One year ago, Hanoi became the first city in Vietnam to measure in real-time its air quality. Thus, Environnement S.A Group has provided the city’s pollution monitoring network with data generated by the 10 AQMS stations installed, being centralized and published online on the Government’s website http://moitruongthudo.vn/ The page provides AQI (Air Quality Index) over the last 24 hour period as well as pollutant concentration for each station.

The air-pollution in Hanoi is a long-lasting problem. The Government already raised warnings about the air quality of the capital city in 2004, when all pollutants measured went beyond safe limits. Hanoi’s pollution at the time was considered as bad as in New Delhi and Karachi, two of the 10 most polluted cities in the world. Especially with exceeding concentration of fine particles and ozone, causing adverse health effects, thus increasing the number of people suffering from severe respiratory and mental health damage from air pollution.

The People’s Committee of Hanoi (CPH) has therefore decided to take important initiatives aimed at improving the “quality of the urban environment”. As part of the “Partnership Agreement (MoU) for the improvement of air quality in Hanoi”, signed by the Embassy of France and the CPH in April 2016, AFD mobilized a subsidy on FERC Fund (Study and Capacity Building Fund) to finance an expertise for the dimensioning and optimization of the air quality measurement and control network.

The expert designated was  Airparif, a non-profit organization accredited by the Ministry of Environment to monitor the air quality in Paris and the Ile de France region (the capital city region). Hanoi’s air quality monitoring network has been defined in partnership with Environnement S.A, French manufacturer and leading provider of online monitoring solutions for the environment, with over 35 000 monitoring systems measuring and reporting the pollution of cities worldwide: Rio de Janeiro, Istanbul, Barcelona, Seoul, Mecca, Delhi, Moscow, Paris, Budapest, Bombay, Abu Dhabi, Bangkok, Dakar, Beijing, Chongqing…Vietnam_AQMS_pollution_monitoring_network

The solution installed in Hanoi has been completely provided by the Group and includes 2 reference pollution monitoring stations measuring gases Ozone (O3), Carbon Monoxide (CO), Sulfur Dioxide (SO2), Nitrogen Oxides (NO, NO2, NOx), Particulate Matter (PM 2.5 and PM 10), as well as 8 Cairpol sensor-based microstations to measure NO2, CO and particulates. All 10 stations being equipped with data acquisition & handling systems, the measured parameters are automatically transmitted to the central server, where the XR® software ensures the supervision and data management. The XR calculates (data scaling, correction, linearization, normalization) and aggregates the resulting data over different time periods. It also follows-up and controls all measuring devices (analyzers, data acquisition systems, meteorological sensors, calibrators, communication systems…) with multi-window representation for data display (raw, means, trends, graphs…), real-time graphic followups, interactive set-up, calibration & automatic results monitoring, remote testing of interfaces, etc…

Major event for the city, the Network’s inauguration has been widely covered by the local and international media, as well as on the National television VTV :http://vtv.vn/video/van-de-hom-nay-19-01-2017-198534.htm

Hanoi cooperates with France to improve air quality 

The Hanoitimes – On Oct 17, Chairman of Hanoi People’s Committee, Mr. Nguyen Duc Chung welcomed the Extraordinary and Plenipotentiary Ambassador of France in Vietnam, Mr. Bertrand Lortholary. Ambassador Bertrand Lortholary affirmed, based on the long-term relationship between France and Vietnam, the desire to expand cooperation with Hanoi capital, especially in the field of environmental protection and air quality improvement.

One of the typical projects in this field is the “Technical Assistance Project for Assessing the Air Environment Status in Hanoi City” signed between the Consultant- AirParif Agency (France) and the Hanoi Department of Natural Resources and Environment in 2016. In which, non-refundable ODA from Funds for Expertise and Capacity-Building (FERC) of the French Development Agency (AFD) enabled  this project in Hanoi with 10 air monitoring stations to be put into operation in 2016.

During the meeting, representatives of Airparif organization reported preliminary results of the project after one year of implementation. Director of this organization, Mr. Frederic Bouvier said that the research process is aimed at overall air quality monitoring and is expected for the cooperation and support of the Hanoi government in the next phase of the project.

With the initial results of the project, Chairman of Hanoi People’s Committee affirmed that this project is effective and practical. Based on the results, Hanoi will develop an appropriate program to improve the air quality.
Recognizing the efforts as a research consultancy unit, Chairman of the City People’s Committee wished Airparif will actively evaluate to overcome, upgrade the unqualified air monitoring station as well as supplement and improve the air quality. Accordingly, the Airparif shall provide mobile devices to easily identify regional air quality as well as plans to integrate all data for convenience for residents and visitors. Most importantly, on the basis of the research results, the organization will propose solutions to purifying air at the monitoring station. By the way, Chairman of the City People’s Committee also expects to receive support from the French Embassy for the project to be completed in 2018 as well as to receive support for the training of personnel operating the monitoring system.

Thanks to the cooperation of the Hanoi government, Ambassador Bertrand Lortholary acknowledged the proposals from Chairman of the City People’s Committee and affirmed that efforts will be made to create conditions for cooperation between France and Hanoi in particular and Vietnam in general in the coming time.In September, Green Innovation and Development Centre (GreenID), a Hanoi-based NGO, released a report on air quality in Vietnam in the first half of this year. It compared air quality in 2017’s first six months and in the same period of 2016.
Based on the report, from January to June, Hanoi suffered 139 days of excessive PM2.5 level, according to international standards. PM, or particulate matter, is a mixture of solid particles and liquid droplets in the air. PM2.5 particulates are about a thirtieth as thick as the width of a human hair and can pass through lung tissue and into the blood, harming human health. The data showed no relation between the concentration of pollutants and peak traffic hours, meaning air quality has been affected by different pollution sources, notably the energy industry.
Nguyen Thi Anh Thu, GreenID’s environment expert, said that though the air quality has improved, millions of Hanoians rarely enjoyed fresh air. The Hanoi People’s Committee in January launched an online service with information about weather conditions and environment indexes, including air quality index, rainfall and flooding.”
