Pollution characteristics, potential source areas, and transport pathways of PM2.5 and O3 in an inland city of Shijiazhuang, China
AbstractRegional transmission plays a crucial role in the PM2.5 and O3 pollution of Shijiazhuang, a hot inland city in the North China Plain. To analyze the pollution pathways and potential source distribution, airflow backward trajectory cluster analysis, potential source contribution function (PSCF) method, and concentration-weighted trajectory (CWT) analysis were used adopting monitoring data from 2015 to 2021. The results showed that in 2016, the compound pollution days of PM2.5 and O3 were the most (24 days), accounting for 36.4% of the total. According to air mass backward trajectory analysis, the highest concentrati...

Health impact pathways related to air quality changes: testing two health risk methodologies over a local traffic case study
AbstractAir pollution causes damage and imposes risks on human health, especially in cities, where the pollutant load is a major concern, although the extent of these effects is still largely unknown. Thus, taking the busiest road traffic area in Portugal as a local case study (600 m × 600 m domain, 4 m2 spatial resolution), the objective of this work was to investigate two health risk methodologies (linear and nonlinear), which were applied for estimating short-term health impacts related to daily variations of high-resolution ambient nitrogen dioxide (NO2) concentrations modelled for winter and summer periods. Bo...

Short-term effects of exposure to cold spells on blood pressure among adults in Nanjing, China
AbstractShort-term effects of exposure to cold spells on blood pressure are still relatively limited, especially large-scale studies. Thus, we explored associations between cold spells and blood pressure using a large sample of Chinese adults. A total of 50,538 participants were included in our study. They are from Zhongda Hospital Health Screening Centre between 2019 and 2021. Data about the weather and air pollution were obtained from the relevant departments in Nanjing, respectively. We defined cold spells as mean apparent temperature (Tappmean) below the third or fifth percentile of the temperature distribution for 2 o...

Classification of aerosol types in mega-city of Lahore (Pakistan) using ground-based remote sensing
This study was aimed at classifying the aerosol types and assessing their temporal distribution in the atmosphere of Lahore. For this purpose, we utilized the particle linear depolarization ratio (PLDR) and single scattering albedo (SSA) from Aerosol Robotic Network (AERONET) version 3 inversion products. Datasets from AERONET stationed at Lahore were computed to obtain results. Based on the dust ratio (Rd) (obtained from SSA and PLDR) aerosols were classified into pure dust (PD), pollution aerosols: non-absorbing (NA), weakly absorbing (WA), moderately absorbing (MA), and strongly absorbing (SA) aerosols, and mixtures: po...

Using synthetic data to benchmark correction methods for low-cost air quality sensor networks
The objective of the network calibrations was to correct the 2000+ sensor measurements in the Netherlands for the sensitivity to (local) environmental conditions. The option to use real measurements was dropped because the number of low-cost sensors sufficiently close to the 40 reference measurement locations was assessed to be spatially insufficient to benchmark the proposed approaches. Instead, synthetic real concentrations were generated to enable validation at all sensor locations. Hourly actual sensor and actual fixed concentrations, as well as interpolated concentration maps, were used as underlying data to generate ...

Air quality changes during the COVID-19 pandemic guided by robust virus-spreading data in Italy
AbstractThis paper aims to assess the impact of restrictive measures against the COVID-19 spread on the air quality of the most representative urban centers in Italy during the 66 days of the first lockdown, integrating a broad and detailed set of socioeconomic and health data into machine learning techniques and correlation analysis. Hierarchical Clustering analysis applied to all 104 Italian provinces indicated a group of six provinces to represent the urban environment in Italy. In contrast, correlation analyses suggested two meteorological parameters and four other air quality parameters as the most skilful at expressi...

Examining the nexus between tourist arrivals and transportation sector-based emissions in Mediterranean countries: evidence from quantile regressions via method of moments
In this study, the impact of international tourist arrivals on CO2 emissions caused by transportation is investigated using the quantile regression via method of moments (MMQR) approach with data for the period 1995 –2019 from selected Mediterranean countries. Moreover, testing of tourism-induced environmental Kuznets curve (EKC) hypothesis is included in the analysis in terms of transportation sector-based pollution. The U-shaped correlation between economic growth and transportation sector-based emissions i n all quintiles is revealed, as well as tourist arrivals are found to increase emissions up to higher quintile le...

Smoke plume from fire Lagrangian simulation: dependence on drag coefficient and resolution
AbstractPlume rising from wildfire due to the buoyancy generated by the heat released from the fire is a crucial phenomenon to model for a correct description of smoke dispersion within the atmosphere. During the rise, the plume experiences the drag of external air which limits the rising itself. In this work, we investigate the dependence of the hybrid Eulerian-Lagrangian plume rise scheme embedded in the Lagrangian stochastic particle model SPRAY-WEB on the drag coefficient and on the horizontal resolution of the plume rise grid. We test four different drag coefficient models depending on the Reynolds number of the cells...

Randomized trial in rural Native American homes heated with wood stoves: results from the EldersAIR study
AbstractResidential wood burning has both practical and traditional values among many indigenous communities of the US Mountain West, although household biomass burning also results in emissions that are harmful to health. In a household-level three-arm placebo-controlled randomized trial, we tested the efficacy of portable filtration units and education interventions on improving pulmonary function and blood pressure measures among elder participants that use wood stoves for residential heating. A total of 143 participants were assigned to the Education (n = 49), Filter (n = 47), and Control (n = 47) arms. Blo...

Changing patterns for cardiovascular disease and subtypes mortality attributable to ambient fine particulate matter pollution between China and India during 1990 to 2019
AbstractLong-term trends in PM2.5-attributable cardiovascular diseases (CVDs) and subtypes mortality remain unclear between China and India, facing dual challenges of aging and severe air pollution. We aim to compare long-term trends and age-, period-, and cohort-effects changes in PM2.5-attributable CVD and subtypes mortality in China and India from 1990 to 2019. Data are derived from Global burden of disease 2019. Long-term trends and age-, period-, and cohort-effects changes were evaluated by join-point regression and age-period-cohort models. We found that in China, the age-standardized mortality rate in CVD potentiall...

Associations between dust exposure and hospitalizations in a dust-prone city, Lubbock, TX, USA
AbstractAlthough it is a growing area of investigation in the Global Dust Belt, only a few population-level studies have evaluated the human health associations of windblown dust in North America. We investigated whether acute, short-term dust exposures (DE), in Lubbock, Texas (a medium-sized, dust-prone city in the southern Great Plains, USA) were associated with significant increases in hospitalizations on the day of the exposure and up to 7 days afterward. We used the distributed lag non-linear models in time series analysis to describe non-linear relationship between response outcomes and the delayed effects of expos...
