New research reveals that microplastics from tires are contaminating crops, raising concerns about food safety.
Virginia Gewin reports for Civil Eats.
In short:
- Vehicle tires, made of synthetic rubber, shed microplastics containing harmful chemicals.
- A recent study found tire additives in 20 out of 28 lettuce samples.
- The exact source of these pollutants in crops remains unclear, but possible routes include biosolids, atmospheric deposition, and recycled irrigation water.

"We don’t know the total chemical burden; that’s left out of the conversation."

Why this matters:
Microplastics from tires can infiltrate our food, potentially posing health risks. The specific chemicals involved, which include various additives and compounds used in tire manufacturing, are known to have adverse effects on human health. Some are suspected endocrine disruptors, while others are linked to cancers and other chronic conditions.
