Air Pollution Measurements are Carried out at Metro.

Air Pollution Measurements are carried out at Istanbul metros and results are below limit value.
Istanbul Metropolitan Municipality affiliate Metro Istanbul carried out PM 2.5 and PM 10 measurements to measure air quality at stations and inside carriages under its operation.
