“…There is a large increase in concentrations (C) for small variations in the loading rate, especially for small ratios (R). The curves display a typical asymptotic pattern and the points may be fitted to a simple non-linear equation C = a (1 -e -bR ), a relationship also found by other authors [7].…”

Emission of pesticides from treated wood can lead to contamination of the environment through several mechanisms. The main processes governing these emissions are lixiviation and evaporation. Emissions from treated wood into the surrounding air were modelled in this study with a protocol using a glass test chamber. The aims were to identify factors influencing such emissions into indoor air (wood drying period, temperature, loading rate: treated wood surface/room volume in m²·m^–3) in order to predict air concentrations of the pesticides. Emission of pentachlorophenol (PCP), a well known fungicide extensively used in the last two decades for wood preservation, was assessed. This first study was conducted on wood treated with an organic or an aqueous formulation containing respectively PCP or its sodium salt, PCPNa.

“…For this NIST project, only the data published in first degree references (e.g., peer-reviewed journal articles as opposed to conference proceedings) were used. This data subset resulted in over 800 VOC emission rates from 16 references (Brown 1999a;Brown 1999b;Kelly et al 1999;Lundgren et al 1999;Horn et al, 1998;Chang et al 1997;Van der Wal et al 1997;Schaeffer et al 1996;Nagda et al, 1995;Chang and Guo 1994;Hodgson et al 1993;Chang and Guo 1992;Hawkins et al 1992;Colombo et al 1990;Schlitt and Knoppel 1989;Wallace et al 1987).…”

In order to estimate building contaminant concentrations and associated occupant exposures, indoor air quality (IAQ) model users require data related to source strengths and other contaminant transport mechanisms (e.g. sinks, filters). Much of this information exists in the literature; however, it is not readily accessible, thereby requiring users to expend significant efforts in searching for this information. To support the modeling process, the National Institute of Standards and Technology (NIST) has created a series of model input databases for use in its multizone IAQ and ventilation model CONTAM. As part of this effort, a standard data entry format was developed, as well as a computer program to search the database for specific records and build a CONTAM input library. These databases and tools can serve as a basis for building an extensive collection of model input parameters, assessing the quality and completeness of existing data sets, and allow for identification of significant data gaps.

First, in the present study, the double-exponential decay model (similar to that of Colombo et al [22], having four control parameters to be determined) was applied to the long-term emission measurements, defined as follows:…”

This is of importance for the application of the source identification method since materials age over time in real indoor environments. The method is based on the mixed air sample measurements containing pollutants from multiple aged materials and the emission signatures of individual new materials determined by PTR-MS. Three emission decay source models were employed and evaluated for their ability to track the change of individual material emission signatures by PTR-MS over a nine-month period. Nine building material specimens were studied in a ventilated 50-L small-size chamber for their emissions individually for nine months, and also in combination later. Chamber exhaust air was sampled by PTR-MS to construct a temporal profile of emission signature unique to individual product type. The similar process was taken to measure mixture emissions from multiple materials, which is for applying and validating the developed method for source identification enhancement, considering the variation in long-term emission rates of individual VOCs. Results showed that the proposed approach could predict the emission signatures of individual building materials at a later time (9-month) with less than 6% difference variance, and hence indicated the potential of the source identification method for aged materials in real indoor environments.
