Scientists agree that studying microplastics in the human body is challenging.
The particles are extremely small, and they are already present in the air, dust, food, and drinking water.
As a result, samples can easily become contaminated during testing, according to National Geographic.
There are several methods for measuring microplastics in human tissue and blood.

However, none of these methods is completely reliable, and many researchers therefore believe that multiple techniques should be used on the same sample.
Research is advancing
New technologies are making it easier to detect microplastics, but there is still disagreement over which methods provide the most accurate results.
According to National Geographic, researchers are therefore working to improve and standardize testing methods.
Some laboratories are also trying to prevent contamination by using steel and glass equipment, as well as air filtration systems.

The big question
Although researchers continue to debate the methods, they agree that the issue is important.
According to National Geographic, more research is needed before scientists can determine exactly how microplastics affect human health.
In recent years, microplastics have been found in the brain, blood, lungs, liver, kidneys, the placenta, and the tonsils, among other parts of the body.
As a result, research is no longer focused on whether plastic particles are present in the human body.

The key question is whether they can harm our health. Scientists do not yet have a clear answer.
