  • PAHs in Parking Lot Sealcoats - Case Study

    There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff.  Sample was collected from a freshly treated parking lot in Seabrook, New Hampshire. The ...

  • Case study - Performance testing PAHs in asphalt in France

    ESITC – France: New regulations across Europe are requiring laboratory analysis for PAH content in asphalt. Researchers at ESITC’s lab are using the Sitelab TD-500D analyzer to monitor PAH levels in new, reclaimed and recycled asphalt. Maximum PAH limit for reuse is 50 ppm. In this study, three asphalt samples were ground down to different particle sizes and sent to four certified ...

  • Labile, dissolved and particulate PAHs and trace metals in wastewater: passive sampling, occurrence, partitioning in treatment plants

    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 system by means of grab sampling. ...

  • Trace Analysis of PAHs using EPA methods 3541, 3545 and 8100

    The Extraction System B-811 and the Syncore Analyst parallel concentrator from Buchi as well as the Pressurized Solvent Extractor from Applied Separations were evaluated for the pretreatment of samples containing PAHs. Recoveries of extraction and subsequent concentration using acetone-n-hexane (1+1) were 70-95% for 2 ring and 90-100% for less volatile 3-5 ring PAHs. A good precision (95% ...

  • Extraction of Sediment using the SpeedExtractor E-916 for the Determination of Polycyclic Aromatic Hydrocarbons (PAH)

    Polycyclic aromatic hydrocarbons (PAH) are chemical compounds that consist of fused aromatic rings and do not contain heteroatoms or carry substituents. They are of concern because some compounds have been identified as carcinogenic, mutagenic and teratogenic. Sediment samples origin from a round robin program (SETOC 2008/4, Wepal, Wageningen University) were extracted according to EPA 3545A with ...
