Elevated stacks’ pollutants’ dispersion and its contributions to photochemical smog formation in a heavily industrialized area

Abstract

In this study, the photochemical smog formation over a heavily industrialized area with complex terrain was investigated. A mesoscale prognostic meteorological and air pollution model was used in combination with data, which were collected by in situ and remote monitoring stations. The area of interest is a mountainous basin in north-western Greece. The intensive industrial activity in this area has resulted in effects on the air quality of the area, mainly caused by the lignite-fired power stations and the lignite mining operation. The study focused on the dispersion of ozone production due to primary pollutants' emissions from the power stations (PSs). Moreover, the investigation of this external sources' contribution to the ozone concentrations measured in Kozani, the most populated city of the area, is ventured. The results showed a considerable skill of the model in predicting the major mesoscale features affecting the pollutants' dispersion and concentrations in the area of interest. Numerical simulation data of photochemical pollutants were significantly correlated with meteorology during the simulation period. The correlation reveals the most important factors of ozone production, such as solar radiation, temperature, wind speed and topography. The obtained results have contributed to the verification of distant pollutants' transfer from industrial sources.

The Effect of Meteorological Elements on Continuing Heavy Air Pollution: A Case Study in the Chengdu Area during the 2014 Spring Festival

“…There was a positive correlation between the concentration of SO 2 and NO 2 and the daily duration of sunshine. Many studies also suggest that increased air pollutant concentrations in the urban environment do not typically result from sudden increases in emission, but rather from meteorological conditions that impede dispersion in the atmosphere or result in increased pollutant generation [7,[38][39][40]. Shen and Li (2016) showed that the coefficients between API and an atmospheric pressure anomaly, and precipitation and wind speed, are always negative at the studied time scales [10].…”

“…In particular, meteorological conditions control the occurrence of haze pollution [3,[7][8][9][10][11][12][13][14][15][16][17][18][19]. In China, most studies are focused on the Jingjinji area (Beijing), the Yangtza river delta (Shanghai), and the Pearl River delta (Guangzhou, Zhujiang).…”

Performance and evaluation of a coupled prognostic model TAPM over a mountainous complex terrain industrial area

“…This paper focuses on the evaluation of the performance of the air pollution model (TAPM) in the region of Western Macedonia, Greece. Despite some attempts to evaluate TAPM in a mountainous terrain (Triantafyllou et al 2011;Aidaoui et al 2014;Matthaios et al 2016), from the current bibliography and as far as the authors are aware, this is the first detailed and long-term attempt to evaluate TAPM in a mountainous complex terrain area. However, there have been several studies concerning the model's performance in a coastal and/or flat terrain.…”

Development of High‐Voltage Aqueous Electrochemical Energy Storage Devices

“…With the continuous consumption of oil resources and increasing environmental problems, it has become a global urgency to push the exploration of renewable energy sources such as the wind and solar energy. The key is to develop an efficient, low‐cost, and environmentally friendly energy storage device .…”
