Hundreds of people were evacuated in southwestern Ohio after a train car leaked styrene, a toxic chemical used in plastics manufacturing, sending white vapor plumes into the air.
Amudalat Ajasa and Annabelle Timsit report for The Washington Post.
In short:
- A train car leaked styrene near Cincinnati, leading to an evacuation within a half-mile radius.
- Styrene exposure can cause neurological effects and is considered a carcinogen by California officials.
- Emergency teams worked to cool the railcar while air quality remained under close observation.

Why this matters:
Chemical spills during transport raise serious health and safety concerns for nearby communities. Styrene exposure can cause both short- and long-term health issues, and repeated incidents like these highlight the risks of transporting hazardous materials.
