Other organic pollutants present in groundwater andderived from industrial operations are the polycyclic aromatic hydrocarbons(PAHs).
Phenanthrene is a polycyclic aromatic hydrocarbon composed of three fused benzene rings.
Luckily, there are other sources of musk available, including plants like the Abelmoschus moschatus and Amgelica archangelica,as well as several chemical compounds including aromatic nitro musks, polycyclic musks and macrocyclic musk.
Pyrazine ring is a component of various polycyclic compounds of industrial and biological importance.
Polycyclic aromatic hydrocarbons are neutral, non-polar molecules found in coal and tar deposits.
The pyrazine ring is a component of many polycyclic compounds of biological or industrial significance.
Polycyclic aromatic compounds above three rings have low solubility and low vapor pressure in water.
Environmental organic contaminants: polycyclic aromatic hydrocarbons, polychlorinated biphenyls, dioxins.
Polycyclic aromatic compounds are therefore more commonly found in the soil and in sediments than in water and air.
In 2002, a study was conducted to check the concentrations of polycyclic aromatic hydrocarbons(PAHs) in fish and shellfish species that locals consume from the lake.
Polycyclic aromatic compounds can destroy genetic material in the body, trigger the growth of cancer cells and increase the incidence of cancer.
Clinical trial reports indicate that long-term exposure to high concentrations of polycyclic aromatic compounds can cause skin cancer, lung cancer, stomach cancer and liver cancer.
Polycyclic aromatic hydrocarbons are molecules with two or more simple aromatic rings fused together by sharing two neighboring carbon atoms.
They can be divided into three major classes:aromatic nitro musks, polycyclic musk compounds, and macrocyclic musk compounds.[1] The first two groups have broad uses in industry ranging from cosmetics to detergents.
In addition, oil spills can also harm air quality.[48] The chemicals in crude oil are mostly hydrocarbons that contains toxic chemicals such as benzenes, toluene,poly-aromatic hydrocarbon and oxygenated polycyclic aromatic hydrocarbons.
These ligands are mostly polycyclic, aromatic, and planar, and therefore often make good nucleic acid stains.
It is among the reactions in phase II drug metabolism, frequently effective in rendering a xenobiotic less active from a pharmacological and toxicological standpoint, but sometimes playing a role in the activation of xenobiotics(e.g. aromatic amines,methyl-substituted polycyclic aromatic hydrocarbons).
Pyrimidine, like polycyclic aromatic hydrocarbons(PAHs), the most carbon-rich chemical found in the universe, may have been formed in red giants or in interstellar cosmic dust and gas clouds.
The detection of organic molecules,including polycyclic aromatic hydrocarbons, in significant quantities in comets has led to speculation that comets or meteorites may have brought the precursors of life-or even life itself-to Earth.
Pyrimidine, like polycyclic aromatic hydrocarbons PAHs, the most carbon-rich chemical found in the universe, may have been formed in red giants or in interstellar dust and gas clouds, according to the scientists.
Compounds including heavy metals like lead, mercury, zinc, and cadmium,organics like polychlorinated biphenyls(PCBs) and polycyclic aromatic hydrocarbons(PAHs), fire retardants, and other substances are resistant to breakdown.[1] These contaminants can come from a variety of sources including human sewage sludge, mining operations, vehicle emissions, fossil fuel combustion, urban runoff, industrial operations and landfills.[2].
Polycyclic aromatic hydrocarbons(PAHs, also polyaromatic hydrocarbons or polynuclear aromatic hydrocarbons) are hydrocarbons-organic compounds containing only carbon and hydrogen-that are composed of multiple aromatic rings(organic rings in which the electrons are delocalized).
