Polycyclic Aromatic Hydrocarbons in a Remote High Mountain Lake Food Web in the Central Pyrenees
Brown trouts (Salmo trutta) from four European high mountain lakes (Norway, the Pyrenees,the Alps and the Tatras) were analyzed for metal and organic pollution, histopathologicalabnormalities and biochemical parameters. Fish from all lakes appeared well nourished withconditioning factors close to unity. Their mean age ranged from 4 to 14 years old inGossenköllesee and Vel’ké...
متن کاملMultimedia Model for Polycyclic Aromatic Hydrocarbons (PAHs) and Nitro-PAHs in Lake Michigan
Polycyclic aromatic hydrocarbon (PAH) contamination in the U.S. Great Lakes has long been of concern, but information regarding the current sources, distribution, and fate of PAH contamination is lacking, and very little information exists for the potentially more toxic nitro-derivatives of PAHs (NPAHs). This study uses fugacity, food web, and Monte Carlo models to examine 16 PAHs and five NPAH...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملSome Bioaccumulation Factors and Biota-sediment Accumulation Factors for Polycyclic Aromatic Hydrocarbons in Lake Trout
Bioaccumulation factors (BAFs) and biota-sediment accumulation factors (BSAFs) for phenanthrene, fluoranthene, pyrene, benz[a]anthracene, and chrysene/triphenylene were calculated using the tissue data of Zabik et al. for Salvelinus namaycush siscowet with a 20.5% lipid content, the water data of Baker and Eisenreich, and the sediment data of Baker and Eisenreich for the Lake Superior ecosystem...
