In order to investigate cell-specific differences in the response of in vitro models to environmental toxicants, we compared the capacity of nine polycyclic aromatic hydrocarbons (PAHs) to induce cytochrome P4501A (CYPIA) in primary rainbow trout (Oncorhynchus mykiss) hepatocytes and a rainbow trout liver cell line, RTL-W1. Induction of CYPIA was estimated from the catalytic activity of 7-ethox...

To investigate non-bonded interaction of Phenanthrene and BN nanostructure, geometric structure of Phenanthrene and B12N12 nano-ring with B3LYP method and 6-31g* basis set are optimized by using ab initio gaussian quantum chemical package. The main purpose of this study was to evaluate changes of electronic properties of aromatic compound in presences Nano ring field. Therefore reactivity and s...

Neoplastic diseases, particularly of bottom-dwelling fishes, are more prevalent in coastal areas than in areas that are relatively pristine. Although sediments in many urbanized estuaries contain high concentrations of contaminants, there is little evidence linking a specific organic or inorganic chemical to a particular liver lesion in winter flounder (Pleuronectes americanus), despite increas...

The environmental menace caused by hydrocarbon releasing activities on water bodies have remained a cause for great concern. Such are accompanied the release of highly toxic and carcinogenic polycyclic aromatic hydrocarbons (PAH), which easily biomagnified across food chain, ultimately aggravating adverse health conditions in human. This study was aimed at identifying most important contributor...

polycyclic aromatic hydrocarbons (pahs) such as anthracene, naphthalene, and phenanthren are the most toxic and carcinogenic pollutants which cause severe damages on soil and water resources. in order to remove these materials, biological methods and using potential of local microorganisms of oil contaminated soils are preferred because of cheapness and availability. existing soil microorganism...

The supercritical extraction process is a technique that has increasingly been applied in various industries recent years. Solubility determination the region key feature for this process. However, high expenses and time consuming experiments task obligates need modeling. In study, thermodynamic model proposed to correlate solubility of solid hydrocarbons, namely, 1-hexadecanol, 1-octadecanol, ...

Sorption of phenanthrene onto the natural sediment with low organic carbon content (OC%), organic-free sediment, and kaolinite was investigated through isotherm experiments. Effects of cosolutes (pyrene, 4-n-nonyphenol (NP), and humic acid (HA)) on phenanthrene sorption were also studied by comparing apparent solid-water distribution coefficients (K d (app)) of phenanthrene. Two addition sequen...
