Toxic School Construction
Question from jo
Hi, Hoping that you and your readers can offer me some insight. My daughter is scheduled to start 1st grade next fall. The school she is supposed to go to has had some serious construction/renovation/additions. The odor was so overpowering this year that I pulled her out and had her go to an overflow school that she previously went to and that has had no construction. In the fall she will have no choice but to move to the school with all the outgassing. They are scheduled to do huge amounts of additional construction starting in jan 2013 and to continue through the summer, so no doubt the outgassing will be even worse when she is to start in the fall. My other option is to try and “choice” her into a school nearby. Unfortunately that school is a little less than 1/2 mile from a major highway. It is not inner city but more treed suburbia. But still that is a lot closer to highway pollution than I would prefer my 5 year old to spend 7 hours of each day. So how do I know which is worse? help!
Debra’s Answer
Well first of all, you do have a right to have your daughter have a safe environment at school, and you are right that new construction will be outgassing toxic chemicals, particularly since they probably are taking no precautions otherwise.
I would consider her regular school to be more toxic with the new construction, than a school without construction 1/2 mile from a freeway.
But could we think outside the box here? New construction is likely to make all the children sick to one degree or another. Could they do less toxic construction? Move classes to a different building? Could some parents get together and homeschool children until the new construction is done outgassing?
Go to the school board now and voice your concerns.
Minwax Oil-Based Wood Stain Marker
Question from Rachel Jones
I am looking for mcs safe housing. I found a really good place except that the landlord recently used a minwax oil based wood stain marker on a few areas that had been knicked (the wood on the walls). Three areas in all. It was done over a week ago. they don’t open the windows because corn is nearby and they are concerned about particulate debris. Do you know how long it might be til it is safe? They were small areas apparently but I smell it as I walk in the house. Is there a safe way to remediate it so I can live there? I have had bad experience with minwax floor finish in the past.
Debra’s Answer
It will eventually outgas. Heat will make it outgas faster. Since they are small areas, I would think you could take a hair dryer to those areas to speed drying time, but make sure you have ventilation and wear a mask or have someone else do it.
Oil Paint Still Toxic?
Question from Irene
I purchased a furniture set made mostly of birch wood (manufactured by College Woodworks), however, it was painted with oil paint. Two years passed since the purchase, and I can still recognize some smell coming from the paint. Is it toxic? Thank you for your answer in advance.
Debra’s Answer
It can take oil paint a long time to cure completely. If you are still smelling it, it’s still emitting chemicals that are no less toxic than they were two years ago.
Heat can make it outgas faster.
How do I know if Naturepedic mattresses REALLY are organic?
Question from amy
Debra so naturepedic claims to have organic mattresses……how do i know that these mattresses are truly organic? What questions should I ask the representative that I talk to, what should I look for. I made the mistake, not knowing about offgassing and last year purchased my son a typicaI mattress which i am sure is flame retardant. I feel terrible….I feel like I need to have him sleep in something else until I replace it, but I want to get it right this time. Please help!!!
Debra’s Answer
You know that Naturepedic mattresses are organic because they have certifications by independent third parties and display their certification certificates on their website (see www.naturepedic.com/certifications/).
They are a GOTS Certified Organic Mattress Manufacturer, which means that GOTS has examined the entire manufacture of their mattress and found it to meet their stringent standards from start to finish.
Note that Naturepedic displays ALL their certification certifications to substantiate their claims.
By contrast I just want to tell you a story. Recently I called a major mattress manufacturer who is making environmental and health claims about some of their mattresses. Their website does not substantiate the claim. I called them for more information about a claim they had made that part of the mattress material was certified to be free from hazardous chemical emissions. They had no certificate. It wasn’t just that it wasn’t on their website, they didn’t have the certificate at all. I was told that the certificate was issued to the manufacturer of the fabric. They didn’t even get it from the manufacturer. They wouldn’t give me the name of the manufacturer that held the certificate. Needless to say, I am not recommending this mattress to you.
This is how you tell if something really is what it claims to be. You ask for substantiation of claims. You look at the integrity of the company, their reputation, who’s recommending them.
Are There Any Safe Silicone Bakeware Products?
Question from Sarah
Are there any silicone bakewear products that are safe? What to watch out for? I saw a popsicle mold today advertising “made with ” polypropylene” Is this really safe? Presidents Choice brand. thank you!
Debra’s Answer
Silicone bakeware products have been discussed elsewhere on this site…but I wanted to answer this question because of the way it was asked.
“Silicone” is NOT “polypropylene.” They are two completely different substances.
Polypropylene is one of the safer plastics, if you are going to use plastic. It’s the plastic used to make plastic sandwich bags and food storage tubs. So if you are comfortable using those, feel comfortable using this popsicle mold.
Should you not use polypropylene? It’s not high on my list of the most important things to avoid, but if I have a choice to use some other material, I do.
Dichlorobenzene in Mothballs Affects Endocrine System
According to a new study by the Centers for Disease Control, girls exposed to high levels of dichlorobenzene had their first period seven months earlier than girls with lower exposure.
The age when a girl has her first period has fallen over the past century from an average of 16-17 years to 12-13 years.
This study is the first to link dichlorobenzene with the age of girls’ first period. In addition to mothballs, dichlorobenzene is found in solid blocks of toilet bowl deodorizers and air fresheners.

One BPA Exposure May Vanish as Paper Register Receipts Become Obsolete
Paper register receipts are on their way out, but not because they are toxic or waste natural resources.
Merchants want to move to a digital payment system so they can get more information about what we buy.
At least we won’t get BPA all over our fingers when we buy something.

Fire Retardant in Polyurethane Foam Cushion?
Question from Ali
I have custom window seat cushion, which I had made in 2008. The insert is polyurethane foam, and I am concerned that it may be coated in chemical fire retardants. The fabric cover zips off, so theoretically I could replace the insert with an all natural latex one, but I’m wondering about chemical residues on the fabric. Do you know if washing will remove them? Is there any special soap or rinse that would work? I have heard vinegar can be effective but I’m not sure if that’s true. Or is the fabric permanently unsafe (it was very expensive handmade fabric, which is one of the main reasons I’m trying to salvage it)? Thank you for any advice you can offer!
Debra’s Answer
This is an interesting question.
I’m not sure that polyurethane foam purchased separately from a piece of furniture necessarily has fire retardants on it, as the fire retardant laws refer to the item not the materials it is made from. I can’t guarantee one way or the other.
As for removing fire retardants, I think it would be very difficult. Fire retardants, like water repellants, or wrinkle preventors, are designed to be present for the life of the fabric. If it could be washed out, then the fabric would no longer be fire retardant, or water repellant or wrinkle free.
Wish I could give you a better answer.
Roof Mold
Question from TerryAnn
Living here in the Northwest, we all get roof mold. I am very concerned about using any toxic products that would wash down into the yard and be around where my dog could walk through it. Even using a pressure washer to wash it off will result in all the gravel-y pieces from the roof being washed down into the yard, and I am certain that my roof shingles are made of toxic products. How can I get rid of mold on my roof without turning my backyard into a toxin zone?
Debra’s Answer
Good question!
I have no experience with this. Readers, any suggestions?
Toxic Materials in Baby Mattress?
Question from Hannah
So, I know you have addressed polyurethane quite a bit. But my question is regarding a mattress made by a company called Cotton Cloud, here in Portland, Oregon. They claim to use no flame retardants besides boric acid in some models. The particular model I purchased is wool, without Boric acid. However, it does have polyurethane foam core. The salesman told us that the poly foam is “untreated” and the entire mattress contains no carcinogens, chemicals or fire retardant treatments. It is wool, cotton and the foam. They do make a model with springs instead of foam. I don’t want anything toxic like polyurethane foam since this mattress if for my infant, and I have a 14 day return option to exchange for the (less firm) spring version. So, is it possible for the poly foam to be untreated? If so, is it still toxic? Also, the wool & cotton are not organic- so I am curious as to what they may be treated with.
Debra’s Answer
I can’t speak to those specific materials without more information, but I will tell you in general
Especially for an infant, I would get the purest materials you can afford.
