DESCRIPTION;LANGUAGE=en-US:Hi everyone\,\n\nJust a friendly reminder for ou
r SOCAAR Seminar Today at 4PM.\n\n----------------------------\nHi Everyon
e\,\n\nSOCAAR is pleased to announce our next seminar:\n\nTuesday\, March
22\, 2016\n\n4 – 5 PM\n200 College Street\, WB 215\n\n\n\nThe influence
of clothing on exposure to methamphetamine\, phthalates and nicotine\n\n\n
\nGlenn Morrison\n\nProfessor\nCivil\, Architectural and Environmental Eng
ineering\nMissouri University of Science & Technology\n\n\n\nAnalyses of e
xposure to indoor air pollutants focus primarily on inhalation of gases an
d particles. However\, other routes of exposure can become important for l
ower volatility chemicals. In this seminar\, clothing is investigated as a
vehicle for concentrating lower volatility organic species such as metham
phetamine\, phthalates and nicotine\, which can then be taken up by oral o
r dermal routes. Methamphetamine is an example of a highly water (and sali
va) soluble compound that can become highly concentrated in clothing simpl
y by air-to-fabric transfer. Toddlers that mouth fabrics in a house with e
ven very-low concentrations of methamphetamine can ingest a substantial do
se. We also hypothesized that wearing clothing should increase dermal upta
ke if the fabric was first allowed to equilibrate with certain SVOCs prese
nt in indoor air. Simple mass transport models demonstrate that close-fitt
ing clothing would reduce external mass-transport resistance and increase
uptake relative to bare skin. To experimentally assess the effect\, we mea
sured uptake of selected airborne phthalates for an individual wearing cle
an clothes or air-exposed clothes and compared these results with dermal u
ptake for bare-skinned individuals under otherwise identical experimental
conditions. When compared against the average results for bare-skinned par
ticipants\, clean clothes were protective\, whereas clothes exposed to pht
halates dramatically increased dermal uptake of DEP and DnBP. Preliminary
experiments with nicotine also show that clothing is also likely to contri
bute to dermal dose in environments subject to tobacco smoke or vaping.\n\
