  • 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 ...

  • Extraction & Analysis of PAHs in Olive Oil Using SupelMIP SPE – PAHs and GC-MS

    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. As such, they are monitored in both the environment and food ...

  • Temperature effects on bioremediation of PAHs and PCP contaminated South Louisiana soils: a laboratory mesocosm study

    Goal, Scope and Background. Temperature and soil moisture content are important environmental variables in bioremediation technologies.Optimizing these variables in-situ would enhance andmaintain remediation of hazardous wastes during cold winter seasons or in cold regions and may lead to reduced maintenance and/or cost. The effect of elevated temperature and soil moisture on bioremediation ...


  • Monitoring - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects.

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...


  • Guidelines for the use of mosses and soils in monitoring contaminant fallout

    In 1999 Italy’s Environmental Protection Agency (ANPA) published a paper on the methods to be used in the case of mosses and soils. After nearly a decade, a review is advisable. The attached Guidelines take account of numerous experiments in the environmental field and include a short description of bryophyte biology. A great many pollutants are present in our environment. In addition to ...

  • Designing and Implementing Perimeter Air Monitoring Programs

    Perimeter or fenceline ambient air quality and meteorological monitoring programs have become increasingly valuable at hazardous waste, landfill, dredging, ports, and MGP remediation sites. Air quality monitoring programs protect public health and reduce owner liability ...

  • Comparison of Monitoring Approaches for Selected Priority Pollutants in Surface Water

    1 AbstractLaboratories from seven EU Member States under the coordination of the Joint Research Centre and in collaboration with the Provincia di Ferrara participated in a technical on-site project during which sampling and analytical methodologies for chemical monitoring according to proposed WFD provisions have been compared. Laboratories had been invited to take samples from a river according ...


  • Performance of passive samplers for monitoring estuarine water column concentrations: 1. Contaminants of concern

    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 evaluated for sampling PAHs and ...

  • Monitoring exposure of brown bullheads and benthic macroinvertebrates to sediment contaminants in the Ashtabula River before, during, and after remediation

    In 2007, approximately 420,500 cubic meters of contaminated sediment were removed from the Ashtabula River by dredging. The primary objective of this study was to monitor contaminant exposure in fish and macroinvertebrates before, during, and following dredging. This was done by measuring tissue concentrations of polychlorinated biphenyl (PCB) and polycyclic aromatic hydrocarbon (PAH) in brown ...

  • The analysis of polycyclic aromatic hydrocarbons in marine samples

    Polycyclic aromatic hydrocarbons (PAH) have been determined in marine samples for many years, but have only rarely been included in either national or international monitoring programmes. PAH can arise in the environment from natural sources, oil and petroleum products and combustion processes. Although oil spills influence PAH concentrations in local areas, the major sources of PAH are ...
