Natural bitumen and extra-heavy oil Natural bitumen and extra-heavy oil
Since 2005, oil price increases have greatly increased investment in the production of extra- heavy oil and natural bitumen (tar sands or oil sands) to supplement conventional oil supplies. These oils are characterised by their high viscosity, high density (low API gravity), and high concentrations of nitrogen, oxygen, sulphur, and heavy metals. Extra-heavy oil and natural bitumen are...

Towards quantitative monitoring of semivolatile organic compounds using passive air samplers: Chapter 6 Towards quantitative monitoring of semivolatile organic compounds using passive air samplers: Chapter 6
Passive air samplers can be used to measure the air concentration of various semivolatile organic compounds (SOCs) with reasonable reliability. To use passive air samplers to measure atmospheric concentrations of pollutants, calibration data are required. Calibration data include parameters such as sampling rates, sampler/air partition coefficients and loss rate constants. These...

Nowcasting recreational water quality Nowcasting recreational water quality
Advances in molecular techniques may soon provide new opportunities to provide more timely information on whether recreational beaches are free from fecal contamination. However, an alternative approach is the use of predictive models. This chapter presents a summary of these developing efforts. First, we describe documented physical, chemical, and biological factors that have been...

Chapter 7 Magmatic-hydrothermal fluid interaction and mineralization in alkali-syenite nodules from the Breccia Museo pyroclastic deposit, Naples, Italy Chapter 7 Magmatic-hydrothermal fluid interaction and mineralization in alkali-syenite nodules from the Breccia Museo pyroclastic deposit, Naples, Italy
The Breccia Museo, a pyroclastic flow that crops out in the Campi Flegrei volcanic complex (Naples, Italy), contains alkali-syenite (trachyte) nodules with enrichment in Cl and incompatible elements (e.g., U, Zr, Th, and rare-earth elements). Zircon was dated at ≈52 ka, by U-Th isotope systematics using a SHRIMP. Scanning electron microscope and electron microprobe analysis of the...
