The term “total petroleum hydrocarbons” (TPHs) is used for any mixture of several hundred hydrocarbons found in crude oil, and they represent the sum of volatile petroleum hydrocarbons and extractable petroleum hydrocarbons. The petrol-range organics include hydrocarbons from C6 to C10, while diesel-range organics are C10-C28 hydrocarbons. Environmental pollution by petroleum hydrocarbons is one of the major global concerns, particularly in oil-yielding countries. In fact, there are more than five million potentially contaminated areas worldwide that represent, in general, a lost economic opportunity and a threat to the health and well-being of humans and the environment. Petroleum-contaminated sites constitute almost one-third of the total sites polluted with chemicals around the globe. The land contamination caused by industrialization was recognized as early as the 1960s, but less than a tenth of potentially contaminated lands have been remediated due to the nature of the contamination, cost, technical impracticability, and insufficient land legislation and enforcement. This book is the first single source that provides comprehensive information on the different aspects of TPHs, such as sources and range of products, methods of analysis, fate and bioavailability, ecological implications including impact on human health, potential approaches for bioremediation such as risk-based remediation, and regulatory assessment procedures for TPH-contaminated sites. As such, it is a valuable resource for researchers, graduate students, technicians in the oil industry and remediation practitioners, as well as policy makers.
This book takes readers back and forth through time and makes the past accessible to all families, students and the general reader and is an unprecedented collection of a list of events in chronological order and a wealth of informative knowledge about the rise and fall of empires, major scientific breakthroughs, groundbreaking inventions, and monumental moments about everything that has ever happened.
JACK LONDON (1876-1916), American novelist, born in San Francisco, the son of an itinerant astrologer and a spiritualist mother. He grew up in poverty, scratching a living in various legal and illegal ways -robbing the oyster beds, working in a canning factory and a jute mill, serving aged 17 as a common sailor, and taking part in the Klondike gold rush of 1897. This various experience provided the material for his works, and made him a socialist. "The son of the Wolf" (1900), the first of his collections of tales, is based upon life in the Far North, as is the book that brought him recognition, "The Call of the Wild" (1903), which tells the story of the dog Buck, who, after his master ́s death, is lured back to the primitive world to lead a wolf pack. Many other tales of struggle, travel, and adventure followed, including "The Sea-Wolf" (1904), "White Fang" (1906), "South Sea Tales" (1911), and "Jerry of the South Seas" (1917). One of London ́s most interesting novels is the semi-autobiographical "Martin Eden" (1909). He also wrote socialist treatises, autobiographical essays, and a good deal of journalism.
