Pak J Med Health Sci Jan ;13(4):844-7.

Aim: Measurement of various particulate matter levels in some areas of Lahore and to ascertain if they are within the world recommended levels. Study design : This was a cross sectional study to measure the particulate matter concentration in 24 hours. Place and duration : The study was conducted in Lahore at various areas which were logistically convenient to the authors. Methodology : A monitoring electronic device was used to measure PM 2.5, PM 1 and PM 10 in some areas of Lahore. Results : The average concentration of all particulate matters measured were very high beyond the levels recommended by the WHO. Conclusion : All the measured particulate matters concentrations in Lahore were too high (average PM2.5 -79.43 μg/m3) as compared to the WHO recommended levels (25 µg/m3 ) in a 24 hour period and can predispose to serious respiratory and cardiovascular diseases.
