Total Petroleum Hydrocarbons

Total Petroleum Hydrocarbons PDF Author: Saranya Kuppusamy
Publisher: Springer
ISBN: 3030240355
Category : Science
Languages : en
Pages : 278

Book Description
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.

Managing Arsenic in the Environment

Managing Arsenic in the Environment PDF Author: Ravi Naidu
Publisher: CSIRO PUBLISHING
ISBN: 0643099239
Category : Technology & Engineering
Languages : en
Pages : 656

Book Description
Arsenic is one of the most toxic and carcinogenic elements in the environment. This book brings together the current knowledge on arsenic contamination worldwide, reviewing the field, highlighting common themes and pointing to key areas needing future research. Contributions discuss methods for accurate identification and quantification of individual arsenic species in a range of environmental and biological matrices and give an overview of the environmental chemistry of arsenic. Next, chapters deal with the dynamics of arsenic in groundwater and aspects of arsenic in soils and plants, including plant uptake studies, effects on crop quality and yield, and the corresponding food chain and human health issues associated with these exposure pathways. These concerns are coupled with the challenge to develop efficient, cost effective risk management and remediation strategies: recent technological advances are described and assessed, including the use of adsorbants, photo-oxidation, bioremediation and electrokinetic remediation. The book concludes with eleven detailed regional perspectives of the extent and severity of arsenic contamination from around the world. It will be invaluable for arsenic researchers as well as environmental scientists and environmental chemists, toxicologists, medical scientists, and statutory authorities seeking an in-depth view of the issues surrounding this toxin.

Permeable Reactive Barrier

Permeable Reactive Barrier PDF Author: Ravi Naidu
Publisher:
ISBN:
Category : Groundwater
Languages : en
Pages : 0

Book Description
Remediation of ground water is complex and often challenging. The passive remediation technology, currently in vogue, is based on permeable reactive barriers (PRB) that allow water to pass through while the fence/barrier made of reactive materials remediates the contaminants. Although PRB has been in operation for over a decade there are limited published books available. This book covers in one single volume all the information needed to plan, design/model and apply a successful, cost-effective and sustainable PRB technology.
