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.
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.
Effects of polynuclear aromatic hydrocarbons
on fishes and shellfish: an overview of research in Virginia.
Sorption properties of polynuclear aromatic hydrocarbons
and sediments: heterocyclic and substituted compounds.
Also in this enormous toxic mix were some 2,500 contaminants: asbestos, fiberglass, drywall dust, and vinyl-coated wiring, along with hydraulic oil and many other fuels and combustion product chemicals involving polyvinyl chloride, PCBs, dioxins, and other polynuclear aromatic hydrocarbons
, as well as lead, copper, iron oxide, and cadmium.
These grades are produced using state-of-the-art production systems with strict process controls to consistently meet FDA limits of polynuclear aromatic hydrocarbons
(PAH) and benzo(a)pyrene.
Two species of flatfish from southern California were evaluated for exposure to polynuclear aromatic hydrocarbons
(PAHs), and DNA damage.
Toxic effects of polynuclear aromatic hydrocarbons
on human breast cancer cells
One for trinitrotoluene is a colorimetric procedure, and the other for carcinogenic polynuclear aromatic hydrocarbons
uses the Quick Test photochemical procedure.
Contamination of the soil with the likes of tar, phenolics, polynuclear aromatic hydrocarbons
(PAH) and volatile aromatics (BTX) is not unusual.
To plan future study designs, the RTI team will collect exposure data for chlorpyrifos and other pesticides, and for benzo(a)pyrene and other polynuclear aromatic hydrocarbons
