The work of American researchers, published this Wednesday, shows that the simple contact of water with these particles produces toxic chemical compounds. It is the first time that such a phenomenon is highlighted for this material mainly made from petroleum.
An investigation identifies a chemical mechanism that helps explain the harmful effects of these particles on the body
The world stands on many premises. One of them is that plastic is a "chemically inert" material. That is, that it does not react with the substances in its environment and that, therefore, we can use it without fear that it triggers unexpected chemical reactions. Under this idea, for decades we have used this material to manufacture all kinds of objects, from children's toys to kitchen utensils and food containers. We have even assumed that, alt…
Intrinsic physicochemical activity at microplastic–water interfaces
Plastics have become an integral part of our modern society, largely because they are generally regarded as chemically inert under normal circumstances. However, plastics fragmented into microplastics (less than 5 mm in size) have recently raised significant public concerns, and have been detected widely across ecosystems and human tissues with increasing environmental and health risks1–5. Here we show that commodity microplastics exhibit intrin…
