Accumulation of Trace Metals, Petroleum Hydrocarbons, and Polycyclic Aromatic Hydrocarbons in Marine Copepods from the Arabian Gulf

Accumulation of trace metals, petroleum hydrocarbons, and polycyclic aromatic hydrocarbons in marine copepods from the Arabian Gulf.

Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils

Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...

Heavy Metals, Trace Elements and Petroleum Hydrocarbons Pollutions in the Arabian Gulf: Review

The Arabian Gulf environmental status was assessed based on studies conducted in Bahrain, Kuwait, Oman, Saudi Arabia, Qatar, United Arab Emirates (UAE), and Yemen during 1983-2011. This review examines all sorts of pollutions in the Arabian Gulf area over the last three decades. Approximately 50 published studies were reviewed in order to determine the pollution status in the Arabian Gulf regar...

Dietary exposure to polycyclic aromatic hydrocarbons from commercially important seafood of the Arabian Gulf

In order to assess the dietary intake of polycyclic aromatic hydrocarbons (PAHs) by Kuwaiti population, concentrations of PAHs were determined in edible tissues of commercially important seafood (fish and shrimp) samples collected from fish markets in 2005. Naphthalene, phenanthrene, fluoranthrene, pyrene, benz[a]anthracene and chrysene were routinely detected in all samples analyzed. The conce...

Determination of petroleum hydrocarbons and polycyclic aromatic hydrocarbons in sludge from wastewater treatment basins.

Screening by gas chromatography with flame ionization detection and gas chromatography-mass spectrometry has been carried out on sludge extracts of wastewater treatment basins. Soxhlet extraction with trichlorotrifluoroethane was applied. The yields for petroleum hydrocarbons and PAH recovery were high, usually in excess of 90%. The proposed investigations permit a quick assessment of petroleum...
