Book Description
Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.

Book Description
The Deepwater Horizon (DWH) oil spill occurred April 20, 2010 to July 15, 2010, releasing a surface slick of crude oil extending to ~176,000 km2 in the Gulf of Mexico (GOM). Crude oil is comprised of thousands of organic compounds, many of which are toxic or carcinogenic. There is concern that some petroleum-derived toxic and carcinogenic hydrocarbons from the DWH spill may have volatilized and transported landward to the Gulf Coast States. It is important to determine the fate of these oil-derived compounds since their landward transport and inhalation may compromise human health. Polycyclic aromatic hydrocarbons (PAHs) are one suite of organic compounds that have been used to fingerprint oil to identify its source. In this study, the relative abundance of 34 PAHs derived from the DWH spill were compared to those found in oil from natural seeps in the northern GOM and from various sources in the Santa Barbara Channel, CA. The PAH distributions of the DWH oil were also compared to PAH distributions in air and water samples collected from several coastal sites in the Gulf Coast States sampled in July, 2010 and July, 2011. Additionally, the distributions of PAHs in air and water samples were compared before and after passage of Tropical Storm (TS) Bonnie (2010) that traveled across the GOM in late July, 2010. Lastly, particulate organic carbon and black carbon (a combustion byproduct) were extracted from these air samples to provide more information on the sources of air masses in the region. The results from this study suggest that the DWH riser oil contained ~3,600 [mu]g g−1 of total PAHs and an average ~500 [mu]g g−1 of PAHs in the surface slick. Ambient level of PAHs in air and water collected from coastal areas of the GOM were similar between 2010 and 2011, despite the presence of the oil slick from the DWH spill. However, our results indicate that the marine-to-land transport vector was facilitated by passage of TS Bonnie across the DWH oil slick in July, 2010. For example, the total atmospheric PAH loading to window film (a passive air sampler) increased by a factor-of-fifty after the passage of the storm, and the TS Bonnie rainwater contained dissolved organic carbon with a 14C age of ~8,000 y BP. Together, these results suggest that marine-to-land atmospheric loading of organic carbon and contaminants may be important during tropical storms and hurricanes.

Book Description
This book describes the sources of water contamination by PAHs and their transportation and fate in natural aquatic systems. It then discusses, from the analytical chemist’s view, how to determine the presence of PAHs in water and wastewater, and the changes in PAH concentration during treatment processes. The text examines the removal of PAHs using membrane bioreactors and advanced sludge processes, highlighting results from both demonstration and full-scale plants. It also examines the presence of PAHs in conventional wastewater treatment plants, especially in sludge.

Book Description
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.

Book Description
On April 20, 2010, BP's Deepwater Horizon oil rig exploded leaking over 200 million gallons of crude oil into the Gulf of Mexico for 84 days. Exposure to oil-associated polycyclic aromatic hydrocarbons (PAHs) in the water and sediment could severely impact the aquatic organisms inhabiting the Gulf of Mexico (i.e. developmental defects, reproductive effects, death, etc.). Therefore, water, sediment and oyster, Crassostrea virginica, samples were collected approximately bimonthly between May 26 and November 30, 2010 from multiple sites along the Gulf Coast, namely, two sites in Mobile Bay (Denton and Sand Reefs at 1 or 0.1 m above the bay floor), one site near Orange Beach, AL (Perdido), and one near Pointe aux Pines, MS. Water, sediment, and oysters were extracted for quantitation of 24 PAHs by gas chromatography mass spectrometry (GC/MS). The concentration range for total PAHs (tPAH) in water was non-detectable to 1100 ng/L and non-detectable to 7450 ng/g for sediment. The highest water tPAH concentrations were observed on 6/28/10 for Sand (1 m), 7/21/10 for Denton (0.1 m), 9/9/10 for Perdido, and 9/22/10 for Pointe aux Pines. The highest sediment concentrations were observed on 9/20/10 for Denton Reef, 7/7/10 for Sand Reef, 7/28/10 for Perdido, and 9/22/10 for Pointe aux Pines. Twenty other sites along the northern Gulf coast collected less frequently also indicated relatively low (
