Episode Transcript

Speaker 1 (00:09):
Welcome to Sustainability Unveiled, where
we explore how our everydaychoices impact our health and
the planet.
I'm EcoVoice and today we'rediving into a surprising and
concerning topic Wearablefitness devices and their links
to harmful chemicals known asPFAS.
Recent research from theUniversity of Notre Dame reveals

(00:31):
that the very tools we use totrack our health might be posing
significant risks.
Let's break down the findingsand what they mean for you.
What did the study find?
The study published inEnvironmental Science and
Technology Letters tested 22smartwatch bands from various
brands and price points.
Here are the key findings HighPFAS levels in certain bands.

(00:53):
Nine out of the 22 tested bandscontained elevated levels of
PFHXA, a type of PFASCorrelation, with price.
Bands costing over $15 weremore likely to contain higher
PFS levels.
Material matters Fluoroelastomerbands, known for their
durability and resistance tosweat and oils, were significant

(01:16):
contributors to PFAS presence.
Professor Emeritus GrahamPeasley, who led the study,
highlighted the startling levelsof PFHXA found in some bands.
Some samples contained over1,000 parts per billion of PFHXA
, much higher than typicallevels in consumer products.
What are PFS and why are they aconcern?

(01:37):
Pfas, or per andpolyfluoroalkyl substances, have
been used in consumer productssince the 950s for their water
and stain resistant properties,but their nearly indestructible
structure means they persist inthe environment for decades,
earning the nickname foreverchemicals.
The health implications areserious Immunosuppression PFAS

(02:00):
exposure can weaken the immunesystem.
Hormonal disruption thesechemicals interfere with
endocrine function.
Developmental delays, linked topotential delays in children's
development.
Cancer risks Long-term exposureincreases the likelihood of
certain cancers.
Wearable devices pose uniquerisks due to prolonged skin
contact, increasing thelikelihood of dermal absorption.

(02:23):
Additionally, disposal ofPFAS-containing products
contributes to environmentalcontamination, affecting soil
and water systems.
How were these findings made?
Researchers employed advancedtechniques to uncover these
results Particle-inducedgamma-ray emission P-I-G-E.
This method measures totalfluorine content in materials, a

(02:45):
strong indicator of PFS present.
Liquid chromatography, tandemmass spectrometry L-C-M-S-M-S.
This precise techniqueidentifies specific PFS
compounds, like PFHXA, byanalyzing their molecular
signatures.
The study's rigorousmethodology ensured accurate
results, including replicatetesting and validation of

(03:07):
detection limits.
Bands were categorized by price, revealing that higher-priced
bands often contained moresignificant levels of PFAS.
What can consumers do?
While addressing PFAS inconsumer products requires
systemic change, individuals cantake steps to protect

(03:46):
themselves.
Choose safer materials.
Opt for bands made from.
Thank you, transparency.
Support at brands thatprioritize PFS-free innovations
and demand clear labeling ofmaterials.
Test at home Fluorine detectionkits available online can help
identify products with highfluorine levels, a marker for
PFAS.
A call for industry andregulation.
The findings underscore theneed for stronger regulations
and industry innovation.
With one in five Americanswearing fitness trackers or
smartwatches for an average of11 hours daily, the potential

(04:10):
exposure to harmful chemicals issubstantial.
Researchers urge manufacturersto explore alternative materials
that maintain durabilitywithout compromising consumer
health.
Professor Peasley emphasizedthis study is a wake-up call for
more comprehensive testing andregulation.
Manufacturers must prioritizesafer options to protect both

(04:31):
consumers and the environment.
Co-author Heather Whiteheadadded that identifying
alternative materials couldsignificantly reduce exposure
risks while maintaining productfunctionality.
That's it for this episode ofSustainability Unveiled.
Wearable technology hasrevolutionized how we track
health, but it's crucial toensure these tools don't

(04:51):
compromise our well-being.
Stay informed, ask questionsand make choices that prioritize
your health and the planet.
Thanks for tuning in and I'llsee you next time.
