... bioaccumulate polycyclic aromatic hydrocarbons (PAHs) from produced water discharges to offshore waters of the Gulf of Mexico. Two platform pairs, each consisting of a produced water-discharging platform and a nearby non-discharging reference platform were selected for monitoring in offshore waters (90 to 260...

... Polycyclic aromatic hydrocarbons (PAHs) are phototoxic to animals and plants. To monitor the toxicity of PAHs and understand their mechanism(s) of action, it is important to develop rapid and accurate bioindicators of effect. In this study, we have analyzed the impact of the anthracene...

... An in vitro ethoxyresorufin O-deethylase (EROD) assay was used to study the ability of individual polycyclic aromatic hydrocarbons (PAHs) and mixtures of PAHs to induce Ah receptor (AhR) mediated cytochrome P4501A activity in PLHC-1 fish hepatoma cells. The purpose was to identify the most...

... This investigation implemented a statistically based sampling program to determine the ambient levels of metals and carcinogenic polycyclic aromatic hydrocarbons in municipalities that meet urban center population criteria within the Piedmont Region of New Jersey. New Jersey Department...

... Semipermeable membrane devices (SPMDs) were used to monitor polycyclic aromatic hydrocarbons (PAHs) in an urban stream. Replicate SPMDs were exposed during seven consecutive 14-day periods and analyzed for PAHs. Relative percent differences (RPDs) were calculated to determine precision...

... (as measured by standard toxicity tests) was virtually absent by 1990–'91, except at a small number of isolated locations. The petroleum residues had degraded below the threshold of acute toxic effects. Measurable polycyclic aromatic hydrocarbon (PAH) levels are, in general, well below those conservatively...

... of differences, thereby avoiding the problem of inherent differences in baseline CPUE levels between bays and the influence of non-random application of oil to bays. Polycyclic aromatic hydrocarbons (PAHs) of petrogenic origin were measured in all bays sampled in this study and levels of PAHs derived from EVC...

... Oil tar is a heterogeneous mixture of petroleum compounds, including polycyclic aromatic hydrocarbons (PAHs). These are a significant health concern because many are suspected and known carcinogens. An oil gasification facility in Pt. Stanley, Ontario, Canada, deposited residual oil tars...

... The potential for bioremediating polycyclic aromatic hydrocarbons (PAHs), the major constituents of creosote, will depend on the response of the sediment bacterial community. The microbial community in sediments from a creosote-polluted freshwater lake was studied. The aim of this study...

... A procedure has been developed that discriminates Exxon Valdez crude from other sources of hydrocarbons found in Prince William Sound and the Gulf of Alaska. The procedure uses polycyclic aromatic hydrocarbon (PAH) distributions, measured by gas chromatography/mass spectrometry (GC/MS...

... The carcinogenic effects of two polycyclic aromatic hydrocarbons (PAHs), benzo( a )pyrene (BaP) and 7,12-dimethylbenz( a )anthracene (DMBA), were examined in the sheepshead minnow ( Cyprinodon variegatus ).
