Oyster habitats in the United Arab Emirates are highly diverse marine ecosystems with fascinating historical cultural and fisheries importance for pearls, but also for provisioning local people with food and materials for direct consumption and income. Their hard structure protects coastal areas and human populations and their assets, while their s...

This study presents a comprehensive data analysis using univariate and multivariate statistical techniques as a tool to establish a baseline for the assessment of water quality parameters in environmental compartments. The Al Wasit Nature Reserve is a hypersaline wetland in the UAE with a spatial fluctuation in water parameters as water flows above...

Coconut Creek (Florida), ISSN 0749-0208. This geobotanical study describes the United Arab Emirates (UAE) mangrove and coastal halophyte plant communities in the intert...

Microplastics pollution in oyster bed ecosystems was investigated in this study. Microplastics in both sediments and oysters from five sites collected along the coast of the United Arab Emirates (UAE) oyster bed ecosystem were assessed for abundance, as well as shape, size, color, and composition. The mean abundance in the sediment samples was 191....

The objectives of this research were: (1) To examine the outcomes and key factors of success (KFS) related to ISO 14001 certification, (2) to compare and contrast these in private organizations (PRIVOs) and public organizations (PUBOs), and (3) in the under-explored context of an Arab Gulf country with an emerging economy: The United Arab Emirates....

Worldwide, ISO 14001 certification for organizations has become the norm, but the Arab world accounts for an insignificant portion of all the certified organizations. There is a dearth of research on environmental management systems (EMS) in Arab and emerging countries and in public organizations. The objectives of this research are to: (1) examine...

This editorial introduces the issue of selected papers that were presented at the third International Conference on Environmental Pollution, Restoration, and Management in Quy Nhon, Vietnam on 6-10 March 2017. While environmental problems caused by diverse municipal, industrial, and other economic development activities continue to increase in many...

Domestic waste contamination has adverse health effects and detrimental ecological impact. This paper presents the results of an investigation of domestic waste contamination; specifically fecal contamination of ground and surface water in Al Wasit Nature Reserve in Sharjah, United Arab Emirates (UAE). This reserve, which comprises a broad hyper-sa...

Wadi Wurayah, in the Emirate of Fujairah, United Arab Emirates, lies within the Hajar Mountain range by the Gulf of Oman. The climate of the area is influenced by climatic events originating in Africa, Eastern Europe-Siberia, and the Indian and Pacific oceans. Rainfall provides 18.7 hm water annually, with an average of 2.24 hm as runoff. Recharge...

Adult male deer mice were exposed every other day for a period of 11 days to either 7,12-dimethylbenzanthracene (DMBA; CAS# 57-97-6) or benzo[b]fluoranthene (BbF; CAS# 205-99-2) (0, 0.3, 1, 3, 10, or 30 mg kg). Immune endpoints assessed were lymphocyte proliferation, macrophage pinocytosis, and the antibody plaque-forming cell (PFC) response. Cytoc...

Polycyclic aromatic hydrocarbons (PAHs) are among the most common classes of chemical contaminants found at hazardous waste sites. Deer mice (Peromyscus maniculatus) exhibit a wide geographic distribution throughout North America and have been suggested as a terrestrial biomonitoring species to facilitate comparisons between superfund sites. Chemic...

Improper pesticide management can lead to environmental problems such as water quality degradation and ecological stress. Recent research in our laboratory has focused on development of constructed wetlands to assimilate pesticide-contaminated water. For improved aesthetics, these wetlands have been established with ornamental plant species. The ef...

The evaluation of the phytotoxicity of a chemical is an essential component of the ecological risk assessment of that compound. Primary producers form an essential trophic level of any ecosystem. Further, since all chemicals introduced into the environment ultimately find their way into aquatic ecosystems, aquatic algal and plant toxicity evaluatio...
