Pressurised Liquid Extraction of Polycyclic Aromatic Hydrocarbons from Soil and Sediment Samples
Pressurised liquid extraction (PLE) is essentially an analyteand matrix-independent technique. It provides cleaner extracts than the time-consuming classical procedures. In this study, PLE was miniaturised and performed in a stainless-steel cell of 10 mm x 3 mm I.D. 50 mg amounts of the solid samples were packed in the holder. After being subjected to the PLE procedure, 50 out of 100-μl extract...
متن کاملAtmospheric polycyclic aromatic hydrocarbons in Mumbai, India
Atmospheric particulate PAH concentrations were measured at two locations in Mumbai (formerly Bombay), India. Total PAH concentrations (seven compounds) at Saki Naka and Indian Institute of Technology (IIT) were 38.8 and 24.5 ng m~3. Pyrene and benz(a)anthracene#chrysene were abundant at both sites while benzo(b)#uoranthene and benzo(k)#uoranthene were abundant, in addition, at the IIT site. Th...
متن کاملAtmospheric polycyclic aromatic hydrocarbons: Source attribution, emission factors and regulation
There is an increasing concern about the occurrence of polycyclic aromatic hydrocarbons (PAHs) in the environment as they are ubiquitous in ambient air and some of them are among the strongest known carcinogens. PAHs and their derivatives are produced by the incomplete combustion of organic material arising, partly, from natural combustion such as forest and volcanic eruption, but with the majo...
متن کاملAnalysis of polycyclic aromatic hydrocarbons in atmospheric particulate samples by microwave-assisted extraction and liquid chromatography.
A methodology based on microwave-assisted extraction (MAE) and LC with fluorescence detection (FLD) was investigated for the efficient determination of 15 polycyclic aromatic hydrocarbons (PAHs) regarded as priority pollutants by the US Environmental Protection Agency and dibenzo(a,l)pyrene in atmospheric particulate samples. PAHs were successfully extracted from real outdoor particulate matter...
متن کاملPOLYCYCLIC AROMATIC HYDROCARBONS (PAHs) IN FINE AND COARSE PARTICLES
About 140 samplings of fine and coarse particles were gathered during the year 2006 in Kozani that represent an urban area surrounded by opencast coal mining. A low volume dichotomus sampler has been used to trap suspended particles. The filters used were teflon, which are ideal for analysis in the determination of PAHs. The determination of Polycyclic Aromatic Hydrocarbons (PAHs) has been carr...
