Book Synopsis Organic Indoor Air Pollutants by : Tunga Salthammer
Download or read book Organic Indoor Air Pollutants written by Tunga Salthammer and published by John Wiley & Sons. This book was released on 2009-11-18 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the quality of indoor air ranking highly in our lives, this second, completely, revised edition now includes 12 completely new chapters addressing both chemical and analytical aspects of organic pollutants. Sources of indoor air pollutants, measurement and detection as well as evaluation are covered filling the gap in the literature caused by this topical subject. This book is divided into four clearly defined parts: measuring organic indoor pollutants, investigation concepts and quality guidelines, field studies, and emission studies. The authors cover physico-chemical fundamentals of organic pollutants, relevant definitions and terminology, emission sources, sampling techniques and instrumentation, exposure assessment as well as methods for control. Test methods and studies for various indoor environments are described, such as automobile interiors, museum environments, or rooms with air ventilation. Emission sources covered include household and consumer products as well as electronic devices and office equipment. The book is aimed at chemists, physicists, biologists, and medical doctors at universities and research facilities, in industry and environmental laboratories as well as regulative bodies.

Available in PDF, EPUB and Kindle. Book excerpt: Building materials and furnishings emit a wide variety of indoor pollutants, such as volatile organic compounds (VOCs). At present, no accurate models are available to characterize material emissions and sorption under realistic indoor conditions. The objective of this thesis is to fill that gap. Using the emission data measured in small-scale and full-scale environmental chambers, this investigation has developed a numerical model for simulating emissions of "wet" materials applied to porous substrates. This model considers VOC mass transfer processes in the air, material-air interface, material film, and the substrate. The model can predict "wet" material emissions under different environmental conditions (i.e., temperature, velocity, turbulence, and VOC concentration in the air) with reasonable accuracy. We developed two models for simulating VOC emissions from dry materials. One is a numerical model for short-term predictions, the other is an analytical model for long-term predictions. The models have been successfully used to examine the VOC emissions from two particleboard samples and a polypropene Styrene-Butadiene Rubber (SBR) carpet. A VOC sorption model has also been developed to analytically solve the VOC sorption rate as a function of air-phase concentrations. The model has been validated using an analytical solution as well as data obtained from sorption experiments. The emission and sorption models that we developed have been further used to study indoor air quality (IAQ) in a small office with different ventilation systems. The results show that displacement ventilation may not provide better IAQ than mixing systems if the VOC sources are from the floor. Further, our study shows sink effects from internal walls of gypsum board.

Book Synopsis Indoor Air Pollution by : Peter Pluschke
Download or read book Indoor Air Pollution written by Peter Pluschke and published by Springer Science & Business Media. This book was released on 2004-09-27 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indoor Air Pollution has become a major topic in environmental research and health. Most people spend more than 80% of their time in buildings and are exposed to a broad range of pollutants from indoor sources such as building materials, furniture, carpets and textiles, heating and cooking, household and consumer products, etc. The volume provides a comprehensive review of the major indoor air pollutants: volatile organic compounds, biocides, indoor particles and fibres, combustion products and micro-organisms and their metabolites. Sources and sinks of air pollutants in indoor environments and their chemistry are distinctly different from ambient air pollution, even though the latter may influence indoor air quality. Adsorption and desorption processes, the pollutant source dynamics, gas phase reactions and kinetics - including the fate and final chemical destiny of chemically unstable intermediate compounds - are topics of scientific research as well as the evaluation of their sensory impact and irritation potential. Guidelines for assessing indoor pollution and a broad range of analytical methods have been recently developed and are reviewed by internationally renowned scientists. The specific characteristics of indoor air pollution in developing countries due to the widespread use of open fires for cooking, heating and lighting are analysed as well as the Chinese strategies to address the growing pollution problems by air pollution in its modern building stock.

Available in PDF, EPUB and Kindle. Book excerpt: A simple model is proposed to account for observed emissions of volatile organic compounds (VOCs) from new carpets. The model assumes that the VOCs originate predominantly in a uniform slab of polymer backing material. Parameters for the model (the initial concentration of a VOC in the polymer, a diffusion coefficient and an equilibrium polymer/air partition coefficient) are obtained from experimental data produced by a previous chamber study. The diffusion coefficients generally decrease as the molecular weight of the VOCs increase, while the polymer/air partition coefficients generally increase as the vapor pressure of the compounds decrease. In addition, for two of the study carpets that have a styrene-butadiene rubber (SBR) backing, the diffusion and partition coefficients are similar to independently reported values for SBR. The results suggest that predictions of VOCs emissions from new carpets may be possible based solely on a knowledge of the physical properties of the relevant compounds and the carpet backing material. However, a more rigorous validation of the model is desirable.

Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this research, was to measure the emission rates of selected individual VOC, including low molecular-weight aldehydes, released by samples of four new carpets that are typical of the major types of carpets used in residences, schools and offices. The carpet samples were collected directly from the manufacturers' mills and packaged to preserve their chemical integrity. The measurements of the concentrations and emission rates of these compounds were made under simulated indoor conditions in a 20-M3 environmental chamber designed specifically for investigations of VOC. The measurements were conducted over a period of one week following the installation of the carpet samples in the chamber. Duplicate experiments were conducted for one carpet. In addition, the concentrations and emission rates of VOC resulting from the installation of a new carpet in a residence were measured over a period of seven weeks. The stabilities of the week-long ventilation rates and temperatures were one percent relative standard deviation. The four carpets emitted a variety of VOC, 40 of which were positively identified. Eight of these were considered to be dominant. They were (in order of chromatographic retention time) formaldehyde, vinyl acetate, 2,2,4-trimethylpentane (isooctane), 1,2-propanediol (propylene glycol), styrene, 2-ethyl-l-hexanol, 4-phenylcyclohexene (4-PCH), and 2,6 di-tert-butyl-4-methylphenol (BHT). With the exception of formaldehyde, only limited data are available on the toxicity and irritancy of these compounds at low concentrations. Therefore, it is difficult to determine at this time the potential magnitude of the health and comfort effects that may occur among the population from exposures to emissions from new carpets. The concentrations and emission rates of most compounds decreased rapidly over the first 12 h of the experiments.
