Monitoring Polycyclic Aromatic Hydrocarbon Pah Bioavailability Near Offshore Produced Water Discharges

Monitoring Polycyclic Aromatic Hydrocarbon (PAH) Bioavailability Near Offshore Produced Water Discharges

Produced water is the largest volume waste associated with production of oil and gas on offshore platforms. Produced water that meets effluent limitations for total oil and grease contains low concentrations of petroleum hydrocarbons, low molecular weight organic acids, and several metals. The U.S. EPA has expressed concern that some of these chemicals could be bioaccumulated to potentially toxic concentrations by marine organisms in the receiving waters of offshore produced water discharges. This paper presents the results of an intensive monitoring study to determine if marine animals bioaccumulate polycyclic aromatic hydrocarbons (PAHs) from produced water discharges to offshore waters of the Gulf of Mexico.

Petrogenic Polycyclic Aromatic Hydrocarbons in the Aquatic Environment: Analysis, Synthesis, Toxicity and Environmental Impact

Although a lot is known about the influence of Polycyclic Aromatic Hydrocarbons (PAHs) on the marine environment, there are still many unanswered questions. Petrogenic Polycyclic Aromatic Hydrocarbons in the Aquatic Environment is a monograph that sums up basic knowledge about this topic while highlighting current research practices useful in studying the aquatic environment. It starts with an introduction to effect of PAH in the marine environment. It then proceeds to provide information on techniques to monitor PAH levels and investigate the affected environment in order to control the subsequent negative effects. Chapters also detail the carcinogenic and endocrine effects of PAHs on fish as well as the degradation of PAHs by microorganisms. This monograph is a useful reference for environmental science students and professionals learning about the role of PAH in the marine environment.
