Baseline concentrations and distributions of Polycyclic Aromatic Hydrocarbons in surface sediments from the Qatar marine environment
( Elsevier , 2017 , Article)Coastal sediments in marine waters of Qatar have the potential of being contaminated by Polycyclic Aromatic Hydrocarbons (PAHs) due to extensive petroleum exploration and transportation activities within Qatar's ... -
Elemental compositions of particulate matter retained on air condition unit’s filters at Greater Doha, Qatar
( Springer Netherlands , 2019 , Article)© 2019, The Author(s). Elemental composition of airborne dust samples retained by internal filters of air condition units (ACUs) was determined at 12 locations of Doha city, state of Qatar. Twenty-four elements: Al, Ca, ... -
Geochemical composition of Aeolian dust and surface deposits from the Qatar Peninsula
( Elsevier , 2018 , Article)Abstract The trace metal geochemistry of atmospheric dust and terrestrial surface particles were studied on the Qatar Peninsula from February 2014 to November 2015. We included samples of the mega dust-storm event on 01–02 ... -
Geochemical composition of dust from Qatar peninsula
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Conference paper)Atmospheric dust samples have been collected from different areas in Qatar and analyzed for major and trace element composition. This region of the Arabian Gulf represents an area largely affected by dust from natural and ... -
Mercury accumulation in Lethrinus nebulosus from the marine waters of the Qatar EEZ
( Elsevier , 2017 , Article)Total mercury (THg) and methylmercury (MeHg) were recorded in the commercial demersal fish Lethrinus nebulosus, caught from six locations in Qatar EEZ (Exclusive Economic Zone). Concentrations of THg decreased in the ... -
Observed variability in physical and biogeochemical parameters in the central Arabian Gulf
( ELSEVIER , 2021 , Article)In situ measurements of physical and biogeochemical variables were conducted along a transect in the Exclusive Economic Zone (EEZ) of Qatar during late summer (September 2014) and winter (January 2015) to investigate their ... -
Ocean Acidification and Carbonate System Geochemistry in the Arabian Gulf
( Qatar University Press , 2020 , Poster)Alkalinity (Alk) and (Dissolved Inorganic Carbon) DIC were measured on high resolution seawater samples, collected on November 2018 and May 2019 at seven stations in the Exclusive Economic Zone (EEZ) of Qatar. Calculated ... -
Polycyclic aromatic hydrocarbons in dust from the indoor environment of Qatar
( Hamad Bin Khalifa University Press , 2016 , Conference Paper)Polyaromatic Hydrocarbons (PAHs) concentrations in dust trapped on air conditioning unit filters operating in residential and workplace locations in Doha, Qatar were sampled and measured. Fourteen samples were collected ... -
A preliminary study on microbial air contamination in select schools in Doha, Qatar
( Springer Nature , 2021 , Article)Available data of the indoor airborne culturable bacteria and fungi at schools’ environments is very limited in the peninsula of Qatar. This study aims to determine the microbial load in indoor and outdoor air at three ... -
Radioactivity levels in the marine environment along the Exclusive Economic Zone (EEZ) of Qatar
( Elsevier , 2015 , Article)A study on 137Cs, 40K, 226Ra, 228Ra, and 238U was carried out along the EEZ of Qatar. Results serve as the first ever baseline data. The level of 137Cs (mean value 1.6 ± 0.4 Bq m 3) in water filters was found to be in the ... -
Spatial variability of summer hydrography in the central Arabian Gulf
( Elsevier , 2021 , Article)The Arabian Gulf is a very significant ocean body, which hosts more than 55% of the oil reserves of the world and produces about 30% of the total production, and thus, it is likely to face high risk and adverse problems ... -
Target gastropods for standardizing the monitoring of tar mat contamination in the Arabian Gulf
( Elsevier , 2022 , Article)This study proposes a standardization process for the monitoring the level of tar mat contamination in the Arabian Gulf. In the study, we selected target gastropod species and evaluated the ecological and ecotoxicological ... -
The Influence of Qatari Dust on the Element Composition of Marine Plankton
( Qatar University Press , 2021 , Poster)The Exclusive Economic Zone (EEZ) of Qatar is affected by extreme dust and extensive industrialization, making it an ideal location to examine influences of coastal processes on biological activity, which greatly affects ... -
Trace element composition of size-fractionated suspended particulate matter samples from the Qatari Exclusive Economic Zone of the Arabian Gulf: the role of atmospheric dust
( Copernicus Publications , 2020 , Article)We analyzed net-tow samples of natural assemblages of plankton, and associated particulate matter, from the Exclusive Economic Zone (EEZ) of Qatar in the Arabian Gulf. Size-fractionated suspended particles were ... -
Variability of Physical and Biogeochemical Parameters in the Exclusive Economic Zone of Qatar
( Qatar University Press , 2021 , Poster)The oceanographic data collected along a transect in the Exclusive Economic Zone (EEZ) of Qatar during late summer (September 2014) and winter (January 2015) have been analyzed to investigate the spatial and temporal ...
