“…Finally, Hagan et al (2011) have made an estimation of historical mercury concentrations in the atmosphere of Potosí, on the basic of historic production data, and analyzed mercury concentrations in the local soils, finding values between 0.105 and 155 mg kg − 1 ; an important conclusion expressed in the Hagan et al (2011) paper is the need for studies correlating the present day soil Hg concentrations with atmospheric Hg concentrations, which is precisely the main goal of our study.…”

“…Natural atmospheric Hg emissions from volcanoes, crustal weathering and hydrothermal activity are thought to be 1-2 orders of magnitude smaller than modern anthropogenic Hg emissions (Amos et al, 2015;Bagnato et al, 2014;UNEP, 2013). Prior to the 1850s, anthropogenic Hg releases mainly came from primary Hg mining and use of Hg as amalgamation agent for silver extraction in the Spanish colonial Americas (Camargo, 2002;Hagan et al, 2011;Robins and Hagan, 2012). Following the industrial revolution, anthropogenic Hg releases further increased due to large-scale gold mining, non-ferrous metal production and combustion of fossil fuels (Streets et al, 2011).…”

Mercury (Hg) stable isotopes provide a new tool to trace the biogeochemical cycle of Hg. An inventory of the isotopic composition of historical anthropogenic Hg emissions is important to understand sources and post-emission transformations of Hg. We build on existing global inventories of anthropogenic Hg emissions to the atmosphere to develop the first corresponding historical Hg isotope inventories for total Hg (THg) and three Hg species: gaseous elemental Hg (GEM), gaseous oxidized Hg (GOM) and particulate-bound Hg (PBM). We compile d

“…AERMOD makes distribution calculations by using the meteorological characteristics of the study area, including data such as chimney height and diameter, emission temperature, pollutant exit velocity and air temperature turbulence, and wind speed and direction, and can be used in rural and urban areas, plain and complex terrains, and in multiple sources such as point, line, area, and volume [8][9][10][11][12][13][14][15][16][17][18]. The AERMOD program needs hourly surface and upper air layer data in order to be able to make these calculations [9].…”

“…Distribution models can calculate the air pollution concentrations by using emission, meteorological, and topographical data. Although time requirements and data entries are difficult for the calculations, successful estimations can be made in regards to distributions [7][8][9]. Atmospheric distribution is a complex process that varies depending on topography, meteorology, emissions, and land use.…”

Air quality modellings are highly useful systems used to investigate the possible impact of emissions diffusing into the atmosphere in any area they might have on that area. There are many modelling methods whose capacities are limited by their advantages and disadvantages or the equipment they use. In this study, therefore, both steady-state models (AERMOD and ISCST-3) and the Lagrangian model (CALPUFF) are used. This study has two purposes: one is to specify performance of the models. Performances were determined with various statistical methods such as fractional bias (FB), mean squared error (MSE), and geometric mean bias (MG). The other purpose of this study is to evaluate temporal and spatial variations of point (P), area (A), and line (L) -sourced CO and NO x emissions in the research area by using the modelling methods. The district of Körfez, which is one of the districts of the province of Kocaeli, was chosen as the study area.When the results obtained with modelling all P and A sources by three programs are analyzed, the highest annual concentration AERMOD, ISCST-3, and CALPUFF were found as 128.82, 86.96, and 201.30 µg/m 3 for CO, and 7.56, 26.31, and 6.10 µg/m 3 for NO x , respectively. On the other hand, when the results obtained with modelling all P and A and L sources by two programs are investigated, the highest annual concentration AERMOD and ISCST-3 were found to be 155.12, 92.46 µg/m 3 for CO, and 166.93 and 89.98 µg/m 3 for NO x , respectively. When contributions of the pollutant sources on pollution are evaluated, it was observed that area sources and line sources are more predominant than other sources for CO and NO x emissions. It was observed by analyzing the diffusion maps that residential areas in the district are more concentrated. Therefore, in the study the predicted and observed values were also compared with national and international limit values and determined to meet these limit values. According to the results obtained by evaluation of performances of the models with FB, MS, and MG statistical methods, performance sorting for NO x emissions was found to be ISCST-3 > CALPUFF > AERMOD, while for CO emissions it is given as
