Phenanthrene is used to make dyes, plastics, pesticides, explosives, and drugs. It has also been used to make bile acids, cholesterol and steroids. [3] Phenanthrene occurs naturally and also is a man-made chemical. Commonly, humans are exposed to phenanthrene through inhalation of cigarette smoke, but there are many routes of exposure.
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.
As a result, while anthracene reacts with maleic acid, phenanthrene does not, and triphenylene is the most stable species of these three. [ 1 ] Three Clar structures with an increasing number of π-sextets: anthracene (on the left), phenanthrene (in the middle), and triphenylene (on the right).
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation. [13]
Dibenz[a,h]anthracene, Benzo[k]tetraphene or 1,2:5,6-Dibenzanthracene is an organic compound with the chemical formula C 22 H 14. It is a polycyclic aromatic hydrocarbon (PAH) made of five fused benzene rings. It is a fused five-ringed PAH which is common as a pollutant of smoke and oils.
Protein is an essential macronutrient for everyone, and if you’re taking a weight loss drug, such as GLP-1 medications, you should be extra mindful about your intake.This is because muscle loss ...
A metabolite of benzopyrene forms an intercalated DNA adduct, at center. In molecular genetics, a DNA adduct is a segment of DNA bound to a cancer-causing chemical. This process could lead to the development of cancerous cells, or carcinogenesis. DNA adducts in scientific experiments are used as biomarkers of exposure.
As of 2010, the IARC (International Agency for Research on Cancer) has classified dibenz(a,j)anthracene as possibly carcinogenic to humans, grouped into IARC group 2B.No epidemiological studies on human exposure to dibenz(a,j)anthracene as an individual PAH exist, because PAHs always occur as components of complex chemical mixtures and never occur in isolation in the environment.
