Abstract

"Clothing has been proven to be a significant accumulator of chemicals from the air. Semi-volatile organic compounds (SVOCs) have a high affinity towards textiles, and measuring the equilibrium partition coefficient between cloth and air (Kcloth-air) for SVOCs is crucial in predicting human exposure to these compounds. This study aims to quantify Kcloth-air for oxybenzone to contribute to a larger human exposure experiment carried out at the Technical University of Denmark (DTU). Kcloth-air for oxybenzone was calculated using data collected from the exposure chamber at DTU and from performing extractions of oxybenzone in fabric samples from the experiment using HPLC. Kcloth-air was calculated to be 5.9 ± 2.1 x 106 (µg/m3 per µg/m3) for oxybenzone in cotton. Additionally, a lab scale measurement of this partition coefficient at 31 ⁰C was also performed using headspace solid-phase microextraction (SPME). A comparison of the DTU fabric and a similar fabric using the headspace method resulted in Kcloth-air values that ranged over an order of magnitude. The headspace SPME method for measuring Kcloth-air seems promising, but improvements are necessary"--Abstract, page iii.
