SWSteffen WeyrauchBSBettina SeiwertMVMilena Voll

Key Points

  • Aging processes resulted in substantial loss of extractable chemicals from tire wear particles, highlighting environmental degradation.
  • After 17-20 months, transformation products were found among tire wear particles, indicating significant chemical changes.
  • Field study conducted in a sedimentation pond provides insights into the environmental aging of tire wear particles.
  • Considerable residues of extractables remained, suggesting ongoing environmental impacts from tire wear particles.

Abstract

A 17–20 months aging of TRWP by sunlight and in a sedimentation pond shows pronounced loss of extractable chemicals and changes in composition, from parent compounds to transformation products. But considerable residues of extractables remained.
