A panel at the latest American Association for the Advancement of Science conference held in Washington D.C. last week revealed some startling new information about the chemicals and particulates found inside homes and their potential to wreak havoc on human bodies, especially small ones.

The studies presented at the session, titled “Homes at the Center of Chemical Exposure: Uniting Chemists, Engineers, and Health Scientists” showed that pollutants can be released into your home by everything from cooking to cleaning to the filler inside your furniture. Some of these chemicals and particulates have been linked to thyroid disorders, respiratory issues, and cancers.

Marina Vance from CU Boulder’s Department of Mechanical Engineering and Visiting Professor Joost de Gouw of the school’s Cooperative Institute for Research in Environmental Sciences (CIRES) spoke about household products and cleaners that emit air pollutants. Their research took place in an uninhabited 1,200-square-foot test home built as part of a collaborative project with the University of Texas Austin.

Vance, who has long been a part of the project, called HOMEChem, used advanced sensors and cameras to monitor the indoor air quality over the course of a month. The scientists conducted daily household activities including cooking and cleaning in the home and measured their effects on air quality. According to Vance, “We wanted to know: How do basic activities like cooking and cleaning change the chemistry of a house?”

Of course, we all live in homes where cooking and cleaning takes place on a daily basis, so what’s the big deal? Well, it turns out the chemical compounds emitted by these activities get into your body from breathing the air, eating the food you produce, and touching your furniture.

The final results of the study are still pending, but allowed the researchers to report that

…routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city.

Even tasks as simple as boiling water over a stovetop flame could contribute to potentially dangerous levels of gaseous air pollutants and suspended particles. “Even the simple act of making toast raised particle levels far higher than expected,” Vance said.

Gouw, also from UC Boulder, pointed out that while we often think about vehicles as a major source of air pollution, clean air advocates have ensured improvements in that area. In the meantime, we’ve seen chemicals used indoors such as cleaners, glues, coatings, and personal care items become a much larger source of volatile organic compounds (or VOCs).

He said while some pollutants (like ozone and fine particulates) are monitored by the EPA:

“…data for airborne toxins like formaldehyde and benzene and compounds like alcohols and ketones that originate from the home are very sparse.”

But it’s not just your cleaning products or your cooking choices that lead to airborne toxins. Heather Stapleton, an environmental chemist at Duke’s Nicholas School of the Environment, also told the audience that her research showed that semi-volatile organic compounds (SVOCs) were commonly found in the bodies of children living in homes with vinyl flooring as well as couches and chairs that contained flame-retardant chemicals.

While the Boulder researchers used their test house to perform reseach at will, Stapleton and her team tested children that were already living in homes with these risk factors.

Despite the fact that SVOCs are widely used in everything from electronics to furniture and “can be detected in nearly all indoor environments,” Stapleton said “there has been little research on the relative contribution of specific products and materials to children’s overall exposure to SVOCs.”

In this project, Stapleton and her colleagues from Duke, the CDC, and Boston University examined 203 children from 190 families between 2014 and 2016 to measure in-home exposure to these chemicals by collecting samples of indoor air, indoor dust, and foam from furniture in each of the children’s homes. They also took a hand wipe sample, urine, and blood from each child.

(Of course, all U.S. researcher who work on humans, and especially on children, are required to have their research approved by an ethics board and provide some sort of resources to families who participate.)

When testing the blood and urine, scientists used 44 biomarkers to see if the samples indicated exposure to toxins. In homes where the living room sofa contained flame retardant materials (specifically flame-retardant polybrominated diphenyl ethers, or PBDEs) children had a six-fold higher concentration of that chemical in their blood. Children from homes that had vinyl flooring in every room (although that was only 9% of homes) were found to have concentrations of a compound called benzyl butyl phthalate (BBP) metabolite in their urine that were 15 times higher than those in children living with no vinyl flooring.

While most of the studies on these chemicals’ role in diseases have not demonstrated a conclusive causal relationship and therefore require more evidence, PBDEs have been linked to neurodevelopmental delays, obesity, endocrine and thyroid disruption, and cancer. BBPs have been linked to respiratory disorders, skin irritations, multiple myeloma, and reproductive disorders.

“There was originally skepticism about whether or not these products actually contributed to air pollution in a meaningful way, but no longer,” de Gouw said. He continued:

“Moving forward, we need to re-focus research efforts on these sources and give them the same attention we have given to fossil fuels. The picture that we have in our heads about the atmosphere should now include a house.”

While neither Stapleton nor Vance could be reached for comment on steps we can take to prevent harm done by poor indoor air quality, the World Health Organization has long recognized the dangers of this pollution, especially on children, and recommended good ventilation while cooking, the use of lids on pots and pans, cleaning cooking areas, and keeping children away from smoke to protect them.

But the research also leaves us wondering how to maintain our lifestyles and keep a clean home if even cleaning products can have deleterious effects on health. It’s difficult to crack a window in the winter or in an area where outdoor pollution is also a problem. Children touch things all the time in stores, schools, and other people’s homes that we have no control over. Asking people to replace their vinyl flooring or purchase a couch without flame retardant materials isn’t always economically viable.

The Asthma and Allergy Foundation of America lists even more sources of household pollutants that can affect air quality. While they include a long list of things we can do to improve that quality (but note that this information is sponsored by Dyson), taking all of the recommended steps could seem overwhelming, and the furniture guidelines could require large investments (for example, discarding throw pillows, using only washable curtains, purchasing leather or vinyl sofas and chairs, and replacing carpets with low-VOC flooring, etc.).

However, some of the steps recommended by agencies across the world can provide a useful start on getting into new behaviors, including paying attention to the materials any new home items you purchase are made of. Next time you purchase cleaning supplies, you can get unscented and non-aerosol versions. And you can air out your home when the weather (and other conditions) permit. Sadly, you’ll probably want to remove candles and air fresheners from your home if allergies and asthma are potential problems. And when you have the money, you can also invest in air filters, especially for areas where pets and children spend time.

Unfortunately, manufacturers are not currently obligated by U.S. law to list all ingredients in consumer products and labels such as “natural” or “green” do not necessarily mean the products are safer. Better air quality will require some research on your part, and it’s best to find a reliable source of information(not a manufacturer’s website, which is devoted to marketing their products to you). One place to start is the EPA’s Safer Choice website, that lists products that have been evaluated by scientists for safer ingredients and more honest labeling.

Obviously, all of us reside in houses where cooking and cleansing occurs daily, so what’s the huge offer? Well, it ends up the chemical substances produced by these activities enter your body from breathing the air, consuming the food you produce, and touching your furnishings.

(************ )The outcomes of the research study are still pending, however permitted the scientists to report that

… regular home activities create considerable levels of unstable and particle chemicals inside the typical house, causing indoor air quality levels on par with a contaminated significant city.

Even jobs as easy as boiling water over a stovetop flame might add to possibly hazardous levels of gaseous air toxins and suspended particles. “Even the easy act of making toast raised particle levels far greater than anticipated,” Vance stated.

Gouw, likewise from UC Stone, mentioned that while we typically think of automobiles as a significant source of air contamination, tidy air supporters have actually guaranteed enhancements because location. In the meantime, we have actually seen chemicals utilized inside your home such as cleaners, glues, coverings, and individual care products end up being a much bigger source of unstable natural substances (or VOCs).

He stated while some toxins (like ozone and great particulates) are kept an eye on by the EPA:


… information for air-borne toxic substances like formaldehyde and benzene and substances like alcohols and ketones that stem from the house are really sporadic.”

However it’s not simply your cleansing items or your cooking options that result in air-borne toxic substances. Heather Stapleton, an ecological chemist at Duke’s Nicholas School of the Environment, likewise informed the audience that her research study revealed that semi-volatile natural substances (SVOCs) were frequently discovered in the bodies of kids residing in houses with vinyl floor covering along with sofas and chairs which contained flame-retardant chemicals.

While the Stone scientists utilized their test home to carry out reseach at will, Stapleton and her group checked kids that were currently residing in houses with these threat aspects.

Regardless of the reality that SVOCs are extensively utilized in whatever from electronic devices to furnishings and “can be discovered in almost all indoor environments,” Stapleton stated “there has actually been little research study on the relative contribution of particular items and products to kids’s general direct exposure to SVOCs.”

In this job, Stapleton and her associates from Duke, the CDC, and Boston University took a look at 203 kids from 190 households in between 2014 and 2016 to determine at home direct exposure to these chemicals by gathering samples of indoor air, indoor dust, and foam from furnishings in each of the kids’s houses. They likewise took a hand clean sample, urine, and blood from each kid.

( Obviously, all U.S. scientist who deal with people, and specifically on kids, are needed to have their research study authorized by a principles board and supply some sort of resources to households who take part.)

When checking the blood and urine, researchers utilized 44 biomarkers to see if the samples suggested direct exposure to toxic substances. In houses where the living-room couch consisted of flame retardant products (particularly flame-retardant polybrominated diphenyl ethers, or PBDEs) kids had a six-fold greater concentration of that chemical in their blood. Kids from houses that had vinyl floor covering in every space (although that was just 9% of houses) were discovered to have concentrations of a substance called benzyl butyl phthalate (BBP) metabolite in their urine that were 15 times greater than those in kids dealing with no vinyl floor covering.

While the majority of the research studies on these chemicals’ function in illness have actually not shown a definitive causal relationship and for that reason need more proof, PBDEs have actually been connected to neurodevelopmental hold-ups, weight problems, endocrine and thyroid interruption, and cancer. BBPs have actually been connected to breathing conditions, skin inflammations, several myeloma, and reproductive conditions.

” There was initially uncertainty about whether these items in fact added to air contamination in a significant method, however no longer,” de Gouw stated He continued:


Progressing, we require to re-focus research study efforts on these sources and provide the exact same attention we have actually provided to nonrenewable fuel sources. The image that we have in our heads about the environment ought to now consist of a home.”

While neither Stapleton nor Vance might be grabbed talk about actions we can require to avoid damage done by bad indoor air quality, the World Health Company has actually long acknowledged the threats of this contamination, specifically on kids, and suggested excellent ventilation while cooking, making use of covers on pots and pans, cleaning up cooking locations, and keeping kids far from smoke to secure them.

However the research study likewise leaves us questioning how to keep our way of lives and keep a tidy house if even cleaning up items can have unhealthy results on health. It’s challenging to break a window in the winter season or in a location where outside contamination is likewise an issue. Kids touch things all the time in shops, schools, and other individuals’s houses that we have no control over. Asking individuals to change their vinyl floor covering or buy a sofa without flame retardant products isn’t constantly financially feasible.

The Asthma and Allergic Reaction Structure of America lists much more sources of home toxins that can impact air quality. While they consist of a long list of things we can do to enhance that quality(however keep in mind that this details is sponsored by Dyson), taking all of the suggested actions might appear frustrating, and the furnishings standards might need big financial investments (for instance, disposing of toss pillows, utilizing just washable drapes, acquiring leather or vinyl couches and chairs, and changing carpets with low-VOC floor covering, and so on).

Nevertheless, a few of the actions suggested by firms throughout the world can supply a helpful start on entering brand-new habits, consisting of taking note of the products any brand-new house products you purchase are made from. Next time you buy cleaning up products, you can get odorless and non-aerosol variations And you can air out your house when the weather condition (and other conditions) allow. Unfortunately, you’ll most likely wish to get rid of candle lights and air fresheners from your house if allergic reactions and asthma are prospective issues. And when you have the cash, you can likewise buy air filters, specifically for locations where animals and kids hang around.

Regrettably, producers are not presently bound by U.S. law to note all components in customer items and labels such as “natural” or ” green” do not always suggest the items are much safer. Much better air quality will need some research study on your part, and it’s finest to discover a trusted source of details( not a producer’s site, which is committed to marketing their items to you). One location to begin is the EPA’s More Secure Option site, that notes items that have actually been assessed by researchers for saf er components and more sincere labeling.
