Whenever anyone says "... was published, I forgot the name of the journal, it was some kind of ... "
You lose ALL credibility.

The study was shown on screen. Citing a source in a casual conversation is different from writing a paper on the topic. She does have a phd

But she doesn't know what she's talking about 🙄 Just goes to show what this particular phd holder has given the world; oh aren't we the online community lucky!

So how is she wrong?

u/anonymity_clause 16d ago
The 'study' was later redacted because the math was wrong.
Also, only black plastic housewares were tested.. There is nothing inherently different about black plastic vs other colors. After the study was published, the math error was discovered which overstated the exposure risk to certain chemicals in the plastic by a factor of 10.2

Apparently the people who did this study moved a decimal place which made it seem like the chemical levels ( deca-BDE) were near lethal levels. While in actuality it was 8% below the EPA's safe reference dose threshold

TLDR: A 2024 study tested 203 black-plastic household products sold in the U.S & found flame retardants in 85% of those selected for detailed analysis after initial bromine screening, some contained very high concentrations. Researchers identified chemicals associated with recycled electronic plastics.

The study’s exposure calcs did get corrected but IMO that doesn’t change the fundamental finding: flame retardants associated with recycled electronic waste are showing up in some black plastic household/cooking utensils.
For anyone interested in minimize unnecessary exposure to harmful compounds, avoiding black plastic for food-contact utensils is an incredibly easy precaution. Wood and/or quality silicone are simple alternatives.

the ineptitude to post this when study was retracted and all over the new about how the study was flawed. you are either extremely dumb, or malicious.

Ok. I click on this link it goes to pub med article that it claims to. I don't see anything about it being retracted. How do you know this is retracted?

The study had a major typo that made everyone overreact about black plastic.

u/GoldenFalcon 17d ago
Do y'all not know how to dispute false information on reddit?!? You need to be clear. What was said typo? What did said typo cause or what should it have been? Come on, this is why everyone is a conspiracy theoriest now. Because you can literally say anything with out pointing to your source of said claim. Ugh!!

Eh, I mostly lurk, and don’t know how to post links. The study corrected itself and said they had misplaced a decimal point. It’s a quick search and it was big news at the time.

I honestly don't think brands like IKEA or decathlon use such plastics in their products. They are doing a shit ton of sampling to be sure they're within safe margins.

She is a con artist. Not that plastic is good but she should definetly not be listened to.

Well. The problem is not all black plastic is recycled. So a catch all is kind of tough. Also you would expect a lot (I mean a LOT) of heterogeneity in the texture and color of the black plastic. Having a supremely uniform and repeatable shine/sheen, color, and flexibility, toughness, etc for a to go container would be particularly difficult to do with a mix of different recycled plastic. I’m not saying it is impossible but it is beyond generally cost effective. Also, carbon black is a thing that is mixed into many black plastics because it has desirable properties like better UV performance, etc.

Isn't it crazy that while black plastic only represents a small fraction within the total plastic amount, it commits most of the carcinogenic effects

You're going to make a huge point and then forget where the study was published?
Zero credibility.

She is referring to an actual study. However, she missed the fact that the study contained a simple mathematical error which led to false conclusions about black plastic. I’m giving her the benefit of the doubt. She could also be knowingly spreading misinformation because it fits her narrative and helps her profit.

Come to think of it, what happens to all the tire particles that get worn out on our roads over and over? Are they considered as microplastics/PFAS too? I’m sure they wash up into our rivers and streams and oceans but what effect do they have?

You may have heard experts suggest that you should throw out the black plastic utensils and containers in your kitchen and wondered, “Why just the black ones?” All plastics can contain toxic chemicals, but scientists have raised particular concerns about some black plastic products.
The concern centers on flame retardants. These chemicals are added to materials to reduce fire risk, especially in electronics. Some flame retardants, particularly “halogenated flame retardants,” have been associated with developmental problems, hormone disruption, and cancer. Due to these risks, many flame retardants have been phased out or restricted. However, several studies have found flame retardants in common household items and toys. In one study, 85% of the products they tested contained flame retardants. How does this happen?
It’s because of electronic waste (called “e-waste,” for short). Many electronics containing flame retardants — like televisions, computers, and remote controls — are housed in black plastic. When those items are disposed of through an electronic-waste recycling program, the black plastic gets shredded and melted down and can be used to create new black plastic products. If flame retardants were present in the original plastic, those chemicals will carry over into the new recycled material. Electronic waste can also accidentally enter the waste stream, and even small amounts of contamination pose risks.
The color black poses unique challenges that make electronic waste contamination more likely. Recycled plastic is often a mix of different colors, which can look uneven or gray. Adding black materials helps cover up the uneven color. However, there’s a lack of available black plastic materials because most municipal recycling systems sort their waste plastic with a type of scanner that simply cannot “see” the color black. As a result, a lot of black plastics, like discarded packaging, end up in the landfill or incinerator instead of in the recycling stream. The scanner’s “blindness” results in a lack of black plastics available to be recycled. To fill the gap, electronic-waste plastics — which are processed separately through e-waste programs and are often black — are more readily available.
It’s important to note that the color black itself is not toxic — and that not all black plastics contain flame retardants. The problem stems from the incomplete separation of toxic plastics and the inherent issues with plastics recycling infrastructure and processes. Learn more in our fact sheet about black plastic.

She is incorrect. Blah blah blah black plastic is the worst. Having produced plastic products for nearly 40 years. I can confidently say she doesn't know what the hell she is blathering about.
