abstract = {A suitably chosen reference material should meet specific criteria like representing one of the compound classes most commonly occurring in indoor materials as well as having optimal long-term stability during storage and transport to its destination point and having a compact size. The described interdisciplinary pilot research was aimed to develop and characterize a polymer-based candidate for the laboratory reference material (LRM) of selected representatives of monoaromatic hydrocarbons (toluene and furfural) and terpenes emissions. Recycled, petroleum-based low-density polyethylene (LDPE) was applied as a matrix and was filled with plant-based wastes, such as apple pomace (AP), sunflower husks (SH), or yerba mate (YM) residues. The performance and suitability of the developed candidate for use as laboratory reference material was analyzed using FT-IR spectroscopy and differential scanning calorimetry (DSC). The migration potential of the representatives of monoaromatic hydrocarbons and terpenes emitted from the developed polymer material was assessed using the stationary emission microchamber system (μ-CTE 250). In the case of candidates for LRM with the addition of YM and AP, a clear relationship was observed between the samples seasoning time in the chamber and the total amount of VOCs released into the gaseous phase, including identified and determined representatives of terpenes. Furthermore, the existence of a clear relationship between the size (intensity) of the emission defined by the calculated summary parameters (TVOCs and sum of terpenes) and the seasoning/conditioning temperature of polymeric materials with bioadditives was observed.},

abstract = {One of the more important classes of potentially toxic indoor air chemicals are the Volatile Organic Compounds (VOCs). However, due to a limited understanding of the relationships between indoor concentrations of individual VOCs and health outcomes, there are currently no universal health-based guideline values for VOCs within Europe including the UK. In this study, a systematic search was conducted designed to capture evidence on concentrations, emissions from indoor sources, and health effects for VOCs measured in European residences. We identified 65 individual VOCs, and the most commonly measured were aromatic hydrocarbons (14 chemicals), alkane hydrocarbons (9), aldehydes (8), aliphatic hydrocarbons (5), terpenes (6), chlorinated hydrocarbons (4), glycol and glycol ethers (3) and esters (2). The pathway of interest was inhalation and 8 individual aromatic hydrocarbons, 7 alkanes and 6 aldehydes were associated with respiratory health effects. Members of the chlorinated hydrocarbon family were associated with cardiovascular neurological and carcinogenic health effects and some were irritants as were esters and terpenes. Eight individual aromatic hydrocarbons, 7 alkanes and 6 aldehydes identified in European residences were associated with respiratory health effects. Of the 65 individual VOCs, 52 were from sources associated with building and construction materials (e.g. brick, wood products, adhesives and materials for flooring installation etc.), 41 were linked with consumer products (passive, electric and combustible air fresheners, hair sprays, deodorants) and 9 VOCs were associated with space heating, which may reflect the relatively small number of studies discussing emissions from this category of sources. A clear decrease in concentrations of formaldehyde was observed over the last few years, whilst acetone was found to be one of the most abundant but underreported species. A new approach based on the operational indoor air quality surveillance will both reveal trends in known VOCs and identify new compounds.},

abstract = {For several years intensive research has been carried out with the aim of developing a database of the types and amounts of pollutants released from indoor materials to the indoor environment. The paper discusses in detail basic problems and challenges encountered when estimating the emissions of chemical compounds released from of indoor materials. Factors affecting the validity of data obtained by using two different types of analytical devices operating in a dynamic mode (the ex-situ methods) or passive mode (the in-situ methods) for collecting the analytes samples from the gaseous phase were discussed. The main advantages and important limitations of specific analytical devices and aspects of the morphology of the studied indoor material that may influence the type and amount of chemical compounds released into the air were also highlighted. Attention has also been drawn to challenges encountered when developing candidate reference materials dedicated for measuring emissions from indoor matrices.},

abstract = {Building envelopes are usually comprised of several layers with different materials, which can significantly affect volatile organic compounds (VOCs) concentrations in indoor environments. These layers may act as source and sink alternatively depending on the different sorption and diffusion potentials. The model proposed here is a single zone one and it considers the different emission properties of building components, namely, the different sorption and diffusion characteristics of the side walls, the floor and the ceiling. In addition, each component comprises of several layers, which represents different construction materials. Two VOCs, ethyl acetate and n-octane, representing polar and nonpolar compounds respectively, are modeled to study the emission profiles in a room with several building materials. The effects of various construction materials, and the different convective mass transfer coefficients between room air and different building components, on the emission characteristics are investigated.},
