Photo: Quang Khai/Tuoi TreHo Chi Minh City’s environment department has proposed the city spend US$3.5 million on a new air quality monitoring system to replace an obsolete one. Air quality in the city now is now measured by a semi-automatic system that operates between 8 a.m. and 9 a.m., and between 3 p.m. and 4 p.m. Tests by the environment department released late last year found air pollution in the city has worsened. Vehicles, especially motorbikes, have been identified as a major cause of air pollution in the city, the most crowded in Vietnam with 12 million people including migrants.
