurological disorder prevalent worldwide. Although its pathogenesis remains unclear, limited evidence exists on the role of air pollution. We aimed to assess association short-term pollution exposure with migraine in conjunction synergistic effect temperature. identified 18,921 patients who visited emergency departments (EDs) for as primary disease Seoul from national database between 2008 2014. conducted time-stratified, case-crossover analysis compare...
