Numerical Simulation to Air Pollution Emission Control near an Industrial Zone

open access: yesAdvances in Mathematical Physics, 2017
A rapid industrial development causes several environment pollution problems. One of the main problems is air pollution, which affects human health and the environment. The consideration of an air pollutant has to focus on a polluted source.

Effects of Ground Heating on Ventilation and Pollutant Transport in Three-Dimensional Urban Street Canyons with Unit Aspect Ratio

open access: yesAtmosphere, 2019
A validated standard k-ε model was used to investigate the effects of ground heating on ventilation and pollutant transport in a three-dimensional (3D) street canyon.

Spatiotemporal patterns of the fossil-fuel CO2 signal in central Europe: results from a high-resolution atmospheric transport model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The emission of CO2 from the burning of fossil fuel is a prime determinant of variations in atmospheric CO2. Here, we simulate this fossil-fuel signal together with the natural and background components with a regional high-resolution atmospheric ...

The Impact of Sustained Exposure to Air Pollutant on the Mental Health: Evidence from China

open access: yes, 2022
Emerging evidence suggests that poor mental health is particularly pronounced among Chinese residents, who are exposed to nearly the worst air pollution worldwide.

Numerical Simulation for a Three-Dimensional Air Pollution Measurement Model in a Heavy Traffic Area under the Bangkok Sky Train Platform

open access: yesAbstract and Applied Analysis, 2018
Air pollutant levels in Bangkok are generally high in street tunnels. They are particularly elevated in almost closed street tunnels such as an area under the Bangkok sky train platform with high traffic volume where dispersion is limited.

Associations of air pollutant concentrations with longitudinal kidney function changes in patients with chronic kidney disease

open access: yesScientific Reports, 2023
This longitudinal cohort study investigated the associations of air pollutant exposures, including CO, NO, NO2, NOx, O3, PM10, PM2.5, and SO2, with long-term kidney function changes in patients with chronic kidney disease (CKD).

Variability of Air Pollutant Concentrations and Their Relationships with Meteorological Parameters during COVID-19 Lockdown in Western Macedonia

open access: yes, 2023
The lockdown implemented to tackle the spread of the COVID-19 pandemic had a positive impact on air quality. Globally, studies have shown that air pollutant levels decreased temporally during the restriction measures.

Examining Personal Air Pollution Exposure, Intake, and Health Danger Zone Using Time Geography and 3D Geovisualization

open access: yesISPRS International Journal of Geo-Information, 2014
Expanding traditional time geography, this study examines personal exposure to air pollution and personal pollutant intake, and defines personal health danger zones by accounting for individual level space-time behavior.

A Remotely Controlled Calibrator for Chemical Pollutant Measuring-Units [PDF]

open access: yes, 2007
The increasing diffusion of pollutant measuring units, which are installed over wide areas, along with the short calibration interval of several sensors for pollutant quantities, requires new calibration infrastructures to be developed.

Numerical Simulation of an Air Pollution Model on Industrial Areas by Considering the Influence of Multiple Point Sources

open access: yesInternational Journal of Differential Equations, 2019
A numerical simulation on a two-dimensional atmospheric diffusion equation of an air pollution measurement model is proposed. The considered area is separated into two parts that are an industrial zone and an urban zone.
