The intensive production of fossil fuels has led to serious polycyclic aromatic hydrocarbon (PAH) contamination in water and soil environments (as PAHs are typical types emerging contaminants). Bio-Fenton, an alternative Fenton oxidation, which generates hydrogen peroxide at a nearly neutral pH condition, could ideally work as pretreatment recalcitrant organics, be combined with the subsequent ...

in this study, the effect of hydrocarbon and rosin ester resins combination on the physical and mechanical properties of thermoplastic road markings were evaluated. at first, two basic thermoplastic road marking formulations based on hydrocarbon and rosin ester resins were prepared. several samples of the blends of two basic formulations for thermoplastic road marking were characterized and com...

BACKGROUND Human epidemiological and animal studies suggest that developmental exposure to contaminants that activate the aryl hydrocarbon receptor (AHR) lead to suppression of immune system function throughout life. The persistence of immune deficiency throughout life suggests that the cellular target of AHR activation is a fetal hematopoietic progenitor or stem cell. OBJECTIVES The aim of t...

Field metabolomics and laboratory assays were used to assess the in situ anaerobic attenuation of hydrocarbons in a contaminated aquifer underlying a former refinery. Benzene, ethylbenzene, 2-methylnaphthalene, 1,2,4- and 1,3,5-trimethylbenzene were targeted as contaminants of greatest regulatory concern (COC) whose intrinsic remediation has been previously reported. Metabolite profiles associa...

contamination of soil and air due to hydrocarbon is a global issue and bioremediation providesprobably the best way to remediate the contaminants. the current study shows the biodegradation of crudeoil, diesel and used engine oil by a newly isolated bacillus cereus strain drdu1 from an automobile engine.hydrocarbon degrading strains were screened on bh (bushnell and haas broth) agar supplemente...

total petroleum hydrocarbon ( tph ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. tph are readily transformed into more hydrophilic metabolites, which are accumulated in bile. thus fish bile can be used as a biomarker of exposure of fish to tph in the marine environment. in this study several stations were se...
