Effect Of Ultraviolet Radiation On The Aliphatic And Polycyclic Aromatic Hydrocarbon Profiles Of Agbabu Natural Bitumen
The quality of wide a variety of synthetic or naturally occurring materials which are used for outdoor applications are known to be adversely affected by environmental factors. These materials absorb solar ultraviolet radiation leading to changes in their structures and compositions. The consequences of these changes lead to degradation of the materials. Bitumen is one of the materials which is...
متن کاملBitumens and bitumen emissions, and some heterocyclic polycyclic aromatic hydrocarbons.
1190 www.thelancet.com/oncology Vol 12 December 2011 In October, 2011, 16 experts from nine countries met at the International Agency for Research on Cancer (IARC) in Lyon, France, to reassess the carcinogenicity of bitumens and their emissions, and of some N-heterocyclic and S-heterocyclic polycyclic aromatic hydrocarbons (PAHs). These assessments will be published as Volume 103 of the IARC Mo...
متن کاملIntact and photomodified polycyclic aromatic hydrocarbons inhibit photosynthesis in natural assemblages of Lake Erie phytoplankton exposed to solar radiation.
Recently, there has been a trend toward less turbid water and greater light penetration in parts of western Lake Erie. This could lead to greater phototoxicity from sediment-bound polycyclic aromatic hydrocarbons. To test photosynthesis as a bioindicator of contaminant impacts on algae, water samples containing natural assemblages of phytoplankton were collected from the western and central bas...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملSample preparation procedure for the determination of polycyclic aromatic hydrocarbons in petroleum vacuum residue and bitumen
This paper describes a novel method of sample preparation for the determination of trace concentrations of polycyclic aromatic hydrocarbons (PAHs) in high-boiling petroleum products. Limits of quantitation of the investigated PAHs in materials of this type range from tens of nanograms per kilogram to <20 μg/kg. The studies revealed that in order to separate most of interferences from the analyt...
