About Coal Tar and Polycyclic Aromatic Hydrocarbons (PAHs)
The Air and PAHs. Most PAHs, whether the result of natural or anthropogenic (man-made) processes, are released into the air. PAHs are found in ambient air in both gaseous and on particles. PAHs are widespread in ambient air being found in urban, suburban and rural locations. A wide range of PAHs can be found in the atmosphere.
Coal-Tar-Based Pavement Sealcoat, PAHs, and Environmental
Coal tar and coal-tar pitch, both used in sealcoat products, have extremely high concentrations of PAHs, and both are classified as known human carcinogens. Coal-tar-based sealcoat products typically are 20 to 35 percent coal tar or coal-tar pitch. Asphalt and asphalt-based sealcoat products have much lower concentrations of PAHs.
Polycyclic Aromatic Hydrocarbons: Sources, Toxicity, and
Nov 05, 2020 · Polycyclic Aromatic Hydrocarbons: Physico-chemical Properties, Sources of Pollution, and Routes of Exposure. Polycyclic aromatic hydrocarbons are organic pollutants and composed of two or more fused aromatic rings of carbon and hydrogen atoms, which are primarily colorless, white, or pale yellow solid compounds (Abdel-Shafy and Mansour, 2016; Suman et al., 2016).

USGS NAWQA: FAQ Parking-Lot Sealcoat: A Major Source of
Polycyclic aromatic hydrocarbons (or PAHs) are a group of organic contaminants that form from the incomplete combustion of hydrocarbons, such as coal. Coal tar is a byproduct of the coking of coal, and can contain 50 percent or more PAHs by weight. Sealcoat is a black liquid that is sprayed or painted on asphalt pavement in an effort to protect
Assessment of gaseous emissions produced on site by
Sep 30, 2014 · Available technologies are known as the "wet" and "dry" processes. In the "wet" process, CR is preliminarily mixed with bitumen, thus obtaining a very ductile and elastic modified binder, also known as "asphalt rubber" (AR) [ASTM D6114-09], that is then combined with aggregates in the hot mix plant.
RE: Amendments to the High Impact Land Use Ordinance
Asphalt cement typically comprises 5% (0.05) of the total hot mix plant production. Fugitive air emissions equal 1.07% (0.0107) of the consumed asphalt cement.3 So, for an asphalt plant producing 300,000 tons of hot mix asphalt per year: 300,000 tons hot mix x 0.05 = 15,000 tons/year of asphalt cement consumed.
