Phytoremediation is a promising technique for cleaning petroleum contaminated soils. In this study, the effects of two grass species (Festuca arundinacea Schreb. and Festuca pratensis Huds.), infected (E(+)) and non-infected (E(-)) by endophytic fungi (Neotyphodium coenophialum and Neotyphodium uncinatum, respectively) on the degradation of petroleum hydrocarbons in an aged petroleum contaminat...

Quantitative information regarding the endmember composition of the gas and oil that flowed from the Macondo well during the Deepwater Horizon oil spill is essential for determining the oil flow rate, total oil volume released, and trajectories and fates of hydrocarbon components in the marine environment. Using isobaric gas-tight samplers, we collected discrete samples directly above the Macon...

INTRODUCTION — Hydrocarbons are organic substances that contain carbon and hydrogen; they are liquid at room temperature [1] . All petroleum distillates (eg, kerosene, gasoline, mineral seal oils, and naphtha) are hydrocarbons; however, not all hydrocarbons are petroleum distillates. Hydrocarbons also often are mixed with agents that have systemic toxicity such as camphor, aniline dyes, heavy m...

The effect of addition of a microbial consortium (A) with 22 micro-organisms on the large scale (400 m3) bioremediation of municipal waste water contaminated with petroleum hydrocarbons was evaluated. Our results showed that addition of Consortium A was effective in reducing the level of contamination of total petroleum hydrocarbons (TPH) from 1086 mg L-1 to 56 mg L-1after just 21 days and to 1...

Currently, petroleum hydrocarbons are the most abundantly used chemicals in the world. Manufactured from crude oil, petroleum hydrocarbons are found in gasoline, kerosene, fuel oil, asphalt, and even some chemicals used in home or at work. Almost every person on this planet has once or more used a petroleum product or byproduct. Due to their wide de mand, they are transported all over the world...

Leakages of oil products derived from petroleum can affect the environment, even causing risks to human. In order to study all the substances that usually are found in a petroleum leakage, it becomes interesting to apply the study to the Total Petroleum Hydrocarbons (TPH) fractions which have similar physico-chemical properties. The purpose of this paper is to perform a suitable risk specific s...

Genotoxic responses towards chronic exposure of Chaetoceros tenuissimus and Skeletonema costatum to water accommodated fraction of petroleum hydrocarbons (WAF-P) were evaluated as biomarkers of petroleum hydrocarbons pollution. The DNA damage caused by water accommodated fraction of petroleum hydrocarbons was assessed in terms of the DNA integrity measured by alkaline unwinding assay. The compa...

The purpose of this study was to investigate the effect of phytoremediation on soils contaminated with heavy crude oil using plants infected by mycorrhizal fungi. Five plant species, Vetiveria zizanioides, Bidens pilosa, Chloris barbata, Eleusine indica, and Imperata cylindrica, infected with the species of mycorrhizal fungi Glomus mosseae, were selected for this study. The degradation of total...

Major degraders of petroleum hydrocarbons in tropical seas have been indicated only by laboratory culturing and never through observing the bacterial community structure in actual environments. To demonstrate the major degraders of petroleum hydrocarbons spilt in actual tropical seas, indigenous bacterial community in seawater at Sentosa (close to a port) and East Coast Park (far from a port) i...

The sediment concentrations of total petroleum hydrocarbons (TPHs), polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), Pb and (207/206)Pb isotope ratios were measured in seven cores from the middle Clyde estuary (Scotland, UK) with an aim of tracking the late Anthropocene. Concentrations of TPHs ranged from 34 to 4386 mg kg(-1), total PAHs from 19 to 16,163 μg kg(-1) and total ...
