Is aromatic carcinogenic?

This book provides an overview on the molecular mode of action of carcinogenic polycyclic aromatic hydrocarbons (PAHs). Many PAHs are strong carcinogens in rodent bioassays and have been linked to increased incidences of various types of cancer in humans. …

Are aromatic compounds non carcinogenic?

ABSTRACT. Polycyclic aromatic hydrocarbons (PAHs) are a group of compounds consisting of two or more fused aromatic rings. Many PAHs and their epoxides are highly toxic, mutagenic and/or carcinogenic to microorganisms as well as to higher forms of life including humans.

What are the aromatic hydrocarbons that cause cancer and why?

Polycyclic aromatic hydrocarbons (PAHs) are made whenever substances are burned. PAHs are also found at former coal-gasification sites. Breathing smoke or coming into contact with contaminated soil exposes people to PAHs. Some PAHs may cause cancer and may affect the eyes, kidneys, and liver.

Why is aromatic hydrocarbon important?

Although originally named for their sweet odor, aromatic hydrocarbons are more important than just creating pleasant aromas. Aromatic hydrocarbons are cyclical groups of carbon atoms that have delocalized electrons, which leads to increased stability.

Is pah a carcinogen?

The carcinogenicity of certain PAHs is well established in laboratory animals. Increased incidences of lung, skin, and bladder cancers are associated with occupational exposure to PAHs. Epidemiologic reports of PAH-exposed workers have noted increased incidences of skin, lung, bladder, and gastrointestinal cancers.

What is the importance of aromatic hydrocarbons?

One of the main uses for aromatic hydrocarbons is as a non-polar solvent for other molecules. Thus, aromatic hydrocarbons can be used as additives in gasoline, paints, lacquers, and other solutions. Their low reactivity also contributes to their use as a solvent.

Is considered natural source of aromatic compounds?

Aromatic compounds are cyclic compounds in which all ring atoms participate in a network of π bonds, resulting in unusual stability. Aromatic compounds are less reactive than alkenes, making them useful industrial solvents for nonpolar compounds. Aromatic compounds are produced from petroleum and coal tar.
