FVT of I , 1 -dichloroand/or 1 -chloroethenyl substituted PAHs gives access to the CP-PAH's pyracylene (l), cyclopenta[cd]pyrene (12) and benz[ghi]fluoranthene (13), cyclopent[hi]aceanthrylene (18) and cyclopent[hi]acephenanthrylene (19), and the novel cyclopenta[cd]fluoranthene (22) and isomeric cyclopent[fg](25a), cyclopent[ik](25b) and cyclopent[rnn]acepyrylene (25c), respectively. The prope...

Early explorers to Antarctica built wooden huts and brought huge quantities of supplies and equipment to support their geographical and scientific studies for several years. When the expeditions ended and relief ships arrived, a rapid exodus frequently allowed only essential items to be taken north. The huts and thousands of items were left behind. Fuel depots with unused containers of petroleu...

The status of organic pollution in groundwater in eastern China along the Grand Canal from Hangzhou to Beijing was evaluated. Forty-two semi-volatile organic contaminants were analyzed, including 16 polycyclic aromatic hydrocarbons (PAHs), seven polychlorinated biphenyls (PCBs), 12 organochlorine pesticides (OCPs) and seven organophosphorus pesticides (OPPs). Among the detected contaminants, PA...

In this study, PAHs and their transformed PAH products (TPPs) in road dust were subjected to UV driven photolysis, then extracted using simultaneous pressurized fluid extraction, analysed Shimadzu Triple Quadrupole GC/MS. The results of the analysis used investigate robustness reliability 14 existing diagnostic ratios (DRs) two newly proposed molecular DRs that are relevant for characterizing s...

Diverse contaminants released into the environment through progress of urbanization and industrialization adversely affect human health. Among various sources of contaminants, especially, in big cities, automobiles play a significant role in aggravating the pollution. Various pollutants viz., heavy metals (Pb, Mn, Ni, Zn, As, Hg, Cd) and Polyaromatic hydrocarbons (Benzo-apyrene, fluoranthene, p...

A monitoring system was used to examine the behavioral response of fathead minnows (Pimephales promelas) to plumes of the polycyclic aromatic hydrocarbon fluoranthene. Previously unexposed fish and fish surviving acute exposure to fluoranthene were presented with three different concentrations of fluoranthene. Both groups of fish avoided fluoranthene. Pre-exposure did not enhance or diminish av...

A pathway for the biotransformation of the environmental pollutant and high-molecular weight polycyclic aromatic hydrocarbon (PAH) benzo[k]fluoranthene by a soil bacterium was constructed through analyses of results from liquid chromatography negative electrospray ionization tandem mass spectrometry (LC/ESI(-)-MS/MS). Exposure of Sphingobium sp. strain KK22 to benzo[k]fluoranthene resulted in t...

Sixteen polycyclic aromatic hydrocarbons (PAHs) were screened for their ability to be photocytotoxic to a cell line from the rainbow trout gill, RTgill-W1. PAHs could be divided into one of three groups: incapable of being photocytotoxic, able to be both photocytotoxic and directly cytotoxic, or capable of being only photocytotoxic. Photocytotoxicity was distinct from direct cytotoxicity in tha...

Ligand exchange reactions between [Cp*Ru(NCMe)3][PF6], where Cp* represents η(5)-C5Me5, and the polycyclic aromatic hydrocarbons (PAHs) pyrene, acenaphthylene and fluoranthene afforded the known [Cp*Ru(η(6)-pyrene)][PF6] (1) and the new mixed sandwiches [Cp*Ru(η(6)-acenaphthylene)][PF6] (2) and [Cp*Ru(η(6)-fluoranthene)][PF6] (3), respectively, isolated in quantitative yields (94-100%). Complex...
