Microplastics found in brain tissue, health risks still unclear

PARIS: Small shards of plastic called microplastics have been discovered in the human brain, but there is no evidence yet whether it is harming us.

These are mostly found everywhere from the top of the mountains to the bottom of the oceans, in which we breathe and the food we eat. They have been discovered in the human bodies, lungs, hearts, drains and even crossing the barrier of blood brain.

The growing supremacy of microplastics has become an important issue in the world’s first plastic pollution agreement, trying to hammer, the latest UN talks in Geneva next week.

The effects of microplastics and even small nanoplastics are not yet fully understood on human health, but researchers are working to find more information in this new field.

The most prominent study of microplastics in the brain was published in the Nature Medicine Journal in February.

Scientists experienced mental tissues from 28 people and 28 people who died in 28 people in 2016, who died in the US state of New Mexico last year, found that the amount of microplastics in the sample increased over time.

This study made headlines around the world when a lead researcher, American poisonous expert Matthew Campaign told the media that he had found a plastic spoonful of microplastics in the brain.

The campaign also told nature that it estimates that researchers can separate 10 grams of plastic from a donated human brain – compare this amount to unused crews.

Speculation ‘far away from the evidence’

But other researchers have since emphasized caution about small studies since then.

“Although this is an interesting search, it should be cautiously pending independent verification,” Theodore Henry, a toxic expert at Herrheat Watt University in Scotland, told AFP.

He added, “Currently, speculation about the potential effects of plastic particles on health is far from evidence.”

“There are not so much data to draw solid results about the presence of microplastics in New Mexico,” Oliver Jones, a professor of chemistry at the Australian RMIT University, told AFP, leaving globally. “

They also found “unlikely” that the brain could add more microplastics than found in raw sewerage – as researchers estimated.

Jones pointed out that the people in the study were healthy before they died, and researchers acknowledged that there were not enough data that microplastics damaged.

Jones added, “If (and this is a big deal if I think) there are microplastics in our brains, there is no evidence of damage yet.”

The study also included images of duplication, the Neuro Science News website Transmitter reported, though experts said it did not affect its significant results.

‘Can’t wait for the full data’

Most research on the effects of microplastics has been observed, which means it cannot establish the cause and effect.

A similar study published in the New England Journal of Medicine last year said that micro -plastex contained in the blood vessels was linked to patients with a heart attack, stroke and death increased risk of death.

There have also been experiments on mice, including a study in Science Advance in January, in which microplastics were detected in their brains.

Chinese researchers said that obstruction of microplastics cells can cause rare blood clots in the brains of mice – while emphasizing that small -fashioned animals are very different from humans.

A World Health Organization survey in 2022 states that “evidence to determine the risks of human health is insufficient” from microplastics.

However, many health experts have cited the precautionary principle, saying that the potential risk of microplastics is needed.

In a report on Microplastics’s health risks by the Barcelona Institute for Global Health, this week’s negotiations published this week, “policy decisions cannot wait for full data”.

“Now, by working now to limit the exposure, improve the risk diagnosis method, and to prioritize weak populations, we can solve this suppressing problem before increasing the wider health crisis,” he added.

Since 2000, the world -born plastics have doubled – and the current rates are expected to increase threefold by 2060.
