“…Katsumata et al [35] also found that a large quantity of DEHP was adsorbed on the inner surface of the chamber, and the emission rate at a temperature of 40°C was about 3-11 times that at 28°C. Similarly, Fujii et al [36] found that the emission rates of di-ethyl phthalate (DEP), DBP and DEHP at 80°C were from several times to a few hundred times greater than that at 20°C for the three plastic materials: synthetic leather, wallpaper and vinyl flooring.…”

Indoor SVOC pollution in China: A review

Epidemiological and toxicological studies have proved that semi-volatile organic compounds (SVOCs) may have significant adverse effects on human health. For example, phthalic acid esters (PAEs), polybrominated diphenyl ethers (PBDEs) and polycyclic aromatic hydrocarbons (PAHs) may harm the endocrine, reproductive and respiratory systems of humans. Moreover, some SVOCs are carcinogenic. This paper summarizes the source emission characteristics for typical SVOCs observed indoors, evaluates the gas-phase and particle-phase concentrations of indoor di-2-ethylhexyl phthalate (DEHP) under the steady-state condition, estimates the exposure of PAEs and the health risk of PAHs, and then proposes some solutions to some urgent problems for indoor SVOC pollution. The results show that the production and consumption quantities of plasticizers, coal and cigarettes in China are the highest in the world, and that the consumption of flame retardants and pesticides are also very high. As estimated, indoor plasticizer and flame retardant concentrations are higher in China than that of the developed countries such as the USA, which implies that indoor SVOC pollution may be more serious in China. According to the model analysis, DEHP remains mainly in the particle-phase under the steady-state condition; the particle-phase concentration of DEHP increases with increasing particle concentration. The exposure of DEHP is higher for children than it is for adults. It is estimated that 260 thousand people are diagnosed with cancer resulting from exposure to PAHs every year. A multidisciplinary approach to the further study of indoor SVOC pollution is necessary. indoor air quality (IAQ), SVOC, plasticizer, flame retardant, health risk Citation: Wang L X, Zhao B, Liu C, et al.

Cotton and polyester, physically and chemically different fabrics, were characterized for sorption of gas-phase polybrominated diphenyl ethers (PBDEs). Scanning electron microscopic (SEM) images and BET specific surface area (BET-SSA) analysis showed cotton's high microsurface area; NMR analysis showed richness of hexose- and aromatic-carbon in cotton and polyester, respectively. Cotton and polyester sorbed similar concentrations of gas-phase PBDEs in chamber studies, when normalized to planar surface area. However, polyester concentrations were 20-50 times greater than cotton when normalized to BET-SSA, greater than the 10 times difference in BET-SSA. The difference in sorption between cotton and polyester is hypothesized to be due to 'dilution' due to cotton's large BET-SSA and/or greater affinity of PBDEs for aromatic-rich polyester. Similar fabric-air area normalized distribution coefficients (K'D, 10(3) to 10(4)m) for cotton and polyester support air-side controlled uptake under non-equilibrium conditions. K'D values imply that 1m(2) of cotton or polyester fabrics would sorb gas-phase PBDEs present in 10(3) to 10(4)m(3) of equivalent air volume at room temperature over one week, assuming similar air flow conditions. Sorption of PBDEs to fabrics has implications for their fate indoors and human exposure.

“…Some prior studies show that temperature may exert a large influence on the concentrations of SVOCs in indoor environments. Theory as well as laboratory‐controlled studies predict increased emissions from indoor sources (eg, building materials) to indoor air at elevated temperatures . In addition, model simulation and chamber studies on specific SVOCs have shown that enhanced particle mass loading could facilitate partitioning of gaseous SVOCs in airborne particles, thus altering the SVOC distribution and exposure .…”

Sources and dynamics of semivolatile organic compounds in a single‐family residence in northern California

Semivolatile organic compounds (SVOCs) emitted from building materials, consumer products, and occupant activities alter the composition of air in residences where people spend most of their time. Exposures to specific SVOCs potentially pose risks to human health. However, little is known about the chemical complexity, total burden, and dynamic behavior of SVOCs in residential environments. Furthermore, little is known about the influence of human occupancy on the emissions and fates of SVOCs in residential air. Here, we present the first‐ever hourly measurements of airborne SVOCs in a residence during normal occupancy. We employ state‐of‐the‐art semivolatile thermal‐desorption aerosol gas chromatography (SV‐TAG). Indoor air is shown consistently to contain much higher levels of SVOCs than outdoors, in terms of both abundance and chemical complexity. Time‐series data are characterized by temperature‐dependent elevated background levels for a broad suite of chemicals, underlining the importance of continuous emissions from static indoor sources. Substantial increases in SVOC concentrations were associated with episodic occupant activities, especially cooking and cleaning. The number of occupants within the residence showed little influence on the total airborne SVOC concentration. Enhanced ventilation was effective in reducing SVOCs in indoor air, but only temporarily; SVOCs recovered to previous levels within hours.
