Passive sampling is a popular technology for environmental monitoring, and silicone is an ideal choice for a variety of passive sampling applications. The silicone work described here encompasses laboratory and field studies that demonstrate the use of this polymer in novel environments, for new applications, and for emerging compounds. Unique attributes of silicone polymers make them advantageous for targeting semi-polar contaminants not typically targeted in environmental research. Oxygenated polycyclic hydrocarbons (OPAHs) represent an emerging class of contaminants with chemical properties well suited to silicone passive sampling. The first challenge was to create a robust OPAH analytical method to examine these compounds in silicone, and two independent methods (liquid as well as gas chromatography) were optimized and demonstrated for 24 ketone-containing aromatic hydrocarbons, more than other methods published at that time. An isotopically labeled OPAH was used as an internal standard in contrast to previous methods which used only labeled polycyclic aromatic hydrocarbons (PAHs). The efficacy of each method was further demonstrated by comparing standard addition to internal standard quantitation. Next, OPAHs, PAHs and pesticides were used to compare several silicone materials with low density polyethylene (LDPE) at Portland Harbor Superfund field sites. Target analyte detection, precision, and practical considerations in the field and laboratory were used to evaluate silicone materials. Individual differences between LDPE and the most optimal silicone polymer for OPAHs highlighted the importance of using optimized methods or polymer choice for a particular analyte class. Biggest differences were found for 9-fluorenone, benzanthrone, and 5,12-naphtacenequinone. After this successful polymer comparison, the next study involved a novel application of silicone wristbands as personal passive samplers. Commercially available silicone was modified to serve as personal samplers and tested in both an ambient and occupational settings. Silicone wristbands provided a valuable tool to monitor individual exposures that were time weighted averages of personalized exposure. The ambient study captured 49 individual compounds including PAHs, personal and consumer products, pesticides, phthalates, and as well as other industrial compounds. In the occupational study, roofers working with hot asphalt wore silicone samplers and evidence of both temporal (day versus week deployment, p

"The combination of scientific and institutional integrity represented by this book is unusual. It should be a model for future endeavors to help quantify environmental risk as a basis for good decisionmaking." â€"William D. Ruckelshaus, from the foreword. This volume, prepared under the auspices of the Health Effects Institute, an independent research organization created and funded jointly by the Environmental Protection Agency and the automobile industry, brings together experts on atmospheric exposure and on the biological effects of toxic substances to examine what is knownâ€"and not knownâ€"about the human health risks of automotive emissions.

Download Laboratory Development of a Passive Sampling Device for Hydrazines in Ambient Air Book in PDF, ePub and Kindle
A passive sampling method applicable to personnel and area monitoring has been developed for the quantitation of hydrazine, monomethylhydrazine (MMH), and unsymmetrical dimethylhydrazine (UDMH) in ambient air at the part-per-billion (ppb) level. The method uses a black molded low density polyethylene badge consisting of a diffusion barrier and a citric acid collection medium. It collects samples that can be analyzed by the NIOSH colorimetric method or a coulometric titration procedure. The two millimeter thick diffusion barrier contains 144 one millimeter diameter holes and produces a collection rate for MMH of approximately 27 ml/min. The accuracy of data collected with this badge is within 30% of actual values. The dosimeter has demonstrated accuracy for sampling periods of 15 minutes to 66 hours, when sampling MMH at the threshold limit value (TLV) concentration of 200 ppb. The limits of detection are dictated by the specific analytical method. Coulometric titration will detect exposures of 30 ppb-hours. An evaluation of the effects of face velocity, relative humidity, and potential interferences was conducted. (jes).
