A pair of environmental scientists are warning that populations worldwide may face another health crisis – disease that affects people due to the ingestion of microbes. In his perspective published in the journal Science, A. Decreth, along with Vrij Universite Amsterdam and Juliet Legler, University of Utrecht, note that the effects of ingesting microplastics on the human body are unknown.
As the authors state, prior studies have shown that microplastics have made their way to almost every part of the planet. As an example, a team of researchers recently found that more than 1,000 tonnes of microplastics fall on national parks in the US each year. As a result, organisms continue to affect them either by inhalation or by swallowing foods or water. The list of creatures that affect plastic includes human beings, but certainly no one knows what the effects are.
In particular, research to date has not been done correctly — a group of researchers recently found that environmental microplasty is more intrinsic than proptin microplastics, in macrophages, a finding that suggests that in the future The work of observing the effect of microplastics is required under actual – conditions with microplastics found in the environment – not new plastics tested in the laboratory.
The authors also state that prior research has shown that different types of pollutants have different effects on plants and animals – many of these effects pose considerable risks to human health. But such findings are known only because scientists did research. Sadly they note, the same fraction of effort has not yet focused on the potential health effects of microplastics. They point out that not only do medical scientists not know what microplastics can be to people around the world, they also do not know how much microplastics are in the human body.
Researchers further comment that the possible health risks of microplastics can be more difficult to determine than other pollutants due to the different types of plastics involved and the size of particles that can air in different parts of the body. They conclude that due to the amount of microplastics in the environment, it is important that scientists begin to study their effects on humans.
