Polycyclic
aromatic hydrocarbons (PAHs) are assembly of organic compounds which are abundantly present in the atmosphere of heavily populated areas which are having vehicular exhausts as well (Zheng, 2009).
According to the researchers Chisom Obasi, Nkechi Okoye, Uche Ekpunobi and Rosemary Arinze of the Department of Pure and Industrial Chemistry, Faculty of Physical Sciences in the research titled 'Distribution and Risk Assessment of Polycyclic
Aromatic Hydrocarbon Contamination Arising from Uncontrolled Electronic Waste Recycling in Aba, Nigeria,' the objective of the research was to study the level of polycyclic
aromatic hydrocarbons in soils and the potential human health and ecological risk assessed.
Summary: TEHRAN (FNA)- Astronomers have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and truly massive ones known as polycyclic
aromatic hydrocarbons.
One example of these are polycyclic
aromatic hydrocarbons (PAHs) that are considered as priority pollutants by the European Union (EU) and the Environmental Protection Agency (EPA) because they are carcinogenic and they can genetically mutate [3, 5-8] and what is more, these compounds could activate oxidative stress of DNA, hence damaging metabolic activation and the generation of reactive kinds of oxygen [9, 10] making the extraction, preconcentration, and determination of these compounds in the environment very important [11, 12].
Hepatic concentrations of total polycyclic
aromatic hydrocarbons (n = 5 birds) were similar to background concentrations of polycyclic
aromatic hydrocarbons previously found in yellow-eyed penguins from the South Island of New Zealand, but there were significantly higher concentrations of 1-methylnapthelene and 2-methylnapthelene in the birds found dead in this mortality cluster.
The health services on Friday recalled a smoked-sausage brand after lab tests indicated that the product exceeds the permitted level of Polycyclic
Aromatic Hydrocarbons.
Polycyclic
aromatic hydrocarbons (PAHs) are organic substances that contain two or more benzene rings.
Plants can adsorb polycyclic
aromatic hydrocarbons especially from air [6].
Polycyclic
aromatic hydrocarbons (PAHs), a group of typical chemicals containing two or more aromatic rings, are widely distributed in water [1],soil, sediment [2-5],and air [6].PAHs have been attracting increasing attention, because many are known to be carcinogenic, mutagenic, or teratogenic [7, 8], which are serious health threats to organisms.
