“…This is surprising given that lower polarity PCBs might be expected to have a greater affinity for low‐polarity polyester. For brominated diphenylethers (BDEs) sorbing to cotton and polyester in laboratory chambers, Saini et al observed higher mass‐normalized distribution coefficients for polyester than cotton. However, they noted that these materials may not have been at equilibrium because, in part, there was little difference between distribution coefficients normalized by planar surface area.…”

“…Models that predict the impact of clothing on dermal uptake have been developed but require knowledge of the sorptive capacity of the clothing and its exposure history prior to being worn. Accumulation of organic compounds with clothing fabrics has been quantified using laboratory chambers, inferred from dynamic uptake experiments and from fabrics exposed to air in an office . The latter method best assesses the accumulation under real‐world environmental conditions.…”

Partitioning of PCBs from air to clothing materials in a Danish apartment

et al. 2017

Polychlorinated biphenyl (PCB) contamination of buildings continues to pose an exposure threat, even decades after their application in the form of calks and other building materials. In this research, we investigate the ability of clothing to sorb PCBs from contaminated air and thereby influence exposure. The equilibrium concentration of PCB-28 and PCB-52 was quantified for nine used clothing fabrics exposed for 56 days

“…In addition to the influence of chemical properties of the sorbing chemical and fibers, the physical properties of the fibers can also influence sorption. For example, natural fibers such as cotton (cellulose) and wool (protein) tend to have large and irregular surface areas and a porous structure that favors entrapment of particles compared to synthetically derived and spun fibers such as polyester and rayon (rayon is synthetically spun cellulose) inter alia .…”

“…Saini et al 20 found that gas-phase non-polar polybrominated diphenyl ethers (PBDEs) sorption was similar to cotton and polyester when expressed on a planar surface area basis. From this, they concluded the uptake was air-side limited and not influenced by the chemical characteristics of the fabric polymer.…”

From air to clothing: characterizing the accumulation of semi-volatile organic compounds to fabrics in indoor environments

et al. 2016

Uptake kinetics of semi-volatile organic compounds (SVOCs) present indoors, namely phthalates and halogenated flame retardants (HFRs), were characterized for cellulose-based cotton and rayon fabrics. Cotton and rayon showed similar accumulation of gas- and particle-phase SVOCs, when normalized to planar surface area. Accumulation was 3-10 times greater by rayon than cotton, when normalized to Brunauer-Emmett-Teller (BET) specific surface area which suggests that cotton could have a longer linear uptake phase than rayon. Linear uptake rates of eight consistently detected HFRs over 56 days of 0.35-0.92 m /day.dm planar surface area and mass transfer coefficients of 1.5-3.8 m/h were statistically similar for cotton and rayon and similar to those for uptake to passive air sampling media. These results suggest air-side controlled uptake and that, on average, 2 m of clothing typically worn by a person would sequester the equivalent of the chemical content in 100 m of air per day. Distribution coefficients between fabric and air (K') ranged from 6.5 to 7.7 (log K') and were within the range of partition coefficients measured for selected phthalates as reported in the literature. The distribution coefficients were similar for low molecular weight HFRs, and up to two orders of magnitude lower than the equilibrium partition coefficients estimated using the COSMO-RS model. Based on the COSMO-RS model, time to reach 95% of equilibrium for PBDEs between fabric and gas-phase compounds ranged from 0.1 to >10 years for low to high molecular weight HFRs.

“…Clothes, which often contain skin oil, have been shown to remove significant amounts of O 3 indoors and are important for the uptake of semi-volatile organic compounds (SVOCs), which can be accumulated on and released from clothes [21][22][23][24][25][26] . Measurements have shown that a single soiled t-shirt can account for 70% of the total O 3 removed by a person 27 .…”

The impact of clothing on ozone and squalene ozonolysis products in indoor environments

et al. 2019

Multiphase reactions of ozone with human skin oils impact indoor air quality by depleting ozone and forming semi-volatile organic compounds, which can be respiratory and skin irritants. Here we demonstrate the impact of clothing on indoor air composition and human exposure by integrating indoor chemistry modeling over a wide range of different spatial and temporal scales. Constrained by molecular dynamics simulations that provide key kinetic parameters, the kinetic model reproduces experimental measurements and predicts that squalene could persist in clothing for several hours to over a day depending on ozone concentrations. Soiled clothing protects skin from ozone exposure even with high concentrations, but can enhance concentrations of oxidation products to a ppb level depending on air exchange rates. Computational fluid dynamics simulations reveal that primary products have~1.6-2.0 times higher concentrations in the breathing zone than in bulk room air, while secondary products are distributed more uniformly throughout a room.
