concentration levels of 16 polycyclic aromatic hydrocarbons (pahs) consisting of naphthalene, acenaphthylene, acenaphthene, fluorine, phenantherene, anthracene, fluor?anthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)p?yrene, dibenzo(a,h)ant?hracene, indeno(1,2,3-cd) pyrene and benzo(g,h,i)perylene were measured in water and sediment samples coll...

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...

Polycyclic Aromatic Hydrocarbons are ubiquitous in the urban atmosphere and one of the most atmospheric pollutants to be identified as suspected carcinogens .The objective of this study was to compare particulate PAH profiles from several sites across Tehran. Atmospheric concentrations of Polycyclic Aromatic Hydrocarbons in Tehran were evaluated to study particulate PAH profiles in different si...

Polycyclic aromatic hydrocarbons in three sections of a dated sediment core from Buzzards Bay, Massachusetts, have been analyzed by gas chromatographic spectrometry. This historical information suggests that sedimentary polycyclic aromatic hydrocarbons, at least at this location, result primarily from the anthropogenic combustion of fossil fuels.

A new electron capture detector (ECD) for the Agilent 6890 Series gas chromatograph (GC) allows very sensitive detection of nitroaromatic compounds at low picogram levels with a linear response over three orders of magnitude. Analysis of Nitroaromatics and Nitro-Polycyclic Aromatic Hydrocarbons by Capillary Gas Chromatography with the Agilent 6890 Micro-ECD This application note describes the p...

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...

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...
