Silicone wristbands detect individuals' pesticide exposures in West Africa

Wristbands detected between 2 and 10 pesticides per person with novel sampling devices worn by 35 participants who were actively engaged in farming in Diender, Senegal. Participants were recruited to wear silicone wristbands for each of two separate periods of up to 5 days. Pesticide exposure profiles were highly individualized with only limited associations with demographic data. Using a 63-pesticide dual-column gas chromatography–electron capture detector (GC-ECD) method, we detected pyrethoid insecticides most frequently, followed by organophosphate pesticides which have been linked to adverse health outcomes. This work provides the first report of individualized exposure profiles among smallholder farmers in West Africa, where logistical and practical constraints have prevented the use of more traditional approaches to exposure assessment in the past. The wristbands and associated analytical method enabled detection of a broad range of agricultural, domestic, legacy and current-use pesticides, including esfenvalerate, cypermethrin, lindane, DDT and chlorpyrifos. Participants reported the use of 13 pesticide active ingredients while wearing wristbands. All six of the pesticides that were both reportedly used and included in the analytical method were detected in at least one wristband. An additional 19 pesticide compounds were detected beyond those that were reported to be in use, highlighting the importance of measuring exposure in addition to collecting surveys and self-reported use records. The wristband method is a candidate for more widespread use in pesticide exposure and health monitoring, and in the development of evidence-based policies for human health protection in an area where food security concerns are likely to intensify agricultural production and pesticide use in the near future.

Measuring Personal Exposure to Organophosphate Flame Retardants Using Silicone Wristbands and Hand Wipes

Organophosphate flame retardants (PFRs) are widely used as replacements for polybrominated diphenyl ethers in consumer products. With high detection in indoor environments and increasing toxicological evidence suggesting a potential for adverse health effects, there is a growing need for reliable exposure metrics to examine individual exposures to PFRs. Silicone wristbands have been used as passive air samplers for quantifying exposure in the general population and occupational exposure to polycyclic aromatic hydrocarbons. Here we investigated the utility of silicone wristbands in measuring exposure and internal dose of PFRs through measurement of urinary metabolite concentrations. Wristbands were also compared to hand wipes as metrics of exposure. ... Correlations between TDCIPP and TCIPP and their corresponding urinary metabolites were highly significant on the wristbands (rs = 0.5–0.65, p < 0.001), which suggest that wristbands can serve as strong predictors of cumulative, 5-day exposure and may be an improved metric compared to hand wipes.

A simple way to track your everyday exposure to chemicals

Silicone wristbands mimic how the body absorbs toxic compounds

For one week, 92 preschool-aged children in Oregon sported colorful silicone wristbands provided by researchers from Oregon State University. The children’s parents then returned the bands, which the researchers analyzed to determine whether the youngsters had been exposed to flame retardants. The scientists were surprised to find that the kids were exposed to many polybrominated diphenyl ethers (PBDEs), chemicals that are no longer produced in the U.S., as well as to organophosphate flame retardants, which are widely used as substitutes for PBDEs.




Using silicone wristbands to evaluate preschool children's exposure to flame retardants

Published in"Environmental Research" journal, accepted Feb 25, 2016, a new published report on the use of Wristbands as passive sampling devices.


• Silicone wristbands are a non-invasive approach for personal sampling of chemical mixtures.

• Flame retardants were stable in a simulation of transport and storage stability in wristband samplers.

• A total of 20 flame retardants were detected in silicone wristbands worn by children.

• Some flame retardants measured in wristbands were associated with house age, vacuum frequency, and family context.

USA Today:  Worried about toxic chemicals? This band exposes them


USA Today: Worried about toxic chemicals? This band exposes them

During a single week back in August in which I bopped in and around New York City, I was exposed to at least 16 hazardous chemicals. These included phthalate chemicals of the type banned in kids toys and pacifiers, flame retardants such as TCPP and TPP, and Galaxolide, a common fragrance found in cleaning and beauty products.

I’m aware of the sobering details because of a wearable.



FastCompany / FastCoExist Announces MyExposome Wristband

This Wristband Will Tell You Which Chemicals You're Exposed To Every Day

We live in a pretty toxic world. How toxic? This new wearable will let you know—and you probably won't like the results.


We tend to blame bad genes for breast cancer and Alzheimer's, but few diseases are purely genetic. The "exposome"—all the things we're exposed to throughout our lives—often plays a bigger role than DNA. That includes the obvious, like diet and exercise, but also factors that are harder to track, like the chemicals that surround us.

A new wearable called MyExposome is designed to reveal which chemicals are actually part of your everyday life. Strap on the wristband for a week, and it absorbs chemicals—from pesticides to flame retardants—along with you. At the end of the week, you mail it back to a lab to learn about the invisible part of your world.



PR Press Release: MyExposome Announces Wristband

Breathe in, Breathe out. Wash your hair and take a walk outside. With every breath or step you take you are exposed to your environment—to the chemicals around you. Have you ever wondered which chemicals you are exposed to in your everyday life? Until today, you couldn’t measure your personal exposure to those invisible chemicals.

MyExposome ( has designed a new patent-pending technology,  originally developed at Oregon State University, which answers your critical questions about the chemicals in your environment. 


Senator Merkley (Oregon) reveals results of MyExposome Wristband Project


Senator Merkley (Oregon) reveals results of MyExposome Wristband Project

Today Senator Merkley (Oregon) released the preliminary results of a study using the MyExposome wristband (funded by the Environmental Defense fund).   While not directly part of our Kickstarter, ( )  this use of the basic wristband technology demonstrates the core science is strong.    Now the key is to show we can make this available to the general public and enable citizen scientists to gather their own information on environmental exposures..  Or find ways to partner with institutions or researchers or educators....

Anyway... Click to see the full press release or just read this key quote :  “The results of this innovative project show that this isn’t a simple case of being a smart consumer and buying the right products,” said Merkley. “Every wristband showed exposure to toxic chemicals that could have drastic effects on the health of Americans, especially our children. It’s clear from this experiment that we need to take action on every level, in Congress and in our states.”



Kickstarter: Make the invisible, visible! Personal Environmental Monitor!

Today MyExposome announced the launch of their Kickstarter project to let individuals monitor their chemical exposure by simply wearing a silicone wristband. MyExposome has designed a new patent-pending technology, originally developed at Oregon State University, which answers critical questions about the chemicals in an individual’s environment.  MyExposome KickStarter will provide light-weight non-intrusive wristbands that track individual exposure to chemicals in your daily life.   

The monitors are surprisingly simple: silicone wristbands, such as the ones worn in support of various causes, are specially prepared to act as a sponge to absorb hundreds of different chemicals in our environment—the air, water, and even personal care products. The Kickstarter team will then uses multi-million dollar state-of–the-art technology to analyze each wristband to determine exposure to over 1400 chemicals.

 “We realized that if we could harness the power of social media to connect with people who really wanted to know what chemicals they were exposed to we could get a big enough group of individuals together to make it economically viable to do all these tests,” says Marc Epstein, CEO, MyExposome. “Right now the scientific community is using this technology to monitor chemical exposure in segmented groups. We wanted to bring this cutting edge technology to the individual—to make the invisible visible. We hope that this Kickstarter campaign will help people have the information needed to take charge of their own environment.”

Center for Disease Control (CDC): What is the exposome?

Success in mapping the human genome has fostered the complementary concept of the "exposome". The exposome can be defined as the measure of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual’s exposure begins before birth and includes insults from environmental and occupational sources. Understanding how exposures from our environment, diet, lifestyle, etc. interact with our own unique characteristics such as genetics, physiology, and epigenetics impact our health is how the exposome will be articulated.

Silicone wristbands facilitate exposome study

As the environmental health science field strives to better understand the complexity of personal chemical exposures, NIEHS-funded researchers at the Oregon State University (OSU) Superfund Research Program (SRP)  led by Kim Anderson, Ph.D., have developed a simple wristband and extraction method that can test exposure to 1,200 chemicals.
