IER comprises of one environmental monitoring station which is one of the three main mainland stations (approved by MOSTE and MOET) of the National Environmental Monitoring System. Our station is responsible for monitoring and reporting environmental changes in Ho Chi Minh City and MeKong Delta Provinces (Station III).
In addition, IER also monitors and analyzes water quality for Saigon-Dongnai river system and traffic pollution monitoring program in Ho Chi Minh City.

Environmental pollutants and parameters being monitored:
• In surface water: pH, temperature, TDS, EC, SS, DO, BOD5, N-NH3, N-NO3, turbidity, Fe2+, Cl-, SO42-, PO43-, oil, grease and coliform.
• In the atmosphere: SPM, CO, NOx, SO2, VOC, lead and noise.
• Solid waste: its expressed composition as a percentage, density, humidity, generated solid waste, collected solid waste, collection means, treatment methods, location and area of open refuse dumps.

Through Vietnam-Switzerland cooperation project, IER is monitoring toxic pollutants in water and sludges of SaiGon-Dongnai river system and also air pollutants in the atmosphere, determining their sources and recommending the solutions.

Main parameters being analyzed
• Heavy metals: Cu, Pb, Zn, Cr, Ni, Cd, Hg,...;
• Pesticides: BHC, p-p'DDD, p-p'DDT, p-p'DDE;
• PCBs, PAHs (in both aquatic and the atmosphere).

Environmental quality monitoring results are usually recorded and presented in reports issued regularly: 矵
• Report on synthetic results of National Environmental Monitoring Station III (Ho Chi Minh City and MeKong Delta Provinces) in 1995, 1996, 1997, 1998, 1999, 2000, 2001;
• Report on results of water quality monitoring of SaiGon-DongNai river system (1996,1996);
• Report on results of traffic pollution monitoring in HCMC in 1995-2001;
• Primary Report on results of special pollutants monitoring: heavy metals and pesticide in water and sludge of SaiGon-DongNai river system.
