This technique is widely employed for the analysis, remediation, and purification of solids, liquids, and gases. ...
Sitelab Corporation was hired by an environmental contractor to analyze 100 sediment samples collected from a post-dredge area covering a 1 mile stretch of river in Hammond, Indiana. The data was used to determine which of the 25 sample locations would require further ...
PAH monitoring being at the core of Chromatotec’s 2015 R&D strategy, it was an evidence for the group to sponsor the annual edition of ISPAC, which took place in Bordeaux from 13 to 17 September. ...
Consequently, these compounds can be present in dairy products produced from cow’s milk such as cheese and butter. Analysis of these compounds in butter can pose a special challenge due to the high fat content and the lipophilic nature of PAHs. Recovery of the PAHs often results in coextraction of the fatty matrix. In this application, ...
Abstract Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found in the environment. PAHs are monitored by the US Environmental Protection Agency and European Union due to their carcinogenic characteristics. In recent global events, PAHs have been a concern ever since the late 1980’s. QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that ...
The USEPA currently recommends using measurements of 18 parent + 16 groups of alkylated PAHs (PAH‐34) to assess the potential for sediment‐bound PAHs to impact benthic organisms at these sites. ...
Abstract Surface decontamination efficacy determination of DeconGel™ 1101 and 1102 on aluminum, stainless steel, and concrete surfaces contaminated with Motor Oil (polyaromatic hydrocarbons fraction) was performed with LC/MS (Liquid Chromatography/Mass Spectrometry) according to Environmental Protection Agency (EPA) SW-846 Methods: 3500C (sampling), 8321B (analysis), and ...
ABSTRACT Surface decontamination efficacy determination of DeconGelTM 1101 and 1102 on aluminum, stainless steel, and concrete surfaces contaminated with Crude Oil (polyaromatic hydrocarbons fraction) was performed with LC/MS (Liquid Chromatography/Mass Spectrometry) according to Environmental Protection Agency (EPA) SW-846 Methods: 3500C (sampling), 8321B (analysis), and 1654A ...
Sixteen polycyclic aromatic hydrocarbons (PAHs) and ignition loss (IL) were determined. The total PAH contents ranged from 62 to 6,325 ng g−1 with a geometric mean of 484 ng g−1. The IL ranged from 0.8 to 17% with a mean of 6%. The PAH contents were correlated with the IL contents, and the IL contents were dependent on the population density. ...

The polychlorinated biphenyls (PCB) and polyaromatic hydrocarbons (PAH) are among the most commonly analysed compound classes in environmental analysis. This article demonstrates how hydrogen carrier gas can be used in place of helium for GC-MS/MS analysis of these compounds. Analysis of polyaromatic hydrocarbons ...
Experimental The Supelclean EZ-POP NP and two competitor silica gel SPE cartridges were compared in terms of matrix removal and analyte recovery for the extraction of select polycyclic aromatic hydrocarbons (PAHs) from olive oil. Multiple replicates of both unspiked and spiked (20 ng/g with PAHs) oil samples were processed for each SPE cleanup technique. ...
Using polycyclic aromatic hydrocarbons (PAHs) as the target, the authors studied some essential but easy to be ignored factors in the analysis of organic pollutants in trace level and displayed how these factors could affect the accuracy of the analysis. With the method established, this paper explored a study on PAHs in typical ...
Polyaromatic hydrocarbons (PAHs) consist of fused aromatic rings and are formed as a by-product during the combustion of fuels. Seven PAHs in particular are known for their carcinogenic properties: benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, chrysene, dibenz[a,h]anthracene, and indeno[1,2,3-cd]pyrene. ...
The aim of the current study was to explore the role of salinity on the degradation chemistry of crude oil polycyclic aromatic hydrocarbons (PAH) and acute toxicity of the water accommodated fraction (WAF) of the dispersant COREXIT 9500A and chemically dispersed crude oil on a common estuarine fish. ...
The Biological Response Indicator Devices Gauging Environmental Stressors (BRIDGES) is a bioanalytical tool that combines passive sampling with the embryonic zebrafish developmental toxicity bioassay to provide a quantitative measure of the toxicity of bioavailable complex mixtures. Passive sampling devices (PSDs), which sequester and concentrate bioavailable organic contaminants from the ...
Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water is performed with a solvent extraction of the sample matrix and liquid injection into a GC/MS system; a similar technique has been applied to monitoring PAHs adsorbed to the surface of fine particulates in ...
Under the LRTAP Convention, Parties (including the European Union) are obliged to report emissions data for a large number of air pollutants, including nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), sulphur oxides (SOx), ammonia (NH3), carbon monoxide (CO), primary particulate matter (PM2.5 and PM10), and certain heavy metals lead (Pb), cadmium (Cd), mercury (Hg) and ...
Introduction Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants primarily formed by incomplete combustion and incineration. PAHs adsorb strongly to small carbonaceous particles but are also present in the vapor phase. ...

Samples were collected from sandy and rocky sites for gas chromatography in five carbon ranges of gasoline, diesel oil, engine oil, BTEX, and PAH. The GC analysis revealed the highest pollutant concentration levels in autumn and the lowest in summer; moreover in rocky beaches analysis indicated that a major portion of the oil pollution in the ...
