Baby Poop Loaded With Microplastics


All told, PET concentrations were 10 times higher in infants than in adults, while polycarbonate levels were higher between the two groups. The researchers found a much smaller amount of meconium polymers, suggesting that babies are born with plastics already in their systems. This echoes previous studies found microplastics in the human area and meconium.

What all this means for human health – and, more urgently, for the health of the child – scientists are now seeking to find out. Different types of plastic can contain at least 10,000 different chemicals, a quarter of which people are concerned, according to a recent study from researchers at ETH Zürich in Switzerland. These additives serve all different purposes in making plastic, such as providing speed, extra strength, or protection from UV spraying, which degrades the material. Microplastics can contain heavy metals such as lead, but they also have a tendency to and heavy metals and other impurities as it collapses around. They also quickly grow a microbial community of viruses, bacteria, and fungi, most of which human pathogens.

Of particular concern is a class of chemicals called endocrine-disrupting chemicals, or EDCs, that break down hormones and are linked to reproductive, neurological, and metabolic problems, for example increased obesity. The bad plastic component bisphenol A, or BPA, is such an EDC -linked various cancers.

“We should be concerned because EDCs in microplastics have been shown to be associated with many adverse outcomes in human and animal studies,” said Jodi Flaws, a reproductive toxicologist at the University of Illinois at Urbana-Champaign, who led a 2020. study from the Endocrine Society on plastics. (He was not involved in the new research.)

Infants are especially vulnerable to EDCs, because the development of their bodies depends on a healthy endocrine system. “I strongly believe that these chemicals can affect early life stages,” Kannan said. “That was a weak time.”

This new research adds to a growing body of evidence that infants are especially exposed to microplastic. “This is an interesting paper with some worrying numbers,” said University of Strathclyde microplastic researcher Deonie Allen, who was not involved in the study. “We have to look at everything a child is exposed to, not just their bottles and toys.”

Because babies pass microplastics in their feces, that means the gut can absorb certain particles, just as it absorbs nutrients from food. This translocation is known: Especially small particles can pass through the lung wall and end up in other organs, including the brain. The researchers actually it is shown of carp by feeding them plastic particles, which pass through the intestine and go to the head, where it causes brain damage shown as behavioral problems: Compared to prevent fish, the individuals with plastic particles in their brain are less active and eat more slowly.

But that is done in a much higher concentration of particles, and in a very different way. While scientists know that EDCs are bad news, they do not yet know what level of microplastic exposure will cause problems in the human body. “We need more studies to confirm the doses and differences in microplastics chemicals that lead to adverse outcomes,” Flaws said.

Meanwhile, microplastics researchers say you can limit children’s contact with particles. Do not prepare baby formula with hot water in a plastic bottle-use a glass bottle and transfer to plastic once the liquid reaches room temperature. Vacuum and sweep to prevent microfibers from staining floors. Avoid plastic wrappers and containers if possible. Microplastics contaminate every aspect of our lives, so while you can’t get rid of them, you can at least minimize your family’s exposure.
