The PAH concentrations in air were highest in Czech Republic and Slovakia, with about 10 times higher levels in these regions compared to the ambient PAH concentrations in Sweden. The PAH concentrations in air of Austria were found to be higher compared to PAH concentrations in Sweden but lower than Czech Republic and Slovakia. ...
Project reference Project: Pilot project in Umeå city (Sweden) Customer: Umeå county, Sweden Project period 2001-2002 Nature of task: Determination of bioacumulative PAH pollution profile in Tvärån stormwater stream Evaluation of possible non-point sources Summary In this study the 16 EPA PAH compounds were studied. ...
Project reference Project: Pilot project in the Bangkok region of Thailand Project period 2000 Nature of task: investigation of the air pollution and the connection between ambient air and aquatic plant concentrations of PAHs in the Bangkok region of Thailand contribution of traffic to atmospheric and plant concentrations of PAH Summary The individual ...

Radiological testing (alpha, beta, C4 and Tritium), and Chemical sampling (heavy metals, mercury, PAH’s, etc) were carried out by Envirochem and practical advice given on the findings. Project Scope Sampling of the chemical outlet drain required confined space and emergency access training. Access to the sample areas was ...
Data Sources >40 years PAH data. Monitoring data since 1980s in consultant’s databases, including EQuIS. ...
Here we present a comparison of the results of individual analyses of PCBs and PAHs from soil samples with single-quadrupole GC-MS and a triple-quadrupole GC-MS (TQ-GCMS). The use of hydrogen carrier gas is, however, still a work in progress for the multiple reaction monitoring (MRM) optimization for the TQ-GCMS. Sample Preparation Soil ...
A simple and low cost method “indirectly suspended droplet microextraction of water‐miscible organic solvents (ISDME)” by salting‐out effect prior to high performance liquid chromatography and UV detection (HPLC‐UV) was used for the determination of polycyclic aromatic hydrocarbons (PAHs) in different samples. ISDME is a combination of salting‐out extraction ...
Multiple replicates of both unspiked and spiked (20 ng/g with PAHs) oil samples were processed for each SPE cleanup technique. The cleanup procedures are summarized in Tables 1 and 2. ...
Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are of great interest because of their high potential mutagenicity and carcinogenicity. PM 2.5 aerosol campaigns were carried out for four seasons from December 2007 to January 2009 in Xujiahui, Baoshan and Lin’an in Yangtze River Delta Region, China. Nine nitro-PAHs were detected, the average seasonal ...
Contaminants enter marine and estuarine environments and pose a risk to human and ecological health. Recently, passive sampling devices have been utilized to estimate dissolved concentrations of COCs, such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). In the present study, the performance of three common passive samplers was ...
Six sampling events were conducted in the summer and fall of 2009 and 2010. Passive sampling device extracts were analyzed for polycyclic aromatic hydrocarbon (PAH) compounds and screened for 1,201 chemicals of concern using deconvolution‐reporting software. ...
The ecological risks posed by PAHs and several halogenated PAHs in these sediment samples were assessed using two redefined guidelines incorporating the toxic equivalency quotients (TEQs) of individual PAH congeners: TEQs effect range–low and TEQs effect range–median. The authors' results suggested that the PAHs ...
Seven different mixtures of PAHs were tested for additivity at an exposure time of 24 h. Three of the PAH mixtures were also studied at 48 and 72 h of exposure. ...
The leachates from six municipal waste landfills, located in South-eastern Poland, were studied for the presence of major, Persistent Organic Pollutants (POPs) – PAHs, Polychlorinated Dibenzo-p-dioxins (PCDDs)/Polychlorinated Dibenzofurans (PCDFs), Polychlorinated Dibenzothiophenes (PCDTs) and Polybrominated diphenyl ethers (PBDEs). ...
The occurrence and the partitioning of polycyclic aromatic hydrocarbons (PAHs) and seven metals (Al, Cd, Cr, Cu, Ni, Pb and Zn) were investigated in activated sludge wastewater treatment plants by means of passive and active sampling. Concentrations total dissolved and particulate contaminants were determined in wastewater at several points across the treatment ...
