Advancement in oil forensics through the addition of polycyclic aromatic sulfur heterocycles as biomarkers in diagnostic ratios

Autor: Taylor Filewood, Honoria Kwok, Pamela Brunswick, Jeffrey Yan, Jessica E. Ollinik, Christopher Cote, Marcus Kim, Graham van Aggelen, Caren C. Helbing, Dayue Shang

Publikováno v: Journal of hazardous materials. 435

In current oil spill forensics, diagnostic ratios of hydrocarbon biomarker responses are commonly used to compare oil spill samples to source materials in order to determine the identity of the oil. This well recognized procedure was developed by the

Publikováno v: Analytical Methods. 12:5236-5246

Frequent small-scale environmental releases of lubricating (lube) oils have deleterious effects on aquatic ecosystems. In the event of a spill, oil fingerprinting is critical to source attribution, clean-up procedures, and liability assignment. Oil f

A rapid gas chromatography quadrupole time-of-flight mass spectrometry method for the determination of polycyclic aromatic hydrocarbons and sulfur heterocycles in spilled crude oils

Autor: Taylor Filewood, Honoria Kwok, Pamela Brunswick, Jeffrey Yan, Jessica E. Ollinik, Christopher Cote, Marcus Kim, Graham van Aggelen, Caren C. Helbing, Dayue Shang

Publikováno v: Analytical methods : advancing methods and applications. 14(7)

Spilled crude oil samples contain various toxic compounds including polycyclic aromatic hydrocarbons (PAHs) as well as sulfur heterocycles (PASHs) and their related alkylated forms (APAHs and APASHs). In this study, a method was successfully develope

Thyroid hormones (THs) are important developmental regulators in vertebrates, including during the metamorphosis of a tadpole into a frog. Metamorphosis is a post-embryonic developmental period initiated by TH production in the tadpole thyroid gland.

Improved oil spill dispersant monitoring in seawater using dual tracers: Dioctyl and monoctyl sulfosuccinates sourced from corexit EC9500A

Autor: Graham van Aggelen, Dayue Shang, Ben Fieldhouse, Jeffrey Yan, Marcus Kim, Pamela Brunswick, Ceara MacInnis, Carl E. Brown

Publikováno v: Journal of Chromatography A. 1598:113-121

A high resolution mass spectrometry method was developed for the environmental impact monitoring of oil spill dispersants. Previously reported instability of dioctyl sulfosuccinate (DOSS) dispersant tracer was addressed by the new procedure. The meth
