Chemical & Engineering News: Simple way to track exposure!

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.

Highlights

• 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

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 ( www.myexposome.com) 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

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, ( https://www.kickstarter.com/projects/540997591/know-your-personal-chemical-exposure/ )  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.

Silicone Wristbands as Personal Passive Samplers

Silicone Wristbands as Personal Passive Samplers

Active-sampling approaches are commonly used for personal monitoring, but are limited by energy usage and data that may not represent an individual’s exposure or bioavailable concentrations.  Current passive techniques often involve extensive preparation, or are developed for only a small number of targeted compounds.  In this work, we present a novel application for measuring bioavailable exposure with silicone wristbands as personal passive samplers.  Laboratory methodology affecting pre-cleaning, infusion, and extraction were developed from commercially available silicone, and chromatographic background interference was reduced after solvent cleanup with good extraction efficiency (>96%).  After finalizing laboratory methods, 49 compounds were sequestered during an ambient deployment which encompassed a diverse set of compounds including polycyclic aromatic hydrocarbons (PAHs), consumer products, personal care products, pesticides, phthalates, and other industrial compounds ranging in log Kow from -0.07 (caffeine) to 9.49 (tris(2-ethylhexyl) phosphate).  In two hot asphalt occupational settings, silicone personal samplers sequestered 25 PAHs during 8- and 40-hour exposures, as well as 2 oxygenated-PAHs (benzofluorenone and fluorenone) suggesting temporal sensitivity over a single work day or week (p<0.05, power = 0.85).  Additionally, the amount of PAH sequestered differed between worksites (p<0.05, power = 0.99), suggesting spatial sensitivity using this novel application.

National Institute of Health: "The Exposome"

All of the things we’re exposed to, taken together, make up what’s called the “exposome.” In this podcast, we learn how studying the exposome helps scientists take a holistic look at how environmental exposures can keep us healthy—or make us sick.
