conclusions concerning the ability of salicorniaeuropea to survive in the contaminated areas, it might be suitable that endemic types of this plant would be cultivated in contaminated coast lines. results the highest uptake was at eight mg crude oil, per one g of soil and the least uptake was at 13.75 mg crude oil, per one g of soil. it seems that physical characteristics of crude oil are the m...

There is currently scarce information on the occurrence and distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in the air from industrial estates in Nigeria. Hence, the present study aims to evaluate the extent and sources of pollution of polycyclic aromatic hydrocarbons in the air from some industrial estates in Lagos and Ogun States, Nigeria. Ten air samples have been collected from the...

The present paper provides results of a study on heterotrophic bacteria occurrence and quantity in the biofilm and subsurface water of lake Jeziorak Maty. Degradation of several polycyclic aromatic hydrocarbons (PAH's) (anthracene, naphthalene) by neustonic and planktonic bacteria have been examined. It has been discovered that some aromatic hydrocarbons were better decomposed by neustonic bact...

This paper examines the possible presence, distribution, nature and sources of 18 Polycyclic Aromatic Hydrocarbons (PAHs) as constituent of the muds pool collected in Vulcano Aeolian Island. PAHs are important from environmental and toxicological point of view. Analysis was performed by gas chromatography/mass spectrometry (GC/MS) in selected ion monitoring (SIM). The total concentration of Pol...

The algorithmic construction of formula periodic tables for polycyclic conjugated hydrocarbons is detailed. The symmetries associated with this construction are identified. The formula periodic table for benzenoids (Table PAH6) exhibits a one-to-one mapping onto the formula periodic table for fluorenoids/fluoranthenoids minus the constant-isomer fluorenoid/fluoranthenoid formulas and the formul...

This contribution summarizes methods to compare bonded stationary phases for the compound-class HPLC separations of unsaturated polycyclic hydrocarbons and polar compounds. These strategies are based on the physical chemistry behavior of the functional group of the bonded stationary phase, behavior of the unsaturated polycyclic hydrocarbons under isocratic and gradient elution, regression analy...

A pathway of research is described, leading from the finding of an inhibitory effect of 3-methylcholanthrene on the carcinogenicity of an aminoazo dye, to the induction of drug-metabolizing enzymes by 3-methylcholanthrene, benzo[a]pyrene, and other polycyclic aromatic hydrocarbons, to the demonstration of enhanced drug metabolism in cigarette smokers, coffee drinkers, and people who eat charcoa...

in this study, the degradation potential of five polycyclic aromatic hydrocarbons (pahs) by aerobic mixed bacterial cultures was investigated. microorganisms were isolated from hydrocarbon contaminated soils of shadegan wetland located in southwest of iran. the degradation experiments were conducted in liquid cultures. pah or pahs concentration was 100 mg/l at the beginning of degradation exper...

in this study, oxic and anoxic microcosms were constructed with aquifer sediment collected from the vicinity of a municipal solid waste composting site.phenanthrene was used as a model pah compound. the changes of bacterial and archaeal communities in microcosms were characterized with terminal restriction fragment length polymorphism. 16s rrna gene clone library analysis was also used to inves...
