Determination of particle-associated polycyclic aromatic hydrocarbons in urban air of Beijing by GC/MS.
Particle-associated polycyclic aromatic hydrocarbons (PAHs) collected in urban air of Beijing were studied using a gas chromatograph mass spectrometer (GC/MS). The average concentration of particle-associated PAHs measured in this work was in the range from 28.53 to 362.15 ng/m3, which suggested a serious pollution level of PAHs in Beijing. The results also showed that the concentration of PAHs...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Industrial Harbor Sediments by GC-MS
Analysis of the 16 polycyclic aromatic hydrocarbons (PAHs) of the US Environmental Protection Agency priority pollutant list was carried out in sediment samples of an industrial port in the southern Kaohsiung Harbor of Taiwan which is supposed to be extensively polluted by industrial wastewater discharges. The determination and quantification of PAHs in sediment samples were performed using gas...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Ambient Urban Air
Polycyclic aromatic hydrocarbons (PAHS) have been determined in the atmosphere of Isfahan, Iran. Airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). Extraction of PAHS from airborne particulate matter has been performed using SFE system and the relationship between the extraction temperature and the recovery of PAHS</su...
متن کاملDetermination of 16 priority polycyclic aromatic hyDrocarbons in bottom seDiments of the Danube estuarine coast by Gc/ms
16 priority polycyclic hydrocarbons were identified and determined quantitatively by gas chromatography-mass spectrometry method in bottom sediments of estuarine coast of Danube. Concentration of the sum of 16 polyarenes in bottom sediments ranged from 329.6 to 1093.3 μg/kg. The total B(a)Peqv, whose values at the stations of sampling ranged from 34.9 to 195.1 μg/kg, was determined to evaluate ...
متن کاملValidation of an Analytical Method for Determination of 13 priority polycyclic aromatic hydrocarbons in mineral water using dispersive liquid-liquid microextraction and GC-MS
Dispersive liquid liquid microextraction (DLLME) combined with gas chromatography–mass spectrometry (GC–MS) was used for the extraction and determination of 13 polycyclic aromatic hydrocarbons (PAHs) in mineral water samples. In this procedure, the suitable combination of extraction solvent (500 µL chloroform) and disperser solvent (1000 µL acetone) were quickly injected into the water sample (...
