DESCRIPTION;LANGUAGE=en-US:Hi Everyone\,\n\nSOCAAR is pleased to announce o
ur next seminar:\n\nTuesday\, March 22\, 2016\n\n4 – 5 PM\n200 College S
treet\, WB 215\n\n\n\nThe influence of clothing on exposure to methampheta
mine\, phthalates and nicotine\n\n\n\nGlenn Morrison\n\nProfessor\nCivil\,
Architectural and Environmental Engineering\nMissouri University of Scien
ce & Technology\n\n\n\nAnalyses of exposure to indoor air pollutants focus
primarily on inhalation of gases and particles. However\, other routes of
exposure can become important for lower volatility chemicals. In this sem
inar\, clothing is investigated as a vehicle for concentrating lower volat
ility organic species such as methamphetamine\, phthalates and nicotine\,
which can then be taken up by oral or dermal routes. Methamphetamine is an
example of a highly water (and saliva) soluble compound that can become h
ighly concentrated in clothing simply by air-to-fabric transfer. Toddlers
that mouth fabrics in a house with even very-low concentrations of methamp
hetamine can ingest a substantial dose. We also hypothesized that wearing
clothing should increase dermal uptake if the fabric was first allowed to
equilibrate with certain SVOCs present in indoor air. Simple mass transpor
t models demonstrate that close-fitting clothing would reduce external mas
s-transport resistance and increase uptake relative to bare skin. To exper
imentally assess the effect\, we measured uptake of selected airborne phth
alates for an individual wearing clean clothes or air-exposed clothes and
compared these results with dermal uptake for bare-skinned individuals und
er otherwise identical experimental conditions. When compared against the
average results for bare-skinned participants\, clean clothes were protect
ive\, whereas clothes exposed to phthalates dramatically increased dermal
uptake of DEP and DnBP. Preliminary experiments with nicotine also show th
at clothing is also likely to contribute to dermal dose in environments su
bject to tobacco smoke or vaping.\n\n\n\n\n\nIf you are unable to join us
