Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Laboratory Development of a Passive Sampling Device for Hydrazines in Ambient Air written by P. A. Taffe and published by . This book was released on 1990 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book Passive Sampling Techniques in Environmental Monitoring written by Richard Greenwood and published by Elsevier. This book was released on 2007-07-03 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring pollutants in air, soil and water is a routine requirement in the workplace, and in the wider environment. Passive samplers can provide a representative picture of levels of pollutants over a period of time from days to months by measuring the average concentrations to which they have been exposed. Air monitors are widely used, for instance to measure the exposure of workers to volatile compounds, but also for monitoring the fate of pollutants in the atmosphere. Passive sampling devices are now becomining increasingly used to monitor pollutants in rivers, coastal waters and ground water where contamination results from sources such as domestic and industrial discharges, and the use of agrochemicals. Passive Sampling Techniques in Environmental Monitoring provides a timely collection of information on a set of techniques that help monitor the quality of air, surface and ground waters. Passive sampling can provide an inexpensive means of obtaining a representative picture of quality over a period of time, even where levels of pollutants fluctuate due to discontinuous discharges or seasonal application of chemicals such as pesticides. Recent changes in legislation have increased the pressure to obtain better information than that provided by classical infrequent spot sampling.Brought together in one source, this book looks at the performance of a range of devices for the passive sampling of metals, and of non-polar and polar organic chemicals in air and in water. The strengths and weaknesses and the range of applicability of the technology are considered.* Comprehensive review of passive sampling - covering air, water and majority of available technologies in one volume* Chapters written by international specialist experts * Covers theory and applications, providing background information and guidelines for use in the field

Download or read book Monitoring Ambient Air Quality for Health Impact Assessment written by World Health Organization. Regional Office for Europe and published by WHO Regional Office Europe. This book was released on 1999 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to the principles and methods of air quality assessment aimed at measuring population exposure to ambient air pollutants and estimating the effects on health. Addressed to policy-makers as well as scientists engaged in air quality monitoring, the book responds to the failure of most monitoring systems to provide data that are useful in estimating and managing threats to health. The need for exposure data on populations at special risk is also addressed. Throughout, emphasis is placed on methods of monitoring and modelling that are cost-effective, targeted, and appropriate to local and national conditions. The report has six chapters. The first introduces WHO activities related to air quality management and explains the need for monitoring systems capable of assessing health impact. The types of information required for health impact assessment are described in chapter two, which outlines several methods of monitoring and modelling that can be used to measure the level and distribution of exposure to air pollutants in populations, identify population groups with high exposure, and estimate adverse effects on health. Chapter three formulates a general concept of air quality assessment, offering advice on principles for designing a monitoring network, interpreting and reporting data, and solving problems with quality assurance. Also included is a comparison of the advantages, disadvantages, and costs of different methods for air quality monitoring. Against this background, the fourth and most extensive chapter describes specific methods for the monitoring of carbon monoxide, ozone, sulfur dioxide, nitrogen dioxide, particulate matter, benzene, polycyclic aromatic hydrocarbons, lead, and atmospheric cadmium. Monitoring strategies for each pollutant are presented according to a standard format, which covers health effects, sources and exposure patterns, monitoring methods, recommended strategies for monitoring and assessment, and a practical example. The remaining chapters offer advice on the collation, analysis, interpretation, and dissemination of data, and summarize the main conclusions and recommendations of the report. Detailed technical guidelines for the use of various methods and models are provided in a series of annexes. The report also reproduces the newly revised WHO air quality guidelines for Europe.

Book excerpt: Passive sampling devices have been used for decades to measure complex mixtures of bioavailable organic chemicals in a variety of environmental media. More recently passive sampler applications have expanded beyond monitoring chemical concentrations, and this dissertation continues to advance methods of passive sampling on many fronts. Despite their growing use, no practical, evidence-based guidelines exist to ensure concentrations of chemicals sequestered in passive samplers are stable in transport and storage. We demonstrated that concentrations of semivolatile chemicals sequestered within passive samplers would be stable with low-cost shipping from isolated locales by simulating in the laboratory a worst-case scenario at 35 °C for two weeks. Quantitative measures of the flux of semivolatile chemicals between soil and air have been limited by the challenges of collecting soil and estimating chemical fugacity from soil. We avoided these pitfalls by adapting passive sampling equipment to directly sample gas-phase chemicals in air above the soil. The sensitivity of the novel technique was demonstrated at three disparate sites, where volatilization was measured at a site with historically contaminated soil, and deposition was measured at another site with a recent oil spill and fire. In a related study, we deployed the same equipment on artificial turf fields to provide the first quantitative measure of semivolatile flux between artificial turf and overlying air. We detected an additional 26 compounds that have not been previously associated with artificial turf, including some that have known human health impacts. Finally, passive sampling principles were applied to measure chemicals in the human personal environment, using a newly-developed silicone passive sampler wristband. Nineteen pesticides were detected that were not reportedly used among 35 rural farmer participants, demonstrating the utility of the wristband in measuring personal exposures to pesticides. Pesticide concentrations in multiple wristbands, worn by a participant over time, were more similar to each other than to other participants, signifying the uniqueness of personal environments and the importance of taking personalized measurements when assessing risk. The advancements in this dissertation capitalize on the features of passive sampling techniques: easy, yet robust, transport capabilities were demonstrated to provide evidence-based transport criteria; ability to directly measure gas-phase chemicals led to quantitative flux measurements from soil and artificial turf; non-selective organic chemical sequestration allowed for identification of unexpected, or previously unreported chemicals; and the polymer qualities that mimic biological membranes sampled the bioavailable fraction for comparing human exposures. The advancements herein provide logistical solutions and sensitive measures of chemical transport and human exposures, and contribute to the expanding range of possibilities for passive sampling.
