HÀ NỘI — Air quality in Hà Nội has seen improvement in the first four months of the year, but not in all parts of the city.

Good air quality was recorded at the end of April and the beginning of May at monitoring stations in the districts of Cầu Giấy, Đống Đa and Hoàng Mai, according to the Hà Nội Environmental Protection Agency.

From 10 monitoring stations across the city, concentrations of harmful PM10 and PM2.5 matter decreased by 1.5 and 2 times respectively, compared to the period from November to December 2017.

The air quality index (AQI), which measures daily air pollution, saw a drastic improvement during the Reunification Day (April 30) and Labour Day (May 1) holidays, as well as during Lunar New Year holiday (February 16-21) compared to regular days due to lower traffic in the city.

However, bad air quality was still recorded at monitoring points near major roads, especially on Minh Khai Street (part of National Route 32) and from Phạm Văn Đồng Street to Thăng Long Bridge. Particulate matter concentrations in these areas sometimes exceeded the permitted level, while their AQI often remained around average.

Measurements of air pollution in a recent report from the Green Innovation and Development Centre (GreenID), a Vietnamese not-for-profit organisation, have also worried people. It categorised Hà Nội’s air quality in the first three months of the year as “bad” for people’s health.

While the report somewhat reflects reality, officials from the Hà Nội Environmental Protection Agency said that those measurements do not represent the entire city because they were recorded near the Láng Hạ-Đê La Thành intersection where there is always heavy traffic.

Air quality in Hà Nội is not as bad as what was written in the report, they said, adding that Việt Nam’s official method of measuring AQI (issued by the Ministry of Environment and Natural Resources) is different to GreenID’s which follows the US’s environmental standards.

Amidst worries about the city’s air quality, environmental experts said that the city should try harder to get its observation data as accurate as it can in order to make better forecasts.

Aware of this, Lê Tuấn Định, deputy director of Hà Nội’s Department of Environment and Natural Resources, said that 70 more air monitoring stations will be installed across the city in the coming time.

“The city is applying several measures to improve its air quality, including reducing the number of motorbikes, limiting the use of honeycomb charcoal stoves for cooking, and growing more trees,” he said.

Nguyễn Đức Chung, chairman of the Hà Nội People’s Committee on Monday, told the department to make public all information about the city’s air quality.

“We should keep people posted about the quality of air where they live on a daily basis, and highlight the reasons for it and solutions to improve it,” he said.

Action month on environment

The capital city is going to hold a series of environmental protection activities in June in response to the Action Month on Environment and World Environment Day, which will take place on June 5.

One notable event is a festival promoting sustainable living, which will take place on June 2 at Lý Thái Tổ Park, near Hoàn Kiếm Lake. Expected to attract 1,000 participants, it features games, exhibitions and activities that focus on promoting the use of environmentally friendly energy sources, recycling, waste collecting, and limiting plastic use.

On June 5, Hà Nội’s Department of Environment and Natural Resources will collaborate with the Việt Nam Fatherland Front to clean up roads, drains and sewers in Tri Thủy Commune in the city’s outer district of Phú Xuyên. About 500 participants are expected to take part in the activity. — VNS
