Microplastics, i.e. small pieces of plastic of microscopic size resulting from plastic pollution, can be transported through the air by the wind and even for very long distances until they pollute areas that at least apparently seem immaculate because they are not frequented by human beings.
This is confirmed by a new study that appeared in the periodical Earth-Science Reviews that analyzes the current state of the so-called “atmospheric microplastics”.
The detection of considerable quantities of microplastics, plastic particles with a size ranging from 100 nanometers to 5 mm, has come on several occasions in recent years so that very often have made news findings of generous amounts in places such as mountains or deserts, very far from population centers.
The research group led by Shichang Kang of the Chinese Academy of Sciences, examined the current state of knowledge on atmospheric microplastics and highlighted the impact that these can have on the global environment when deposited in remote areas.
With this further study, microplastics are probably definitively recognized as air pollutants and another type of particulate matter.
“The current research on atmospheric microplastics is in its early stages and therefore suffers from insufficient comparable data on abundance and characterization”, the researchers report that further research, with more standardized methods for sampling and measurement, should be carried out in the future to really understand the level of severity of this type of pollution also in relation to direct exposure with humans.
