- •
Oxidative activity shows considerable variation between different subway platforms.
- •
Subway PM oxidative potential is not linked to ventilation or tunnel night works.
- •
Highest oxidative potential coincide with PM with higher levels of Cu, As and Sb.
- •
The strongly Fe component in PM subway does not produce any obvious toxic effect.
- •
Lowest oxidative stress was found at station with PSDs.
