IGERT Trainee Advances Knowledge of Human Exposure to Toxic Chemicals in Moth Repellents and Deodorizers
UT-Austin IGERT Trainee Priscilla Guerrero designed and constructed an experimental system to study human exposure to toxic chemicals used in moth repellents
Trainee Priscilla Guerrero of the National Science Foundation’s Integrative Graduate Education and Research Traineeship (IGERT) program in Indoor Environmental Science and Engineering at the University of Texas is completing a novel study of human exposure to toxic chemicals used in moth repellents. She is focusing on the extent to which clothing becomes contaminated by p-dichlorobenzene and naphthalene and how contaminated clothing can lead to elevated inhalation and dermal exposures when worn. Trainee Guerrero designed and constructed an experimental system (image) that includes a 300-L electro-polished stainless steel chamber within which up to 36 clothing fabric specimens can be suspended and exposed to p-DCB and naphthalene at constant gas-phase concentrations of each chemical using a delivery system developed for this study.
