Abstract The purpose of this study was to evaluate the concentration PAHs and health risk in edible mushrooms using magnetic solid phase extraction (MSPE) gas chromatography/mass spectrometry (GC/MS) method. Based on results, total range from 0.82 6.25 µg/kg (with means 3.85 ± 0.24 µg/kg). In study, acenaphthylene (Ace) had maximum mean level mushroom samples (0.84 0.19 μg/kg) benzo(a)pyrene (B...

Abstract We report an inter-laboratory comparison of analytical laboratories involved in the quantification polycyclic aromatic hydrocarbons (PAHs) collected by sampling organisations from industrial stacks (e.g. waste incinerators). Four reference solutions were prepared containing nominally 10 ng/ml, 50 200 ng/ml and 500 naphthalene, benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k...

ABSTRACT. The aim of this investigation was to assess the presence 16 PAHs (naphthalene, acenaphthylene, acenaphthene, fluorene, anthracene, phenanthrene fluoranthene, benz[a]anthracene, pyrene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, benzo[ghi]perylene, and indeno[1,2,3-cd]pyrene with symbols Nap, Ace, Ane, Flu, Ant, Phe, Flt, BaA, Pyr, Chr...

Distribution ratios and sources of polycyclic aromatic hydrocarbons (PAHs), including Fluoranthene (Flt), Pyrene (Pyr), Benzo(a)pyrene (BaP), Benzo(k)fluoranthene (BkP), Indeno(1,2,3-cd)pyrene (IP), Benzo(ghi)perylene (BgP) in urban surface and subsurface soil collected from Riyadh city, Saudi Arabia was studied. The sum of the six PAHs ranged from 30.5-1016.6 ng g -1 with an average of 286.6 i...

MATERIALS AND METHODS lndeno[1,2,3-cd]pyrene (IP) is a major environmental pollutant which is carcinogenic on mouse skin and in rat lung. Unlike benzo(a)pyrene, IP is a nonaltemant polycyclic aromatic hydro carbon which is devoid of a bay region. IP was mutagenic in Salmonella typhimurium TA100 in the presence of a 9000 x g supernatant from the livers of Aroclor-pretreated rats. Using a similar...

The mudflat area in the southern Iraq is untapped and there are few studies about it, this study attempts to determine concentration of aromatic hydrocarbons (PAHs) region, addition their sources assess quality pollution by PPI. Total ranged between (89.8-21.9) µg/g dw with mean value (44.62) dw, among 16 10 these compounds dominant all station as fallow: Benzo(B) (14.46-4.743) Benzo [G,H,I] wa...

The soluble components of fuel oil are generally assumed to be the fraction that is toxic for organisms living in the water column. We have used a liquid phase bioassay with embryos of sea urchin to assess the toxicity of the water-soluble fraction (elutriate) of the fuel oil spilled when the tanker Prestige sank on 13 November 2002. Two methodologies to obtain elutriates were carried out in or...

Este artigo apresenta os resultados da determinação de 12 hidrocarbonetos policíclicos aromáticos (HPAs) em material particulado atmosférico (MPA) coletado na cidade de Niterói, RJ, Brasil. Amostras quinzenais de MPA foram coletadas durante 24 h, entre junho/2005 e maio/2006, no Campus da Universidade Federal Fluminense, localizado em uma área residencial e comercial no Centro de Niterói. Um am...

The human cell mutagenicity of Los Angeles airborne fine particulate matter is examined via bioassay-directed chemical analysis. A 1993 composite fine particle sample is separated via liquid chromatography into fractions containing organic compounds of varying polarity. Samples are analyzed by the h1A1v2 human cell mutagenicity assay to identify those fractions that contain human cell mutagens ...
