This work aims to characterize levels and phase distribution of polycyclic aromatic hydrocarbons (PAHs) in indoor air of preschool environment and to assess the impact of outdoor PAH emissions to indoor environment. Gaseous and particulate (PM1 and PM(2.5)) PAHs (16 USEPA priority pollutants, plus dibenzo[a,l]pyrene, and benzo[j]fluoranthene) were concurrently sampled indoors and outdoors in on...

Benthic amphipod, Grandidierella japonica widely inhabits the Korean coastal waters and is developed as a standard test species for sediment toxicity tests. We exposed G. japonica to various pollutants including 4 kinds of inorganic metals (Ag, Cd, Cu and Hg), tributyltin [TBT], ammonia and 7 polycyclic aromatic hydrocarbon (PAH) compounds (acenaphthene, chrysene, fluoranthene, fluorene, naphth...

This paper presents the results of PAH determination adsorbed on fine and ultrafine particles emitted to the air from diesel exhaust, with a special emphasis on sample preparation procedure prior to HPLC-FL analysis. Samples were taken with a personal environmental monitor and personal cascade impactor in order to ensure size-segregated sampling of air particulate matter (in the range of the fo...

This is the Final Statement of Reasons for specific regulatory levels posing no significant risk for eight chemicals listed as known to the State to cause cancer under the Safe Drinking Water and Toxic Enforcement Act of 1986 (hereinafter “the Act” or Proposition 65; Health and Safety Code 25249.5 et seq.). On June 13, 2003, the Office of Environmental Health Hazard Assessment (OEHHA) issued a ...

Solubilisation of six polycyclic aromatic hydrocarbons (PAHs) (acenaphthene, anthracene, fluoranthene, fluorene, phenanthrene and pyrene) by three synthetic cyclodextrins (CDs) (2-hydroxypropyl-β-CD, hydroxypropyl-γ-CD and randomly methylated-β-CD) was investigated in order to select the CD which presents the greatest increase in solubility and better complexation parameters for its use in cont...

Inoculation with efficient microbes had been proved to be the most important way for the bioremediation of polluted environments. For the treatment of abandoned site of Beijing Coking Chemical Plant contaminated with high level of high-molecular-weight polycyclic aromatic hydrocarbons (HMW-PAHs), a bacterial consortium capable of degrading HMW-PAHs, designated 1-18-1, was enriched and screened ...

This study assessed the heavy metals and polycyclic aromatic hydrocarbons (PAHs) pollutant in soil around petrol filling stations automobile mechanic workshops. Samples of were acquired from depth range 0–15 cm. Toxic analyzed with atomic absorption spectrophotometry. The PAHs using phytochemical chromatographic analysis by Soxhlet extraction method. tested was weakly acidic (6.12–6.81). trend ...

This study investigated the profiling of polycyclic aromatic hydrocarbon- (PAH-) induced genotoxicity in cell lines and zebrafish. Each type of cells displayed different proportionality of apoptosis. Mitochondrial DNA (mtDNA) copy number was dramatically elevated after 5-day treatment of fluoranthene and pyrene. The notable deregulated proteins for PAHs exposure were displayed as follows: lamin...

To investigate the effects of polycyclic aromatic hydrocarbons (PAHs) and metals on the population reproduction, antioxidative defense system and cell ultrastructure of the marine diatom, fluoranthene and Cu2+ were selected to test their toxicity to Phaeodactylum tricorntum, in the laboratory. The results indicated that both fluoranthene and Cu2+ inhibited population reproduction of P. tricornt...

Fluoranthene is a ubiquitous environmental pollutant. Although fluoranthene is mutagenic in bacterial and mammalian in vitro cell systems following metabolic activation by rat liver fraction, information on in vivo mutagenicity is lacking and studies on tumour initiating activity in mice are equivocal. In the present study, the potential genetic hazard to man was assessed using the mouse bone m...
