Book Description
in this book there are some methods to extraction of polycyclic aromatic hydrocarbons(with some modified) from many environmental medium, measured it and measured the physical and chemical properties for these medium and study the phytoplanktons and analyzed by statistical process. finally explain the using of some phytoplanktons as bioindicators, biosensors and biomonitors. this book very benefit for any searchers in polycyclic aromatic hydrocarbons, phytoplanktons and physical and chemical properties for water, sediments and organisms.

Book Description
This book deals with the sources, distribution, analytical methods, and monitoring of Polycyclic aromatic hydrocarbons (PAH) in the occupational environment. It is hoped that this book will make a contribution to understanding the formation and determination of PAH in work atmosphere and that it will make a particular contribution to occupational health projects. Much of the information given in this book has been generating in studies carried out in cooperation with the Norwegian aluminium industry.

Book Description
The volumes 3/I and 3/J present a modern account of polycyclic aromatic hydrocarbons (PAHs) and their heterocyclic analogs in the environment. The authors are internationally well recognized scientists belonging to those working presently in the frontline of the different subfields of this interdisciplinary area of environmental science; they give an integrated thorough overview on this hot topic. Extensive cross-referencing between chapters provides the readers with an easy access to all major areas. Due to the huge amount of material the text is published in two volumes (3/I and 3/J). It is expected that both volumes will soon become a major source of information and inspiration for all researchers actively working in PAH environmental chemistry or ecology.

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
The present survey comprises today‘s knowledge of environmental pollution in particular of the atmosphere by PAH and of the biological effects of this class of substance, putting special emphasis on their carcinogenic activity. The research data and conclusions derived therefrom are meant to assist the government of the Federal Republic of Germany in determining an air quality standard.
