From the road to the plate: lettuce takes up toxic additives from tyre wear


Wind, sewage sludge, and waste water carry tyre wear particles from roads onto farmland. A new lab study shows: The pollutants contained in the particles could get into the vegetables grown there. Researchers at the CMESS and PLENTY have investigated whether chemicals released from tyres find their way into lettuce plants and could ultimately end up on our plates. Their analyses showed: The lettuce took up all the compounds studied - some of them highly toxic. Further investigations are to show how this process actually takes place in arable soils. The study has now been published in the international journal Environmental Science & Technology.
