Using Silicone Wristbands to Measure Air Quality
The inexpensive, convenient devices can measure exposure to a class of chemicals that can
be harmful during pregnancy.
Texas A&M University, College Station
I
nexpensive and convenient devices
such as silicone wristbands can be used
to yield quantitative air quality data,
which is particularly appealing for periods
of susceptibility such as pregnancy.
The wristbands, when used as passive
samplers, have the ability to bind smaller
molecular weight semi-volatile polycyclic
aromatic hydrocarbons (PAHs) - a class
of chemicals that occurs naturally in
coal, crude oil, and gasoline and are produced
when coal, oil, gas, wood, garbage,
and tobacco are burned - in a similar
pattern as active sampling.
A study was conducted to quantify
maternal PAH exposure in pregnant
women. To gather the data, participants
carried backpacks containing air-sampling
equipment. A silicone wristband
was also attached to each backpack. After
three non-consecutive 24-hour periods,
the air-sampling equipment and wristbands
were analyzed for PAHs.
When the researchers analyzed and
compared the data from the air-sampling
equipment and the wristbands, they
found that the wristbands yielded similar
results to the more traditional testing
methods. The use of the silicone wristbands
as a passive sampler could be useful
in studies of semi-volatile PAHs.
Wristbands have been used to detect a
number of pollutants but qualification of
those pollutants remains a challenge.
The team found that patterns of detection
are similar for low-molecular-weight
compounds and that attaching the wristbands
to the backpack's strap is a good
sampling design for evaluating conditions
under which wristbands could be
used for quantifying PAHs in air.
The results of the study support that
wristbands used as passive samplers may
be helpful in future studies evaluating
adverse health outcomes from prenatal
PAH exposure.
