Use of compound-specific stable isotope analysis to source anthropogenic natural gas-derived polycyclic aromatic hydrocarbons in a lagoon sediment

Article Abstract:

This article discusses the first identification of polycyclic aromatic hydrocarbons (PAHs) in an extremely low carbon stable isotopic ratio environment. Evidence was gathered to suggest that PAHs have, for the most part, been made by a high-temperature industrial process using biogenic natural gas. Biodegradation is assumed to be responsible for the large variability in PAH isotopic values.

Bacteriogenic ethane in near-surface aquifers: implications for leaking hydrocarbon well bores

Article Abstract:

A study was conducted to figure out the longstanding uncertainty regarding the isotopic signature of bacteriogenic and thermogenic hydrocarbon gas. Well bore leakage cases in the Western Canadian Sedimentary Basin were studied. The article breaks down the study into an introduction, sampling sites and methodolgy, and results and discussion.

Effects of reducing lead in gasoline; An analysis of the international experience

Article Abstract:

This article presents a analysis of the relation between the use of lead in gasoline and population blood levels from 19 studies from six continents. In 17 of the studies, there are data changes in blood lead levels before and after the changes in use of lead in gasoline. In 11 of the studies, there are data on air lead levels. The analysis of the data suggests that reductions in gasoline lead levels have been a major causal factor in the observed reductions in population blood lead levels at these locations. Tables and cites are included.
