Webquantification of PAHs in sediment samples were performed using gas chromatography coupled to mass spectrometry (GC-MS) with the aid of deuterated PAH internal standards and surrogate standards. The total concentrations of the 16 PAHs varied from 4,425 to 51,261 ng/g dw, with a mean concentration of 13,196 ng/g dw. The PAHs concentration is WebA polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two …

WebPAHs may be in soil near disposal sites where construction wastes or ash is buried. Due to metabolism of PAHs by vertebrates, there is no significant accumulation of PAHs in fish meat. However, eating shellfish living in contaminated water may be another major source of exposure. Vegetables do not take up significant amounts of PAHs that are in ... Web14 jul. 2024 · PAHs concentrations ranged from 105 to 513 ng g −1 ww and from 53.9 to 401 ng g −1 ww in different tissues of bighead carp and silver carp, respectively. Low molecular weights (LMW) PAHs were the predominant compounds, suggesting the gill-water transfer might be the major exposure route for PAHs in the studied fish species. foam buster wwtp
