Prevalence of microplastics in the marine waters of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)The issue of plastic pollution in the marine environment is of increasing global concern. As plastics typically have an intrinsic durability, water insolubility and slow degradation rates, debris has now become both ... -
Prevalence of microplastics in the marine waters of Qatar
( Elsevier Ltd , 2016 , Article)Microplastics are firmly recognized as a ubiquitous and growing threat to marine biota and their associated marine habitats worldwide. The evidence of the prevalence of microplastics was documented for the first time in ... -
Probabilistic human health risk assessment of trace elements in ballast water treated by reverse osmosis desalination plants
( Elsevier , 2023 , Article)Very few studies have paid attention to the transport of heavy and toxic metals via ballast water coming from different countries of the world. In the present study, ballast water samples (n = 83) were collected from ships, ... -
Prospects for climate-scale regional numerical modelling for the Arabian Gulf and Qatar's marine region
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Physical oceanographic studies at the Environmental Science Center (ESC) entail observational and numerical aspects.

Qatar’s vision of global problems, challenges and solutions
( QScience - Hamad Bin Khalifa University Press , 2016 , Conference Paper)Since Qatar first signed the Biodiversity Convention in Rio in 1992, Qatar has been a strong advocate with keen interest in sustainability and the preservation of its biodiversity noting that advancement in industry should ... -
Quantification of ecosystem services providing socio-economic benefits to customary owners of natural resources in Pauri, western Himalaya
( Elsevier , 2022 , Article)Climate change has negative consequences for the biophysical environment and an observable impact on flows of ecosystem services. Considering the high relevance of ecosystem services, it is imperative to analyze the present ... -
Quantifying variations in ecosystem services in altitude-associated vegetation types in a tropical region of China
( Elsevier , 2020 , Article)Natural vegetation is important for ecosystem services (ESs) provision, but is decreasing rapidly due to human-driven land use change, especially rapid expansion of commercial plantations. This is leading to a decrease in ... -
A quantity-distribution synthesized framework for risk assessment of algal blooms
( Elsevier , 2023 , Article)Algal blooms threaten water safety and quality, particularly in lakes with vulnerable environment and advanced urbanization. Due to low water exchange rate and multiple human activity influences, algal blooms in inland ... -
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 ... -
Raman Spectroscopic and Microbial Study of Biofilms Hosted Gypsum Deposits in the Hypersaline Wetlands: Astrobiological Perspective
( Mary Ann Liebert Inc. , 2023 , Article)Gypsum (CaSO4.2H2O) has been identified at the surface of Mars, by both orbiters and rovers. Because gypsum mostly forms in the presence of liquid water as an essential element for sustaining microbial life and has a low ... -
