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 ...
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 ...
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 ...
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 ...
A preliminary study on microbial air contamination in select schools in Doha, Qatar
(

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 ...
Methylmercury bioaccumulation among different food chain levels in the EEZ of Qatar (Arabian Gulf)
(
Elsevier
, 2020 , Article)
Methylmercury (MeHg) concentrations in three different species from different trophic levels with different amounts of Hg exposures were determined for the first time in the EEZ of Qatar. Sampling was conducted during ...
Physical drivers of chlorophyll and nutrients variability in the Southern-Central Arabian Gulf
(
Academic Press
