polycyclic aromatic hydrocarbons (pahs) are one of the most important organic pollutants frequently found in the environment. in this experiment, the effect of phytoremediation as a cost effective method was studied on the concentration of anthracene (c14h10) which is one of pahs. the effect of sorghum (v1), hairy vetch (v2) and oat (v3) was studied under four concentrations of anthracene (s1, ...

results the soil was largely composed of silt and clay (silt:41 - 42%, clay: 40 - 43%, sand: 15 - 18%). the average moisture content of the saturated soil was 12.96%,; average electricity conductivity was 18.64 dsm-1; average ph of the paste was 8.36; and average percentage of organic carbon was 0.19%. result of the laboratory analysis reported the average content of total nitrogen as 0.026%, p...

The biodegradability of polycyclic aromatic hydrocarbons such as naphthalene, fluorene, anthracene and phenanthrene by a halotolerant bacterial consortium isolated from marine environment was investigated. The polycyclic aromatic hydrocarbons degrading bacterial consortium was enriched from mixture saline water samples collected from Chennai (Port of Chennai, salt pan), India. The consortium po...

A total of 10 surface soil samples representing the entire area of Linfen City were collected and analyzed for the presence of 16 polycyclic aromatic hydrocarbons. The total polycyclic aromatic hydrocarbon concentration ranged from 1.1 to 63.7 microg g(-1). Analysis of the sources of contamination revealed that polycyclic aromatic hydrocarbons in the soil were derived from combustion sources. S...

vehicle exhaust is a major source of exposure to polycyclic aromatic hydrocarbons (pahs) found in the urban atmosphere. newsagents usually work close to heavy traffic flow. the purpose of this study was to assess the breathing zone exposure of newsagents to pahs found in the urban atmosphere of tehran city during summer and autumn seasons and comparing the levels of exposure in both seasons.fif...

polycyclic aromatic hydrocarbons (pahs) are toxic pollutants released by various urban combustion sources. tehran is the largest city in iran with a population of about 8 million and it is faced with serious air quality problems. the gas phase samples collected from 21 sites in tehran area throughout year 2005. the samples‘ pahs were collected using a skc trapping consisting of glass cartridg...

Hydrocarbons Hannah Zane Abstract: New three-dimensional polycyclic aromatic hydrocarbons were synthesized using a zirconium mediated biphenylation reaction. Three-dimensional PAHs exhibit better solubility than their two-dimensional counterparts, as well as allowing for more applications based on their more complex structure. Introduction: Our research focuses on the synthesis of new and inter...

The methodology for the prediction of properties of environmental relevance of polycyclic aromatic hydrocarbons based on the conductor-like screening model for real solvents (COSMO-RS/COSMOtherm) is presented and evaluated, with a special focus on the aqueous solubility of polycyclic aromatic hydrocarbons and related aromatic hydrocarbons (PAHs). It is shown that the solubility predictions as w...

polycyclic aromatic hydrocarbons (pahs) in the priority controlling list of us epa weresystematically evaluated in surface sediments in dianchi lake and its estuaries. total pah concentrations(σpahs) varied from 210 to 11,070 ng/g dry weight (d.w.) in dianchi lake, and from 230 to 12,271 ng/g d.w.in the estuaries. σpahs in sediments from caohai section were higher than those from waihai section...
