AIR QUALITY MONITORING IN HOCHIMINH CITY

Background
  • Area 2,093.7 km2. Population 5 million.
    Average population density 2,419 pers/km2
  • Industry 28,500 small-scale industries, 700
    medium/large-scale industries. 10 industrial
    zones 02 export processing zones
  • Over 2,250,000 motorcycles and 175,000 all kinds
    of automobiles
  • Domestic solid waste 5,000 tons/day
  • Hospital waste 07 tons/day collected and treated
  • Domestic waste water 800,000 m3/day not treated
  • ? Air quality is becoming a serious problem as a
    result of the uncontrolled emissions.

Air Quality Monitoring System (AQMS) - Objectives
  • Main objective of AQMS in HCMC is supplying
    precise and reliable data on air quality in Ho
    Chi Minh City to City authority, policy makers
    and public.
  • Aimed subordinate objectives
  • - Monitoring trends of air pollution over time
  • - Establishing a relation between pollution
    source- receptors
  • - Identifying what worst pollutants and how
    their serious level
  • - Evaluating the effects of air pollution
    control programs
  • - Understanding the exposure of population to
    air pollution
  • - Giving database for urban planning, land use,
    transportation planning, preparing environmental
    strategy and policy
  • - Applying in air modeling.

Air Quality Monitoring System (AQMS) - History
  • The end of 1992 The network includes four
    ambient air monitoring stations (PM, SO2, NOx)
    and three stations for roadside monitoring (PM,
    NOx, Pb, noise).
  • In June 2000, the automatically air quality
    monitoring system supported by UNDP DANIDA,
    includes two urban background stations (monitor
    PM10, SO2, NOx, CO, O3), two roadside stations
    (monitor PM10, NOx, CO, O3 ), were installed.
  • In Nov 2002, more new five automatically air
    quality monitoring stations were installed by
    NORAD support, includes three urban background
    stations (monitor PM10, SO2, NOx, O3), two
    roadside stations (monitor PM10, NOx, CO, O3 ).

  • Monitoring data and
  • Air Quality Index
  • are presented on City-Web, public electronic
    board

  • Conclusion Remarks
  • Result
  • Dust (TSP, PM10) and CO have been the most
    serious pollutants in roadside air
  • Concentration of pollutants have a increasing
    trend basing on the urban development
    (transportation, building, population), if not
    performing any improvement.
  • Data shows lead concentrations in roadside air
    reduced substantially and lower WHO standard
    after using unleaded gasoline. In results, public
    health gains benefit
  • Constrains
  • - Lack of man power, professional knowledge and
    experiences
  • - Difficulties in maintenance and repair
    instruments
