Investigating the fate of petroleum fluids released in the marine environment with comprehensive two-dimensional gas chromatography and transport models

Anthropogenic releases of petroleum fluids, which contain thousands of compounds, represent a threat to marine environments. However, there was a lack of models able to explain the independent behaviors of the numerous compounds of a spilled petroleum flui ...

Simulating gas-liquid-water partitioning and fluid properties of petroleum under pressure: Implications for deep-sea blowouts

Jeremy Samuel Arey, Jonas Gros

With the expansion of offshore petroleum extraction, validated models are needed to simulate the behaviors of petroleum compounds released in deep (>100 m) waters. We present a thermodynamic model of the densities, viscosities, and gas-liquid-water partiti ...

GCxGC Quantification of Priority and Emerging Nonpolar Halogenated Micropollutants in All Types of Wastewater Matrices: Analysis Methodology, Chemical Occurrence, and Partitioning

Jeremy Samuel Arey, Jonas Gros, Juliane Hollender, Saer Samanipour, Petros Dimitriou Christidis, Alex Bonvin, Rebecca Rutler, Jimmy Westphale

We report the development and validation of a method to detect and quantify diverse nonpolar halogenated micropollutants in wastewater treatment plant (WWTP) influent, effluent, primary sludge, and secondary sludge matrices (including both the liquid and p ...

Analyte quantification with Comprehensive Two-Dimensional Gas Chromatography: Assessment of methods for baseline correction, peak delineation, and matrix effect elimination for real samples

Jeremy Samuel Arey, Jonas Gros, Saer Samanipour, Petros Dimitriou Christidis, Auréline Grange

Comprehensive two-dimensional gas chromatography (GC x GC) is used widely to separate and measure organic chemicals in complex mixtures. However, approaches to quantify analytes in real, complex samples have not been critically assessed. We quantified 7 PA ...

First day of an oil spill on the open sea: Early mass transfers of hydrocarbons to air and water

Jeremy Samuel Arey, Jonas Gros, Deedar Nabi

During the first hours after release of petroleum at sea, crude oil hydrocarbons partition rapidly into air and water. However limited information is available about very early evaporation and dissolution processes. We report on the composition of the oil ...

Resolving biodegradation patterns of persistent saturated hydrocarbons in weathered oil samples from the Deepwater Horizon disaster

Jeremy Samuel Arey, Jonas Gros

Biodegradation plays a major role in the natural attenuation of oil spills. However, limited information is available about biodegradation of different saturated hydrocarbon classes in surface environments, despite that oils are composed mostly of saturate ...

Mapping environmental partitioning properties of nonpolar complex mixtures by use of GCxGC

Jeremy Samuel Arey, Jonas Gros, Petros Dimitriou Christidis, Deedar Nabi

Comprehensive two-dimensional gas chromatography (GC × GC) is effective for separating and quantifying nonpolar organic chemicals in complex mixtures. Here we present a model to estimate 11 environmental partitioning properties for nonpolar analytes based ...

Oxygenated weathering products of Deepwater Horizon oil come from surprising precursors

Jonas Gros

Following the release of crude oil from the Macondo well in 2010, a wide range of weathering processes acted on the spilled oil. A recent study revealed that samples from this spill were oxidized into oxygenated hydrocarbons (OxHC) comprising more than 50% ...

Robust algorithm for aligning two-dimensional chromatograms

Jeremy Samuel Arey, Jonas Gros, Petros Dimitriou Christidis, Rebecca Rutler, Deedar Nabi

Comprehensive, two-dimensional gas chromatography (GC x GC) chromatogram's typically exhibit run-to-run retention time variability. Chromatogram alignment is often a desirable step prior to further analysis of the data, for example, in studies of environme ...
