The black spatula has recently been identified as an unexpected danger source. Many coverage suggests that the recycled black plastic toxic flame delayed agent may lift into food at a dangerous level. Your cool black kitchen wear may slowly add you to youOne newspaper may be warned and a reasonable reader may share it. Atlantic Conclusion The only safe action policy was to eliminate modest items with this ubiquitous. It turned out that the pier -reviewed dissertation had Calculated the dose 10 timesHowever, this study led the lid to the normal hidden, obviously vague plastic recycling world. So, do we need to re -adjust the black spatula into a cutlery drawer, or is there a true cause of concern?
What is the problem of black plastic?
Recycling plastic, which is fused together from various colors of items, tends to have an attractive sludge color. Therefore, in order to make the product more sophisticated and more uniform, the manufacturer generally added dyes and carbon black to recycled products. When is the problem? these Products will be recycled, so that carbon black pigments will not be effective for optical sensors used to classify different plastic in recycling facilities. The manufacturer is now starting to use alternative black pigments that do not cause this problem, but this problem seems to have created the demand for black plastic made by electronic waste through different recycling streams. Products, such as computers, television, and coffee machines, are usually treated with flame radiators to prevent electrical fire. This indicates that high -level exposure is toxic to humans, which are now prohibited in many countries. However, legacy plastic, including some of these chemicals, seems to be still progressing through recycling chains.
What did the original paper find?
the study, Published in the Journal Chemos Fear, which was viewed in OctoberI am looking at 203 black plastic household goods sold in the United States, such as kitchen equipment, take -out containers, and toys. Researchers evaluate the level of the retardant chemicals of flames called the Decabro Modiphenyl Ether (BDE-209), which cannot be easily disassembled in the environment, and are related to potential human health risks, more than 10 years ago. It was gradually abolished in the United States. However, this study concluded that some kitchen cooking utensils are likely to have 34,700 NG dosage per day of BDE-209.
What was misunderstood?
Embarrassingly, scientists had Calculated the EPA reference amount 10 times。 As a result, the exposure from the estimated BDE-209 black spoon and mistress has decreased to less than one-tenth of the EPA recommended restrictions. The authors do not change the overall conclusion of this error, “there is no transparency and restrictions necessary to ensure safety, so it brings an unexpected exposure to a toxic flame delay agent in household goods.” He said.
Nevertheless, it may change the degree of concerns of the average reader. “When I compare something with reference value, I think that I think it will change the overall flavor a little,” said Joseph, the first scholar who was the director of the Science and Social Bureau of Magil.・ Schwark is an error, Talk to a Canadian post。 “All of this is worthwhile, but you have to do it properly, and you need to make sure your numbers are correct before people scare pants. “
So can I relax?
Although this paper exaggerated, the story emphasized the real trade -off that could be between sustainability and product safety.
“It’s really complicated to start understanding all these materials and where they are going,” said Mark Miodouk, a professor of the London University and a social professor. “Recycled content is good, but if it’s a legacy plastic, they often have these very scary things. Food contact recycling is one of the truly big problems in the packaging world. “
Should I throw away the tool just to make it safe?
There are also environmental drawbacks in disposing of plastic, especially inappropriate environmental disadvantages. “If you decide to remove all the plastic in your home, it may be very important to dispose of what you still use may be very important,” said Adam Heliott, an environmental campaign group. Ta.
There is a way to guarantee the use of plastic more safely. For example, a microwave plastic that is not specially designed to measure a microwave oven may, for example, lewd in chemicals into food. “It’s better to use what you have until it’s no longer used,” said Heliott. “Go out and do not exchange all tapper wear and black Spitsura.”
Is there any other reason to worry about plastic products?
The black spatula appeared on the backdrop of the growing concern about the impact on the health and the environment of the environment, and probably provided a convenient and easy -to -exchange item that people could act based on these concerns. 。 However, experts say that the challenges of managing the risks of plastic use and reuse are much more complicated.
“I didn’t put a black Specra at the top of the concern,” said Miodownik.
He said that it was an additional “eternal chemical substance,” which is increasingly added to plastic food packaging, clothing, and cosmetics and adding PFA, which is on the way to the human body. “The number of products they are involved in is rising and the understanding of human health is limited,” he said. “But they are in our bodies, but more and more, and it doesn’t seem very good to do our body and the environment.”
Similarly, microplastics flow into the water system. Even if the micro plastic itself is inactive in the body, it can function as a vector of other chemical substances with known health effects. Micro plastic means that it is difficult for people to restrict exposure by washing synthetic clothes.
“That’s what we can’t see that we should try to turn on the steering wheel -not vomiting,” Miodownik said. “PFA, microplastic. This technology has reached anywhere, so you need to reduce this technology.”
