Microplastics and nanoplastics (MNPs) are emerging as a potential risk factor for cardiovascular disease in preclinical studies. Direct evidence that this risk extends to humans is lacking.

When more than one type of pollution gets wrapped up in the same space, the result can be pretty darn yucky—not to mention dangerous. And the gobs scientists discovered recently on the beaches of the typically picturesque Canary Islands certainly fits the bill.

Microplastics are deposited in river floodplains and carried down to deeper levels, according to a study published in the journal Science of the Total Environment. Local topography, frequency of floods, and soil characteristics can affect the amount of plastic particles that are deposited and potentially carried into deeper soil.

En mars 2022, des scientifiques ont confirmé pour la première fois avoir trouvé des microplastiques dans le sang humain. Ces minuscules fragments se trouvaient dans 80 % des 22 personnes testées - qui étaient des membres ordinaires et anonymes du public. L'échantillon était de petite taille et il n'y a pas encore eu de confirmation explicite que leur présence cause un préjudice direct à la santé humaine, mais avec plus d’études, le temps le dira. Les microplastiques font l'objet d'un examen approfondi. Partout où nous les cherchons, nous les trouvons.

The term 'microplastic' was coined just 18 years ago, but already they seem to be just about everywhere. Each year, the average human consumes an estimated 74,000 particles of plastic with unknown health effects. In March of this year, scientists announced they'd found microplastics flowing through our very veins.
