A team of researchers from Austria You may check that is different Toxic substances from tire wear Of cars carried by the wind and Later lettuce absorbs it and other plants.
Car tires are an important source of Microplastics that pollute the environmentThilo Hoffmann, professor of environmental geosciences at the University of Vienna, says in the study published in the specialized journal Environmental Science and Technology.
Yes good Access It remains particulate emissions from the tires It is not well definedIt is estimated that about one kilogram of tire particles per inhabitant per year is blown into the environment by wind and dumped into rivers and wastewater due to rain, notes the scientist. In this way it also reaches arable soil, as well as through sewage sludge which is used as fertilizer in agriculture.
In a statement, Hoffman’s team made this clear Choose five chemicalssome of them “highly toxic”, to check how vegetables absorb the additives from tire wear.
Sponge lettuce
Our measurements showed that lettuce plants Pick up through the roots all the compounds we have studiedThey transferred it to the papers and collected it there,” scientist Anya Sherman explains in the note.
between articles In lettuce leaves, for example, is the chemical “6PPD chinone,” which has been linked to massive salmon deaths in the United States and is Clearly toxic.
Hofmann had already shown in other studies that potentially harmful chemicals are present in microplastics They are usually released into the upper layers of the soil.
