Summary

Tire particle chemicals found in 60-100% of human urine samples.
6PPD-quinone, a toxic byproduct, is a common pollutant.
Tire particles are a major source of microplastic pollution.

Researchers have detected concerning levels of tire-related chemicals in human urine, indicating a widespread environmental and health issue. A study in South China identified the chemical 6PPD and its toxic byproduct, 6PPD-quinone, in 60% to 100% of urine samples collected from various age groups, including children and pregnant women. This discovery is significant given the known toxicity of these compounds to aquatic life.

These tiny tire particles, derived from fossil fuels, are recognized as a primary contributor to microplastic pollution. Scientists are concerned about the potential long-term health consequences for humans, with previous research linking such pollution to increased risks of cardiovascular disease, cancer, and neurological disorders. The complex chemical composition of tire particles means their full impact may not yet be understood.
