“…Laboratory experiments have shown that the genotoxic, mutagenic, and carcinogenic activity depended on the chemical structure of polycyclic aromatic hydrocarbons (PAHs) [1]. As a consequence, 16 PAHs have been included in the list of priority pollutants by the US Environmental Protection Agency (US EPA) [2].…”

Effects of temperature on the reversed-phase chromatographic behavior of PAHs were investigated on three columns. The first was the recent C18column (250 mm × 4.6 mm) packed with 5 µm core-shell particles while the others were more conventional C18columns (250 mm × 4.6 mm) packed with fully porous particles. Among the 16 PAHs studied, special attention has been paid to two pairs of PAHs, fluorene/acenaphthene and chrysene/benzo[a]anthracene, which often present coeluting problems. Due to the low surface area of the core-shell particles, lowest retention time of each PAH was highlighted and effects of the temperature on the separation of PAHs were negligible in regard to those using columns packed with fully porous particles. For each PAH studied, it was demonstrated that peaks were symmetrical and may be considered as Gaussian peaks when the column packed with core-shell particle was employed. In the best condition, the separation of PAHs was conducted at 16°C under very low pressure values (670–950 psi = 46–65 bars). Depending on PAHs, the limit of detection ranged from 0.88 to 9.16 μg L−1. Analysis of spiked acetonitrile samples with PAHs at 10 and 50 µg L−1and tap water at 10 µg L−1gave very good recoveries (94%–109.3%) and high precision (1.1%–3.5%).

“…The former include forest fires and volcanic eruptions, and the latter include industrial processes, use of fuel for residential heating, waste incineration, and motor vehicles (2). Laboratory experiments have clearly shown the carcinogenic and mutagenic activity of these compounds and the dependence of this activity on their chemical structure (3). Consequently, 16 PAHs have been included in the list of priority pollutants, the environmental monitoring of which is of prime importance in safeguarding human health (4,5).…”

“…Volatile organic compounds (VOC) in the ambient air are of concern due to their effects on air pollution such as potential health impact, odorous nuisance, and photochemical smog [1][2][3][4]. Both stack and fugitive emissions from refinery operations release a large quantity of volatile organics into the atmosphere [5][6][7].…”

Airborne concentrations of aromatic volatile organics were measured inside a refinery complex and its vicinity in normal operation and stand-by mode, for which a naphtha plant had been semi-operated for two weeks for repairing the air pollution control devices. The monitoring program was conducted in five different regions: inside the naphtha plant, surroundings of the naphtha plant, inside the refinery complex, on the refinery fenceline, and in the neighborhood of the refinery.Total concentrations of volatile organics within the naphtha plant increased significantly in hot-standby mode due to fugitive emissions. The correlations between airborne concentrations inside the naphtha plant and those outside the refinery complex were not significant. Local traffic emissions, rather than refinery emissions, exhibited significant site-specific effects on ambient aromatic volatile organics.Characteristic ratios of various aromatic volatile organics also varied in different operation modes.
