A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.

This Public Health Statement is the summary chapter from the Toxicological Profile for polycyclic aromatic hydrocarbons (PAHs). It is one in a series of Public Health Statements about hazardous substances and their health effects.

Nov 20, 2021 · 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).

Jul 23, 2013 · Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned. PAHs generated from these sources can bind to or form small particles in the air.

PAHs are a class of organic compounds produced by incomplete combustion or high-pressure processes. Often, PAHs consist of three or more fused benzene rings containing only carbon and hydrogen. PAHs are solids with low volatility at room temperature.

Polycyclic aromatic hydrocarbons (PAHs) are a group of over 100 different chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat.

Mar 1, 2016 · Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants generated primarily during the incomplete combustion of organic materials (e.g. coal, oil, petrol, and wood).

Polycyclic aromatic hydrocarbons (PAHs) are a group of over 100 different chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat. PAHs are usually found as a mixture containing two or more of these compounds, such as soot. Some PAHs are manufactured.

The most common subclass of POM is the polycyclic aromatic hydrocarbons (PAHs). These compounds contain only carbon and hydrogen (1). PAHs are a large group of organic compounds with two or more fused aromatic (benzene) rings (2).

Polycyclic Aromatic Hydrocarbons (PAHs), also known as polyaromatic hydrocarbons, are organic compounds containing only carbon and hydrogen and composed of multiple aromatic rings (Figure 1). These compounds are formed when oxygen is limited, and incomplete combustion of organic matter such as wood, tobacco products, or fossil fuels occurs.
