‘We did not expect to find [this]’

As seen in the images, the accumulation of plastic in landfills and in nature is a known problem. shocking amounts Waste has created a mess over the years.

But a surprising discovery deep inside the lungs of living humans has further revealed how important the problem is and that it could have significant implications for public health.

What happened?

Guardian in April 2022 reported Of the patients who underwent surgery, 85% (11 of 13 sampled) had microplastics “settled” in their lungs. Small particles from materials frequently used in SiEnglishE-use bottles and plastic packaging were the most common.

“We did not expect to find the greatest number of particles, or particles of the sizes we found, in the lower regions of the lungs.” in question Laura Sadofsky, senior author of the study published by the journal Science HEf Total Environment.

“This is surprising as the airways are smaller in the lower parts of the lungs, and we would expect particles of these sizes to be filtered or trapped before traveling this deep,” he added.

The research was based on work from two previous studies that also found microplastics in lung tissue. In these cases, samples were taken at autopsy.

Why is this worrying?

Scientists are still investigating the impact of microplastics on our health, as well as the negative effects of much smaller particles called nanoplastics.

But their discovery caused alarm.

A study available in 2022 Spring Connection described both microplastics and nanoplastics as “emerging contaminants” and called for “further investigation” into their cancer-causing properties.

What is being done against microplastics?

research process an important step towards a deeper understanding of the issue to eventually raise awareness and create new policies that will benefit human health.

“These data provide significant progress in the field of air pollution, microplastics and human health,” Sadofsky said. said Guard.
