Tiny particles increase in air with ethanol-to-gasoline switch

The concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of São Paulo, Brazil, when higher ethanol prices induced drivers to switch from ethanol to gasoline, according to a new study. The research team also found when drivers switched back to ethanol because prices had gone down, the concentration of ultrafine particles also went down.
