As we spend around 90% of our time indoors, and inhale more than half of the body’s air intake during a lifetime while at home, the quality of indoor air is important for our wellbeing. Unlike controllable health factors, such as diet and exercise, the quality of the air we breathe is not entirely a personal choice that can be made, as we are obliged to inhale whatever is around us. Ensuring our indoor environments do not contain harmful pollutants, at least at dangerous levels, is therefore a necessity.
My research focuses on the source of indoor volatile organic compounds (VOCs), mainly consumer products, and the large contribution of solvents. Using Selected-Ion Flow-Tube Mass Spectrometry (SIFT-MS), Quadrupole-Time of Flight Gas Chromatography/Mass Spectrometry (Q-TOF GC/MS), and an in-house built applicant respiration replica I am able to identify and quantify VOC emissions from consumer products and replicate real-life use to evaluate the resulting inhalation risks.
The technique for estimating inhaled dose from consumer products is constantly being developed. As such, updated datasets which supersede that published in Inhalation of VOCs from facial moisturizers and the influence of dose proximity. Indoor Air. 2022; 32(1) are available.
