Tap water contains microplastics, according to a study

There are two categories of microplastics: the primary is produced as a direct result of the human use of these substances and the secondary as a result of fragmentation of plastic waste of larger portions. Microplastics come from different sources: they are found massively in products such as cosmetics, personal care and household products, in building materials, in industries and in agriculture.

According to an investigation launched by Orb Media, a nonprofit organization in Washington, which shared the results with the Guardian, the water coming out of taps around the world contains microscopic plastic fibers. The dossier, called Invisibles: The Plastic Inside Us, represents the first global study on the pollution of drinking water by microplastics.

The United States has been identified as the country with the highest contamination rate: values ​​that reach up to 94%, with fibers found in tap water also sampled in the buildings of the United States Capitol, at the headquarters of the Agency for the Protection of the United States.

'Ambiente and even in the Trump Tower in New York.

Followed by countries such as Lebanon and India. European nations such as the United Kingdom, Germany and France have a lower contamination rate, even if the presence was found in 72% of cases.

As regards the concentrations detected, the average number of fibers in half a liter varies from 4.8 units in the United States to 1.9 in Europe. It is a contamination distributed more or less evenly in every part of the globe, regardless of the place of supply.

Franco Borgogno, journalist, tutor and researcher at the European Research Institute, has been collecting data since 2015 on the presence of microplastics and macroplastics in the global ocean. Participating in 2016 in the HighNorth oceanographic campaign, controlled by the Italian Navy, and conducted in the sea surrounding the Svalbard Islands, in the deep Arctic and at the Northwest Passage, he identified microplastics in the extreme Arctic sea.

Microplastics are also contained in the air, according to some studies on the highest peaks in Italy every year millions of microplastic particles fall which, at the end of winter, when the snow has melted, they end up in the waterways.
