(france-bourges: Technical inspection and testing services)
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
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.
The mutation may have offered ancient humans a sweet spot in effectively processing some of these toxins - such as dioxins and polycyclic aromatic hydrocarbons
- compared to other hominins.
The present study entails the quantification and evaluation of potential risk due to Polycyclic Aromatic Hydrocarbons
(PAHs) which is one of the known organic pollutants from vehicular, power generation system's exhaust and other industrial activities.
Summary: Aliphatic hydrocarbons including resolved aliphatics (C11-C30), isoprenoids (phytane and pristane) and unresolved complex mixture, as well as total aromatic hydrocarbons
were analyzed in 25 surface sediment samples represented five sites along Jeddah coast, Red Sea.
POLYCYCLIC AROMATIC HYDROCARBONS
(PAHS) I: TOXICITY, POPULATION EXPOSURE AND INVOLVED FOODS.
Hydrocarbon degrading bacteria were isolated from the petrol contaminated soil of Karachi to determine their biodegradation capabilities of aromatic hydrocarbons
such as xylene, phenanthrene, naphthalene, biphenyl and anthracene.
