“…There can be variations in the response of an FID to various HCs as a result of HC class (i.e., the type of carbon bond or the degree of oxidation) and flame condition, but these errors are generally less than 10%. 38 The THD was calibrated…”

Concerns have been expressed that emissions of volatile hydrocarbons (HCs) from bioremediation facilities containing soils contaminated with petroleum HCs may negatively impact regional air quality or human health. Little information is available regarding the emission of HCs from bioremediation sites, and few field studies have been performed during which the flux of HCs has been directly measured during bioremediation. To aid in answering questions about the impact of bioremediation facilities on the atmospheric environment, a two-part field study was conducted over summer 1996 at a remote landfarm in northern Ontario where diesel fuel-contaminated soil was undergoing bioremediation. Volatile total hydrocarbon (THC) atmospheric flux measurements were successfully taken over 18 days using a flux gradient micrometeorological technique incorporating a THC detector constructed in-house. Peak THC emissions reached 131 µg C/m 2 /sec shortly after implementation and tilling of the landfarm soil. The influence of soil temperature and tillage on THC emissions was examined. Off-site inhalation exposure was considered with the aid of an areal source model and results from speciated air samples collected on sorbent tubes and analyzed via gas chromatography/mass spectrometry (GCMS) techniques.

“…These have traditionally been quantified by gas chromatography (GC) using flame ionization detection (FID), a very tedious procedure. Recently traditional GC/FID techniques have been shown to significantly under‐detect higher molecular weight hydrocarbons [Sigsby et al, 1990]. An automated “on‐line” sampling and sample concentrations system for GC measurement of trace organics has been described by Rudolph et al [1990].…”
