The soil was found to be tainted by several contaminants, including polynuclear aromatic hydrocarbons
, or PAHs; arsenic, lead and nickel; cyanide; and volatile organic compounds, or VOCs.
Louis River was polluted with polynuclear aromatic hydrocarbons
and heavy metals left over from the areas industrial past.

However, unsafe levels of polychlorinated biphenyls (PCBs), mercury, lead and polynuclear aromatic hydrocarbons
(PAHs) remain present.
There are three peak groups of aromatic hydrocarbons (AHs) in the TICs of Biluo Co oil shale samples: a peak group of naphthalenes and alkyl naphthalenes, a peak group of phenanthrenes and alkyl phenanthrenes, and a peak group of aromatic sterenes and other polynuclear aromatic hydrocarbons
The contamination consists mostly of chemicals called polynuclear aromatic hydrocarbons
, as well as benzene, toluene and xylenes.

They also expect that levels of any of these contaminants should be below detectable limits via mass spectrometry, for polynuclear aromatic hydrocarbons
or chemiluminescence for N-nitrosoamines.
The researchers say evidence for cooked carbohydrates is confirmed by both the cracked/roasted starch granules observed microscopically and the molecular evidence for cooking and exposure to wood smoke or smoked food in the form of a range of chemical markers including methyl esters, phenols, and polynuclear aromatic hydrocarbons
found in dental calculus.
Contaminants found at the sites include benzene, heavy metals, polynuclear aromatic hydrocarbons
(PAHs), volatile organic compounds (VOCs), and trichloroethylene (TCE).
