1) It's important to note that the article title is actually: Flame retardant may cause hyperthyroidism in cats
2) Of note, they determined that a p-value of <0.10 was considered statistically significant, and of the studied compounds TDCIPP was the only one with significant odds ratio of exposure being associated with hyperthyroidism in cats (1.36, p value = 0.059).
3) Look. Organophosphates are probably one of those things that we should continue studying in detail. They seem more trouble than they're worth. But I don't think I'd hang my hat on this study alone.
The article shows that a flame-retardent increases risk of autoimmune condition with 94% confidence.
And you downplay it because... it's less than 95% confident? (by the way, the paper finds its main finding at p < .02)
To my mind, a major post-mortem is necessary, government funded. How many other flame-retardents cause health issues? How did they get past approval?
In the meantime, an immediate injunction against flame-retardent laws should be passed (numerous tobacco-lobbied laws REQUIRE retardents), and all used retardents should be listed on the labels of all products.
I expect the people in charge of public health to be as anal about their job as I am about mine.
Ah, I see what you're saying on the survival curve, thanks for the point out! I agree that's an interesting statistic, and it'll be interesting to see further studies investigating flame retardants. I'd be very interested in human studies, as I myself have thyroid issues (albeit more familial than anything).
That being said, I'm not sure that you can claim that hyperthyroidism in cats is an autoimmune condition. I also am interested in what the effect size of this correlation actually is. We see the data that says that cats in 1995 had 20x lower rates of hyperthyroidism, but we don't have any additional information on how many cats were actually being screened for that. It's like saying (hopefully this isn't too controversial) the prevalence of autism is higher today than it was 20 years ago.
That's an interesting question you bring up though, whether or not we should immediately intervene based on animal studies. And this is something we should probably extend to human studies, and as far low level as basic science studies. Where do you draw the line? Do you ban cell phones? Wifi? Milk? Meat? Coffee? Aspartame?
And finally - Do you require all compounds to be listed on labels of all products? Or just some? How many compounds? Only when we find correlations? Or prior to that based on empirical evidence?
So the statistical term for what you're saying is that the paper didn't use bonferroni correction. Which is relevant (but unrelated to the p < .05 arbitrary boundary).
> That's why investigation is done until there are many more 9's
Nobody said the investigation is done. What is being said is that this alone is a red flag that warrants a lot of investigation (and the investigation shouldn't have to be research by colleges whenever a graduate student gets around to it). This is something the EPA should fund an attempt to reproduce.
It's the EPA's job to prevent dangerous chemicals from being sold in public goods. It's not college's job to need to conduct exhausting studies with absolute proof with many 9s that something is unsafe and then hand it off to the EPA to act. Once any reasonable doubt is raised the EPA needs to take ownership.
This investigation is the bare beginning. It may turn out to be completely wrong. It does not warrant 'a lot of investigation'. There are so many spurious results out there, it would be a fools errand to dig into every curious result.
And no I did not mean some correction. I meant, that publishing is a filter for any seemingly correlated result. It will inevitably include simple coincidences, because of the sample sizes involved.
To put it simply, all coincidental results end up being published, because they look so remarkable. It's a reason to be very skeptical of small samples.
>>> I meant, that publishing is a filter for any seemingly correlated result.
Great, we all know what publication bias is. Sure there's a non-zero chance that this is a statistical anomaly.
But my dude, what exactly is going on in your head? Numerous flame retardants have already been found dangerous and toxic [1]. Are you seriously concerned people are going to take their health too seriously and throw away their couches because of this study?
I think the exponentially more likely, and exponentially more dangerous concern is these flame-retardant chemicals aren't taken seriously enough... particularly since it's debatable whether they were ever necessary in the first place.
What's going on is, the 'emotional outrage of the minute' eco-topics that keep coming up. I have limited investment to spend in outrage. I'm not spending it on every preliminary report that might show some correlation.
For instance, tiny cats (6lbs? 10?) that sleep on furniture for 8-10 hours a day show elevated flame retardant in an absorbent tag.
Do the cats respond in the same way as humans to these chemicals? (No)
Is the acceptable dose for a 10lb cat different from a 100lb person? (Yes)
Was anything else measured in the experiment (No?)
Did the experiment seek out any other explanations? (No)
This reeks of a cherry-picked goal-directed experiment to create outrage. It seems the opposite of science.
> and of the studied compounds TDCIPP was the only one with significant odds ratio of exposure being associated with hyperthyroidism in cats (1.36, p value = 0.059).
Am I correct in reading that they tested 24 different compounds (or compound groups)?
Its insane. I always hear that level of chemical is so low it has no negative effect on a person. But you add up all the low levels of toxic chemicals and they add up to something significant! Pesticides, detergents, personal products such as perfumes, hair dye, make-up.. oh gosh. The list goes on. People are drenching themselves in chemicals then take pills to mask the effects.
And its expensive to avoid these things, my family of three spend about 2K per month on food alone trying to eat healthy. Nothing extravagant, fruits, vegetables, and organic when it matters. Sure we could live on $400 with highly processed or fast food... but you feel terrible afterword. The longer you stay away from them the more sensitive you are to toxic food.
I always see Americans with these crazy quotes for healthy food. I'm very curious what you spend the 2k on.
Here are some prices for central Europe. Kg of rice is 1 euro. Kg of oats is 1 euro. Potatoes and other tubers and root vegetables, even less. Cherry tomatoes, maybe 4 euros per kg. Lentils, peas, chickpeas less than 2 euros per kg. Whole chicken maybe 4 euros per kg. Chicken breasts are like 7 euros per kg if you don't want to bother with cutting it up. I think meat in general is cheaper in the USA (but quality may differ).
Do you guys eat a literal ton of vegetables a month, or do we have different ideas of what healthy food refers to?
Food in other countries is so much better and cheaper. We stayed in Mexico for a few months (not saying I want to live there) and food was all organic and dollars. A bag of about 15 avocados cost $1-$2 dollars. In the US that will buy you maybe one avocado.
Dozen eggs = $5-$8
Bag of apples = $5
We have some food allergies such as sensitive to gluten (wife is celiac).
Two things broken in US (that are pain points for us now) - food cost and healthcare. I pay about $800 month for healthcare that is essentially a safety net for an accident ($5K deductible). I am not sure why universal healthcare is not viewed the same as public schools. Many people dont have children but still pay taxes for schools and education. I would probably pay less than $800/month in extra taxes for healthcare.
american here, $2K per month sounds like a pretty wild food budget for a family of three (one of whom is presumably a child). I spend $300-400 a month to feed myself, and I could cut that down a lot if I didn't primarily shop at whole foods. if you aren't focused on saving money, there are a lot of opportunities to spend extra money on stuff that isn't healthier (eg, prime NY strip vs flank steak, fancy aged cheese, high end butter/oils). the nicest version of something in a grocery store can be 2-3x as expensive and nutritionally equivalent.
> Its insane. I always hear that level of chemical is so low it has no negative effect on a person.
At some point lead in gas was "safe", lead in paint was "safe", asbestos was "safe". Safety is an afterthought, and in some cases I'd bet my left nut that the long term negative effects are even desirable : cause a disease, sell the cure, profit
Longer yes, healthier... Hard to judge. We weeded out a dozen nasty things, but got others in return, for which "chemicals" might be an explanation. Parkinson's and Alzheimer's come to mind here.
We were smart enough to add lead to fuel, so I absolutely wouldn't be surprised if something we mindlessly use today is actually super unhealthy too. People often seem to suffer "End of History" syndrome when judging these things. "Yeah we were stupid back then but today's scientists are smart."
If people try to avoid processed food, products containing a lot of suspicious "chemicals", use the washer's program that does an extra rinse-run and whatnot I don't think that's entirely unjustified.
Life expectancy is going down in the US, obesity is skyrocketing, &c. The foundations are collapsing while we're maintained alive by machines and pills. You can live healthier than ever if you consciously chose to, most people don't make that choice.
> And yet we live longer, healthier lives than humans ever have.
Do we?
> Analysis of the mid-Victorian period in the U.K. reveals that life expectancy at age 5 was as good or better than exists today, and the incidence of degenerative disease was 10% of ours.
The major medical advances have been sanitation, antibiotics, and vaccination, which have saved the lives of millions of children. We are otherwise much unhealthier than most people in the past, unless they were unlucky enough to grow up in times of famine, which was not common - though, in all fairness to the modern world, famine has been essentially eradicated altogether in advanced countries.
I should also mention, we dont eat out / order in food. our budget is probably not much higher than most once you factor in the restaurant/takeout/food delivery budget.
The lobbying efforts of the manufacturers of the chemicals are a major contributor:
The legislators wrote that the “worst tactics outlined in the Chicago Tribune series — which we each saw some of firsthand in our states — included: deliberately misrepresenting the science around flame retardant chemicals relating to both their effectiveness and their health risks; employing an expert witness who repeatedly invoked a phony story of a child dying in a fire in order to justify flame retardant mandates; creating a front group called ‘Citizens for Fire Safety’ to counter the opposition to flame retardants among firefighters and health organizations; and using racial profiling to mislead community leaders about the impacts of toxic flame retardant chemicals.”
...
These powerful industries distorted science in ways that overstated the benefits of the chemicals, created a phony consumer watchdog group that stoked the public's fear of fire and helped organize and steer an association of top fire officials that spent more than a decade campaigning for their cause.
Its fine to act with limited information but not acceptable to stop paying attention until a problem becomes orders of magnitude worse than if you'd closely monitored the intended and unintended effects from your actions.
> The cats wore the tags for a week and owners filled out a questionnaire. Once collected, the tags went through a process to extract the chemicals by soaking them in a solvent.
Do we use these tags for humans? Would be cool to see what sort of chemical exposure we get.
The next paragraph mentions human equivalent items:
> The feline passive samplers—similar to a rabies tag—are produced out of the same material used in the silicone wrist bands invented in Anderson's lab for measuring exposure to environmental chemicals in humans, including after Hurricane Harvey in Houston in 2017.
You can use something such as awair (https://www.getawair.com/) to track your indoor air quality (voc's, etc.).
In the first few weeks of owning one we realized if we leave our bedroom door open the CO2 is much lower while we sleep. Our quality of sleep has improved.
Your last point is particularly nice. If you happen to be blessed with good genes you’ll get cheaper insurance. But what about the people who will be rejected because of their genes?
Can you be rejected instead of higher premium? IMO that's the case where gov should pick up the tab.
Also not having insurance doesn't mean instant death sentence. You can still pay yourself, however crazy amounts they are.
Disclaimer: I think whole US healthcare system is insane, especially the part where employers negotiate better rates. It's like socialised healthcare where higher earner pay more, but without any benefit to private companies...
>GINA prohibits health insurers from discrimination based on the genetic information of enrollees. Specifically, health insurers may not use genetic information to determine if someone is eligible for insurance or to make coverage, underwriting or premium-setting decisions. Furthermore, health insurers may not request or require individuals or their family members to undergo genetic testing or to provide genetic information.
It’s a public health menace that has also been implicated with childhood maladies. There’s some weak links to autism and allergies. Of course most people will dismiss this as conspiracy theory, but eventually the science will catch up.
Seem alike rooting out actually toxic substances, like leaded gasoline, is so important. Kudos to the experimenter here for the clever experimental design (cat collars that absorb chemicals for later study).
The title of the article doesn’t says that hyperthyroidism is 20x times higher because of flame retardants. I’m not sure if the article’s title was changed, or edited by the OP.
The odds ratios for the levels of thyroid hormone in cats exposed to the compounds detected are no higher than 1.61x times higher.
The 20x increase is an increase over time, and isn’t explained by the paper or the article.
I wonder what fraction of modern disease, and what conditions, are due to prolonged low-level exposure to random slightly toxic chemicals. I wouldn’t be surprised if we found out that relatively recently diagnosed conditions like autism are the result of some random seemingly innocuous product like shampoo detergent or sunscreen or something.
Bruce Ames, at the University of California, devised a method of screening for mutagens, using bacteria. One of his graduate students using the technique found that the flame retardants in children's pajamas and bedding were powerful mutagens, and were probably causing cancer. That event made Ames a celebrity, and in the 1980s he went on a lecture tour supported by the American Cancer Society. His lectures reflected the doctrine of the A.C.S., that industrial chemicals aren't responsible for cancer, but that individual actions, such as smoking or dietary choices, are the main causes of cancer. He used a fraudulently "age adjusted" graph of cancer mortality, that falsely showed that mortality from all types of cancer except lung cancer had leveled off after the A.C.S. came into existence. He described tests in which he had compared DDT to extracts of food herbs, and found DDT to be less mutagenic than several of the most commonly used flavoring herbs. His message, which was eagerly received by his audience of chemistry and biology professors, was that we should not worry about environmental pollution, because it's not as harmful as the things that we do to ourselves.
I mean --- if you thought it was safe, wouldn't you prefer children's clothing to be less flamible?
Children can be very heavy sleepers and not hear smoke alarms, and even if they do wake up, they might have a harder time getting out of a burning building than adults, so having a bit extra time because their clothes didn't catch fire would be helpful.
Seems like a good idea, until you consider the negatives of the fire retardants, and then you have a complex decision to make.
The problem is that companies introducing chemicals into a clothing product aren't required to show that they're safe, at least in the US. So considering the negatives only happens much later, if at all.
Can fire retardants be filtered by commercial off-the-shelf Air Filters?
If yes what type of tech or air filter type would filter these? For the sake of 'neutrality' would prefer a discussion focused on the working principle of the filter tech instead of just casual 'product naming'.
I think you have to have one that can capture VCOs, which puts you into expensive, but still considered normal consumer (as opposed to professional/enterprise/commercial/etc), products.
So, I'd suggest offhand to look at IQAir and Austin Air products to see if any of them state they can grab OPFRs. Their bottom level products probably won't.
If you own your residence, and live somewhere with good air quality most of the year, forget about air filtering and go for air changeovers. Read about ERV/HRV.
Activated carbon filters are inexpensive and remove VOCs but in my experience not terribly quickly.
> Many furniture manufacturers are no longer using flame retardants, thanks to an update to California's furniture flammability standard, TB117-2013. Most furniture that meets this standard will also include a label stating whether the product contains flame retardants.
Basically look at the tag if it was manufactured recently.
I'm not surprised, there does seem to be a pretty big overlap between people using healing crystals if you know what I mean, and people avoiding actually harmful chemicals.
Same principle as "why vegans live healthier". It's not because their diet is actually healthier per-se, same as healing crystals do not work. But a vegan person, same as a person using healing crystals is likely to be a strongly biased sample of the population. They tend to be more aware of their lives, their bodies and the consequences of what they do to their bodies. And that, as a net effect, yields a healthier lifestyle on average.
But an unhealthy person will never get healthy by eating vegan, same as they won't get healthy by using healing crystals. It only works if you embrace the lifestyle and accept it mentally and become a "biased sample" yourself.
> Basically look at the tag if it was manufactured recently.
Unfortunately, it's not that simple. The update to the CA law is that manufacturers are no longer required to include flame retardants. They are still allowed to. I was surprised that even at a high-end furniture chain (Restoration Hardware), they were unable to tell me whether their furniture contained flame retardants or not.
In general: be prepared to pay significantly more for natural fibres and fillings.
If you're in the UK, it's harder than that. You either find one of a handful of small companies that are prepared to interpret the law more leniently, or you import from somewhere else in the EU.
These chemicals are also in carpets, and here you're in a worse bind, because the natural fibre alternatives are generally treated against insects and/or impossible to properly clean.
This website (which I'm not sure strikes the most helpful tone) has more on the UK situation: http://www.toxicsofa.com/
From research I did, the flame retardant in carpet is actually mainly in the padding. So I compromised on a wool underlayment and regular nylon carpet. The underlayment was not cheap but on the whole the cost was not that much higher.
In the SF Bay Area, we found a company selling natural latex mattresses, no flame retardants added. The showroom was on University Avenue in Palo Alto, so the price was high (at least $3K for a queen). But the factory was in Marin, so they could do custom sizes, and then we asked about replacing all our couch cushions, and we could special order those too. So we replaced all our mattresses and couch and chair cushions with natural latex. For covering and waterproofing, we also bought a natural wool mattress cover.
Sorry, I don’t remember the names of the businesses, but this was 10 years ago when the flame retardants were mandatory for synthetic materials. I don’t even know if they are still in business.
For chairs that had built in padding, we bought 1960s and 70s furniture from thrift stores with the hope this was before flame retardants were in use. We did all this after my partner and our female cat developed Hashimito’s, had years of low energy, and needed daily thyroid medication.
Furniture already comes with a covering, but the chemical manages to seep through (I'm assuming it's been applied to the foam itself). For a volatile chemical, adding yet another fabric covering may not help. Maybe a super thick quilt or a fabric that isn't porous would work?
Any furniture we buy we always leave it out in the sun as long as possible to off-gas (release toxins) then leave it in the garage for a few weeks to further loose that new 'furniture' smell of chemical.
We've been introducing new flame retardants, discovering they are toxic, rinse, repeat on a 10-year cadence since something like the 70's. We're just about coming due for the next wave of discovery.
It's more about what happens when you toss your phone into the landfill after two years, and the mountain of dead electronics starts leeching toxins into the groundwater.
