DESCRIPTION:Speaker: Thorsten Hüffer\nhosted by Sustainability Office\nAbs
 tract: Tire wear is a widespread source of rubber particles and associated
  chemicals in the environment. As particles move from roads into soils and
  waterways\, tire additives can leach and transform\, creating exposure pa
 thways that extend beyond the particles themselves. This lecture will foll
 ow these chemicals from their release during tire wear to their fate in th
 e environment\, focusing on how soil properties\, chemical behavior\, and 
 plant uptake shape potential exposure through food.Drawing on laboratory s
 tudies\, soil-based experiments\, and measurements in commercial leafy veg
 etables\, I will discuss the uptake and transformation of rubber-associate
 d chemicals. The findings show that exposure depends on the compound and r
 oute of entry: some chemicals can be taken up by edible plants\, while tir
 e-wear particles may act as a continuing source of certain additives in so
 il. Detections in vegetables indicate a potential dietary pathway\, but do
  not by themselves establish health effects.The lecture will also consider
  what this evidence means for assessing the environmental footprint of rub
 ber products. Evaluating alternatives requires looking beyond particle emi
 ssions to include additive composition\, chemical release during use and w
 eathering\, and the movement of released compounds through soil\, water\, 
 and food systems.
