Engr. Melvin Dapitanan, focal person of the Davao City Airshed Governing Board says that since Davao City’s air quality is at “good and fair” levels for the years 2013-2016, they will measure the air quality again after three years. Dapitanan says the data from the previous years could not be compared because an older standard of measurement was used. (Paulo C. Rizal/davaotoday.com)
