Carcinogenic Cribs and Changing Tables?

Thursday, May 08, 2008
Posted by Jennifer Taggart

Environment California has documented high levels of formaldehyde emissions from baby furniture commonly found in the nursery. Environment California’s report shows that cribs and changing tables can emit high levels of formaldehyde. When these sources are added to other sources likely to be found in the home, the levels may exceed those shown to have adverse health effects on children.

Formaldehyde in cribs and changing tables shouldn’t be a surprise. It is common for composite wood products – like particle board and medium density fiberboard (MDF) – are held together with formaldehyde based resins. Unfortunately, the formaldehyde escapes from these products, polluting indoor air. And formaldehyde can be released for many years. But, you might not have thought that a crib or changing table could contribute significantly to formaldehyde emissions in the home. Unfortunately, Environment California’s testing shows that cribs and changing tables can be significant sources. And when you consider that your baby spends a lot of time in that nursery, you might want to look for alternatives. A bit of good news? The California Air Resources Board has enacted a regulation that will start to limit formaldehyde emissions from composite wood products beginning in 2009.

Why is formaldehyde emitted from baby furniture? Wood has naturally occurring formaldehyde. But, more formaldehyde is added to composite wood products to hold together the wood particles. And baby cribs and baby changing tables, along with other similar furniture and cabinets, are typically made of these products. The California Air Resources Board (CARB) reports that formaldehyde off gasses (or escapes) from these products, often for many years. Formaldehyde is released from unreacted formaldehyde present in the resin and as a result of chemical degradation over time. And, unfortunately, porous materials and furnishings, such as upholstered furniture, carpets, walls, and window coverings, can absorb formaldehyde and then re-emit it later. Basically, they act as formaldehyde sinks. So that comfy nursing chair may be absorbing formaldehyde, and the can re-emit it later.

Why do we care about exposure to formaldehyde? Unlike bisphenol A (BPA) in polycarbonate plastic, there isn't much debate about the health effects associated with exposure to formaldehyde. Formaldehyde is a carcinogen. Chronic exposure to formaldehyde is linked to an increased risk for developing allergy sensitization and/or asthma. Several studies have documented that children exposed to elevated levels of formaldehyde are at high risk of developing asthma and other respiratory diseases.

What did Environment California do? It took baby furniture purchased from major retailers such as Target and put the furniture in an enclosed environmental chamber. An independent laboratory measured the formaldehyde emissions from each piece of furniture. Then, the emission rate from the furniture was extrapolated to determine how much the products contributed to the indoor air concentrations of formaldehyde in a typical house.

The results? Of the products tested, the highest emitter, the Child-Craft Oak Crib (purchased at Target), would result in an indoor air concentration of formaldehyde at 20 ppb if it was the only source in the house. Since an elevated risk of asthma has been found in children exposed to indoor air concentrations of formaldehyde at 50 ppb, this is significant. Most homes have many formaldehyde sources, from cabinets to other furniture. Other high formaldehyde emitters were the Bridget 4 in 1 Crib by Delta (Wal Mart), Kayla II Changing Table by Storkcraft (Babies R Us), Berkely Changing Table by Jardine Enterprises (Babies R Us), Country Style Changing Table by South Shore Furniture (Target) and Rochester Cognac Crib by Storkcraft (Target).

So what can you do?

Try these Smart Mama Simple Steps:

• Skip composite wood products.
• Go for non-toxic finishes. If you are buying wood furniture, make sure the coating is non-toxic. Look for natural finishes made with plant oils (although this includes d-limonene), tree resins, minerals and beeswax, or low or no-VOC finishes.
• Just say no to formaldehyde. If you are buying furniture made with manufactured wood products, look for formaldehyde free products. Avoid bare, uncoated urea-formaldehyde pressed wood products that can emit relatively high amounts of formaldehyde.
• Let it off-gas outside. Buying green can be expensive, and sometimes difficult to find. If you can’t find formaldehyde-free particleboard, then let the furniture off gas outside of the nursery, and preferably the home, before bringing the furniture inside. Make sure that the area has fresh air passing by so the formaldehyde will be removed.
• Control climate. The amount of formaldehyde released is increased with increasing temperature and humidity. Keep the humidity and temperature low, and you can reduce the amount of formaldehyde released.
• Seal bare urea-formaldehyde wood products with multiples layers of water resistant sealants. Research indicates that sealing bare urea-formaldehyde wood products can reduce formaldehyde emissions for months to years after application. Seal all unfinished edges of finished furniture. Of course, the sealants themselves may release other VOCs, so check labels carefully. Use a no or low VOC sealant.
• Ventilate. Since babies spend 90% of their time indoors, make sure to keep the home well ventilated. Opening windows and using fans to move and circulate the air will lower formaldehyde levels inside.
• Go green (literally). Some plants have shown an ability to remove pollutants from the air based upon a study by NASA to maintain air quality in confined spaces. Plants shown to remove formaldehyde are those with large leaf surface areas, including Azalea Aloe Vera, Bamboo Palm, Boston ferns, Corn Plant, Chinese evergreen, Chrysanthemum, Date Palm, Dieffenbachia, Golden Pothos, Mini-Schefflera, Peace lily, Peperomia, Mother-in-law's tongue, Philodendron (Heart-leaf, Lacy tree, or Elephant ear), Poinsettia, Snake Plant, and Spider Plant. But, I would consider avoiding those plaints considered poisonous to infants. Also, indoor plants can be problematic. Mold can grow in potted soils and release spores into the air. Houseplants add moisture, thereby fostering the growth of mold and dust mites. No study confirms that houseplants remove significant quantities of pollutants in the home environment, but they may help remove some.

Does ALL particle board/pressed board/manufactured wood contain formaldehyde? My crib and changing table (Jenny Lind from Delta) are made out of some manufactured wood pieces so I called the company a few months ago to ask if there was formaldehyde in these pieces and the VP of Marketing told me no. My daughter’s toy box also has a piece of pressed wood in the bottom and I called that manufacturer and they also told me that it does not contain formaldehyde. Are these people lying? Should I get rid of my crib and changing table before I use them for my second baby? I purchased my particular crib even though I could have afforded a more expensive one because Consumer Reports rated it as very safe.

Lisa - Not all particle board/pressed/manufactured wood contains formaldehyde.  As the blog indicates, formaldehyde based resins are commonly used.  But, as indicated in the simple steps, there are certainly formaldehyde free options available.  The Jenny Lind crib and changing table are both described as solid wood construction, but I have attempted to contact the manufacturer to confirm whether any manufactured wood is used.  As of yet, I haven’t gotten a response.  The Consumer Reports recommendation was based upon safety (hardware failure, etc.) and assembly, not formaldehyde emissions.

Hi Jennifer- Thanks for getting back to me. People at Delta are very hard to get a hold of. I have called 4 times now to find out if the plastic crib rail has BPA in it or not. As far as manufactured wood, the mattress board of the crib and the shelves, sides, back and door of the changing table are all manufactured wood. I spoke to Robin Rozell, VP of Marketing, and she told me that there is no formaldehyde in those pieces. If you speak to someone and find out differently, please let me know as I would like to get a different crib and changing table for my next child. Thank you for your article.

Hi Jennifer,
I recently purchase a bedside table at Target for my daughter’s bedroom.  It has a very strong odor, which seems to be coming from the material the drawers are made from- the odor is not as bad when the drawers are closed.  I am going to move it to the garage, hopefully the smell will go away, but would I just be better off getting rid of it?  I worry about the long term effects it may have on my daughter’s health.
Thanks for your input and your article.

Pam - Without knowing more about the make & model number, I can’t tell you any specifics about the bedside table.  However, many of the “wood” furniture pieces at Target are pressed wood, and a formaldehyde based adhesive is probably used.  Clearly, you have offgassing occuring - hence the noticeable smell.  If you just purchased it, I would take it back to Target for a refund.  Another alternative would be to seal any unfinished edges (usually the drawers) to reduce offgassing - the California Air Resources Board’s research indicates that sealing those exposed, unfinished edges can be effective at reducing emissions.

Hi,

Do you know if the Bassett crib style #5871-0621W from Target has formaldehyde in it?

Also, if we have formaldehyde (pressed wood from Home Depot) on our closet shelves, and keep the closet door closed and the windows open as often as possible, does that solve most of the problem with it?

Thanks,

Pam and all, we have had the same off-gassing problem with our Storkcraft furniture (one of the worst offenders, as it turns out: http://charlottesville.injuryboard.com/defective-and-dangerous-products/new-report-shows-toxic-formaldehyde-in-childrens-furniture.aspx?googleid=240304). We got it last fall and our baby was born in Feb. We thought that was enough time to air out the pieces, but we still smell it when we have had the door closed for a longer period. DS has eczema that is getting worse, and we now suspect it’s because of the formaldehyde because we have no family history of sensitive skin or severe allergies. I’m planning to change his furniture ASAP and hope that helps. Anybody else experience this?

Mar - I couldn’t find that style number on the Target website.  If you have more information, perhaps I can help.

Keeping the doors closed and ventilating your room will help, but it will not eliminate the problem.  You may want to consider also sealing any open edges to reduce emissions.

Heidi - Formaldehyde is not only a sensitiser but also a potent primary irritant.  From a crib or other furniture, your baby is exposed to formaldehyde gas.  Exposure to formaldehyde gas can cause burning sensations in the eye, nose and throat; skin rashes; tightness of the chest and wheezing; fatigue and headaches.  These symptoms may be a result of a primary irritant effect or an allergic sensitization to formaldehyde. 

Formaldehyde is also used to treat fabrics.  Those easy care or wrinkle free sheets are usually treated with formaldehyde.  Frequent or prolonged exposure may cause hypersensitivity, leading to the development of allergic contact dermatitis.  Allergic contact dermatitis can occur through skin contact with formaldehyde containing products or with clothing made from fabrics containing formaldehyde. Dermatitis caused by clothing tends to affect parts of the body where there is greatest friction between the skin and fabric, but this may be hard to tell for sheets where you have full body contact.  Sweating may also play a role - sweating may result in the leaching of free formaldehyde from formaldehyde resins.

Hi Jennifer,
Thanks for your response.  I returned the bedside table to Target.  I checked their website and noted that many of the customer comments on the table also noted the strong odor.  It was the Simply Shabby Chic bedside table. 
Again, thank you for your article.

I have some Capretti furniture purchased from USA Baby.  It has smelled really really strong ever since it was delivered before our baby was born, and it still smells.  The smell comes from inside the drawers.  Everything that’s in there stinks like chemicals.  I’ve been hoping it would go away, but it hasn’t.  I can’t find any information on this brand and the formaldehyde.  Do any of you know anything?
