Determination of sensitivity limit in quantative analysis of polycyclic aromatic hydrocarbons by Gc-ms [PDF]
Acta Periodica Technologica, 2004 The limit of detection (LOD) and the limit of quantitation (LOQ) for 16 individual PAHs from the Environmental Protection Agency (EPA) list (naphthalene, acenaphthylene, acenaphtene, fluorene, phenanthrene antrachene, fluoranthene, pyrene, benzo(a ...

Chlorophyll fluorescence as an indicator of fluoranthene phototoxicity
Plant, Soil and Environment, 2007 The effect of the short-time exposure (12, 24 and 48 h) of increasing concentration (0.1, 1 and 10 mg/l) of intact (FLT) and photo-modified (phFLT) fluoranthene on the chlorophyll fluorescence parameters (F0, FV/FM and ΦII) in pea plants (Pisum sativum L.

Identification of sources of elevated concentrations of polycyclic aromatic hydrocarbons in an industrial area in Tianjin, China [PDF]
, 2009 The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined by gas chromatography equipped with a mass spectrometry detector in 105 topsoil samples from an industrial area around Bohai Bay, Tianjin in the North of China.

Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.

Environmental Toxicology, EarlyView.ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.
