Polynuclear Aromatic Hydrocarbons in Port Valdez Shrimp and Sediment
Polynuclear aromatic hydrocarbons (PAHs) from oil were present in some shrimp from Port Valdez, site of a ballast water treatment facility at the Alyeska Alaska Marine Terminal (AMT). Low-level petrogenic PAH concentrations were generally restricted to shrimp eggs in the vicinity of the AMT and extended along the southern shore of Port Valdez to Anderson Bay. Eggs had greater lipid content than...
متن کاملDegradation of polynuclear aromatic hydrocarbons by two strains of Pseudomonas
The goal of this investigation was to isolate competent polynuclear aromatic hydrocarbons degraders that can utilize polynuclear aromatic hydrocarbons of former industrial sites at McDoel Switchyard in Bloomington, Indiana. Using conventional enrichment method based on soil slurry, we isolated, screened and purified two bacterial species strains PB1 and PB2. Applying the ribotyping technique us...
متن کاملMass Transfer of Polynuclear Aromatic Hydrocarbons from Complex DNAPL Mixtures
Parameters governing the rates of mass transfer of the individual components of four synthetic dense non-aqueous phase liquid (DNAPL) mixtures into the aqueous phase were evaluated. The DNAPL mixtures, composed of toluene and eight polynuclear aromatic hydrocarbons (PAHs), were designed to serve as models for coal tars and creosotes. The reactor employed provided a relatively stable interface b...
متن کاملExposure to PAH compounds among cokery workers in the oil shale industry.
The exposure of Estonian cokery workers to polynuclear aromatic hydrocarbons at an oil shale processing plant was assessed by occupational hygiene and biomonitoring measurements. To assess the external dose of exposure to polynuclear aromatic hydrocarbons, pyrene and benzo[a]pyrene concentrations were measured from the breathing zone of workers during a workshift. Skin contamination with pyrene...
متن کاملAnalysis of Polynuclear Aromatic Hydrocarbons by SPME-GC-FID in Environmental and Tap Waters
Desenvolvimento e validação de um método de micro-extração em fase sólida acoplado à cromatografia gasosa com detector de ionização de chama (SPME-GC-FID) para a monitorização de dezesseis PAHs definidos como poluentes em amostras de água pela US EPA. As melhores condições de extração foram obtidas utilizando uma fibra de PDMS 30 μm, extração direta a 60 oC durante 30 min sob agitação (1500 rpm...
