Evaluating cost when selecting performance reference compounds (PRCs) for the environmental deployment of polyethylene passive samplers
A challenge in environmental passive sampling is determining when equilibrium is achieved between the sampler, target contaminants, and environmental phases. A common approach is the use of performance reference compounds (PRCs) to estimate target contaminant sampling rates and indicate degree of sampler equilibrium. One logistical issue associated with using PRCs is their sometimes exorbitant ...

Polybrominated diphenyl ethers, dechlorane plus, and polychlorinated biphenyls in tree bark near the upper Yellow River, China
Willow tree bark samples from urban and rural sites in Inner Mongolia, Ningxia Province, and Gansu Province, in the Yellow River basin, were analyzed for polybrominated diphenyl ethers (PBDEs), dechlorane plus (DP), and dioxin‐like polychlorinated biphenyls (DL‐PCBs) to compare their relative levels in air in these areas (i.e., treating bark as a passive air sampler). No difference was found ...

Measurement of selected polychlorinated biphenyls (PCBs) in water via ultrasound assisted emulsification–microextraction (USAEME) using low-density organic solvents
Despite bans and restrictions for their adverse health effects including endocrine disruption, due to their stability in the environment, polychlorinated biphenyls (PCBs) are still of concern for their residues in several matrices. This study employed low-density ultrasound-assisted emulsification–microextraction (USAEME) to measure selected PCBs (28, 52, 101, 118, 138, 153, and 180) in water ...

GC-MS/MS analysis of PAH and PCB in environmental samples
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 (PAH) is typically conducted using HPLC with UV- and fluorescence detection. ...

Analytical methods for PCBs and organochlorine pesticides in environmental monitoring and surveillance: a critical appraisal
Abstract Analytical methods for the analysis of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) are widely available and are the result of a vast amount of environmental analytical method development and research on persistent organic pollutants (POPs) over the past 30–40 years. This review summarizes procedures and examines new approaches for extraction, isolation, ...

Innovations in Site Characterization. Case Study: Dexsil L2000 PCB/Chloride Analyzer for Drum Surfaces
Executive Summary This case study describes a field analytical method that was used to measure PCB surficial contamination in empty drums to be cleaned by a new process. Approximately 7,000 empty 55-gallon drums that previously contained PCB-contaminated material had accumulated at the Department of Energy (DOE)’s East Tennessee Technology Park in Oak Ridge, TN. Because disposal of these drums ...

Evaluations of Polar and Highly Polar Ionic Liquid Capillary GC Columns with Environmental Samples
Ionic liquids are a class of non-molecular ionic solvents with low melting points. These liquids are unique combinations of cations and anions and can provide a variety of different selectivities when used as stationary phases in capillary gas chromatography. A number of ionic liquid phases have been evaluated and characterized for selectivity and determined to be polar or highly polar in ...

Dialysis with a semipermeable membrane – a new sample-preparation technique for determination of Polybrominated Diphenyl ethers in fatty matrices
Summary Dialysis with a low-density polyethylene semipermeable membrane (SPM) is an efficient means of removal of lipids in the determination of bioaccumulative, persistent, halogenated organic compounds. In this study an SPM was used for preconcentration of polybrominated diphenyl ethers (PBDE) from food samples. The method is useful for determination of PBDE and other halogenated persistent ...

Determination of anthropogenic pedo-geochemical backgrounds (FPGAs): the case of Toulouse Métropole - Case Study
Urban soils hold the "memory" of cities; the geochemical quality of urban soils, to which the population is exposed, reflects its history: emissions since the industrial revolution, successive reconstructions on rubble, particularly following historical conflicts, etc. This is why we know little about the quality of these surface layers, made up of rubble of uncertain composition, even though it ...

Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings
There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...
