The effectiveness and usability of a diffusion tube for air quality sampling were assessed at 14 sites throughout an oil and gas production area in Atrush sub-district for measurement of Sulfur dioxide (SO2) and nitrogen dioxide (NO2) in ambient air by Palmes diffusion tubes in air during autumn and winter season of 2021-2022. Using triethanolamine as a trapping agent, the passive sampler collects SO2 and NO2, which are then proven to be sulphate and nitrite using ion chromatography and visible spectrometry. Ion chromatography was used to determine the respective dissolved ionic forms of SO2. Additionally, Ultraviolet-Visible (UV-Vis) spectrophotometry used to analyse NO2 as nitrite. Sulfur dioxide (SO2) concentration was high in locations close to flare with high elevation, as well as in winter season were higher than that of autumn season, the highest average of CPF (Central Processing Facility) is (26.39 ppb), however the highest concentration recorded is below Iraqi standard limit 140 ppb for 24 hr and lowest average at ECP3(Entry Check Point 3) (4.37 ppb) respectively. Nitrogen dioxide (NO2) concentrations were high in locations where heavy equipment’s operated and in diesel consumption areas, highest average of NO2 concentration of E pad (East Pad) is (8.94 ppb), and lowest average was in ECP3 (3.09 ppb).

“…Some adverse health effects are related to exposure of environmental pollution (Elliott et al, 2017;Elsner and Hoelzer, 2016;Paulik et al, 2016). The majority of environmental impact studies focus on water quality impacts of unconventional natural gas development (Annevelink et al, 2016;Butkovskyi et al, 2017;Jackson et al, 2015;Torres et al, 2016). However, relatively fewer studies focus on air quality impacts (Hecobian et al, 2019;Islam et al, 2016;Ren et al, 2019;Swarthout et al, 2015;Williams et al, 2018).…”

Abstract. The United States has experienced a sharp increase in unconventional natural gas (UNG) development due to the technological development of hydraulic fracturing. The objective of this study is to investigate the emissions at an active Marcellus Shale well pad at the Marcellus Shale Energy and Environment Laboratory (MSEEL) in Morgantown, West Virginia, USA. Using an ambient air monitoring laboratory, continuous sampling started in September 2015 during horizontal drilling and ended in February 2016 when wells were in production. High-resolution data were collected for the following air quality contaminants: volatile organic compounds (VOCs), ozone (O3), methane (CH4), nitrogen oxides (NO and NO2), and carbon dioxide (CO2), as well as typical meteorological parameters (wind speed and direction, temperature, relative humidity, and barometric pressure). Positive matrix factorization (PMF), a multivariate factor analysis tool, was used to identify possible sources of these pollutants (factor profiles) and determine the contribution of those sources to the air quality at the site. The results of the PMF analysis for well pad development phases indicate that there are three potential factor profiles impacting air quality at the site: natural gas, regional transport/photochemistry, and engine emissions. There is a significant contribution of pollutants during the horizontal drilling stage to the natural gas factor. The model outcomes show that there is an increasing contribution to the engine emission factor over different well pad drilling periods through production phases. Moreover, model results suggest that the regional transport/photochemistry factor is more pronounced during horizontal drilling and drillout due to limited emissions at the site.

Covalent organic frameworks are unique for their highly open architecture and attractive for use as promising gas adsorption and storage carriers. In this work, density functional theory calculations have been performed to investigate the properties of metal-doped covalent organic frameworks and their interactions with the SO2 gas molecule. It is found that a single metal atom (including Li, Na, K, and Sc) doped at the top of phenyls within the tetra(4-dihydroxyborylphenyl) silane (TBPS) building block of covalent organic frameworks can easily lose its valence electrons and can be positively charged. The SO2 gas molecule could be stably absorbed onto the metal-doped covalent organic frameworks. The absorbed SO2 molecule interacts with Li, Na, K, and Sc metal-doped covalent organic frameworks by the dominant donor-acceptor delocalization between 1-center lone pair of an oxygen atom within SO2 and 1-center non-Lewis lone pairs of the doped metal atom.
