“…This study selected the “puffs” method to represent pollutant emissions. The calculation of turbulent transport relied on the Pasquill–Gifford–Turner coefficient method for rural areas and the McElroy-Pooler coefficient for urban areas [ 47 , 48 ], which is the default option. No chemical reactions or deposition were considered.…”

“…The base of this study is an air quality analysis for the Warsaw agglomeration from the year 2012, presented in [ 5 , 12 ]. To simulate pollution dispersion processes, the Gaussian puff model CALPUFF v.5, [ 13 ], frequently applied in regional/urban scale analysis of air quality [ 12 , 14 ] and recommended by US EPA [ 15 ], was used. It is a multilayer, non-stationary model designed for calculating concentrations of many substances, emitted by different types of sources.…”

Air pollution is a significant public health issue all over the world, especially in urban areas where a large number of inhabitants are affected. In this study, we quantify the health burden due to local air pollution for Warsaw, Poland. The health impact of the main air pollutants, PM, NOX, SO2, CO, C6H6, BaP and heavy metals is considered. The annual mean concentrations are predicted with the CALPUFF air quality modeling system using the year 2012 emission and meteorological data. The emission field comprises point, mobile and area sources. The exposure to these pollutants was estimated using population data with a spatial resolution of 0.5 × 0.5 km2. Changes in mortality and in disability-adjusted life-years (DALYs) were estimated with relative risk functions obtained from literature. It has been predicted that local emissions cause approximately 1600 attributable deaths and 29,000 DALYs per year. About 80% of the health burden was due to exposure to fine particulate matter (PM2.5). Mobile and area sources contributed 46% and 52% of total DALYs, respectively. When the inflow from outside was included, the burden nearly doubled to 51,000 DALYs. These results indicate that local decisions can potentially reduce associated negative health effects, but a national-level policy is required for reducing the strong environmental impact of PM emissions.

“…CALPUFF View is a multi-layer, multi-species, non-steady-state puff dispersion model that simulates the effects of time and space with varying meteorological conditions on pollution transport, transformation, and removal. This model uses a Gaussian equation to characterize the atmospheric processes that disperse a pollutant emitted by a source, based on emissions and meteorological inputs [29][30][31][32]. The concept of this model can be summarized as shown in Figure 2.…”

Atmospheric Dispersion of Gaseous Amine Emitted from Absorption-Based Carbon Capture Plants in Saskatchewan, Canada

et al. 2022

Carbon capture and storage (CCS) is a key strategy to reduce carbon dioxide (CO2) emissions from industrial point sources. Gas absorption into aqueous amine solutions is an immediate technology for carbon capture that has been tested in many demonstration plants. One concern of using the amine-based carbon capture process is the environmental impacts and health risk caused by emissions of gaseous amines from the process to the atmosphere. This work applied the knowledge of air dispersion modelling to map out the atmospheric dispersion and resulting ground surface level concentration of gaseous amine, namely Monoethanolamine (MEA), from a coal-fired power plant (with a carbon capture unit) and in surrounding areas, in case of an accidental leaking of amine from the CCS system to the atmosphere. The chosen study area was centered on a coal-fired power plant in the province of Saskatchewan, Canada. The Environmental Protection (EPA) approved air pollution model (CALPUFF), together with meteorological and geophysical data were used for gaseous amine dispersion simulation. The results were presented, and the ground amine concentrations were found to vary with wind patterns (wind direction and wind speed). The maximum ground surface amine concentrations standard is 15.2 µg/m3. However, the results showed that when using the water wash unit, the MEA concentrations were well below the standard level, compared to those without the water wash unit. It is essential for CO2 capture plants located in highly populated areas to be equipped with water wash units.
