As of 9:00 AM on January 10th, the following areas recorded air pollution levels at monitoring stations: At the monitoring station near the Parabol Gate of Hanoi University of Technology on Giai Phong Street (Hanoi), the index was 182; at the monitoring station on Hung Vuong Street, Thai Nguyen Province, the index was 153; at the monitoring station on Street No. 106, Tran Hung Dao Street (formerly Hai Duong City People’s Committee), the index was 168; at the monitoring station on Thai Binh Bridge, Tran Thai Tong Street (formerly Thai Binh Province), the index was 184; at the monitoring station at No. 437, Nguyen Van Linh Street, Hung Yen Province, the index was 199; and at the monitoring station at Giang Thep Stadium, Thai Nguyen Province, the index was 199.
The provinces and cities with poor air pollution levels measured at the following stations are as follows: At the Nhan Chinh – Khuat Duy Tien Park station, the index was measured at 142; at the inter-agency area station in the former Bac Giang province, the index was measured at 138.
Additionally, at the monitoring station of the former Ministry of Natural Resources and Environment complex at 20 Ly Chinh Thang Street, Ho Chi Minh City, the reading was 113; at the monitoring station at the intersection of Le Huu Kieu and Truong Van Bang streets, the reading was 106; and at the monitoring station on Huyen Tran Cong Chua Street, Vung Tau province, the reading was 109.
Previously, on January 5th and 7th, the air pollution index in Hanoi and some other provinces and cities was at bad and poor levels.
Health experts advise that during peak pollution days, people (especially the elderly, young children, and those with respiratory illnesses) should limit going outside. If travel is unavoidable, people should wear masks that meet PM2.5 filtration standards and wear them correctly (fitting snugly against the nose, leaving no gaps).
At home, people should keep doors and windows closed, use air purifiers, regularly clean their noses and throats, and maintain a nutritious diet to boost their immune system.
According to guidelines from the Ministry of Agriculture and Environment, air pollution in Hanoi and surrounding provinces directly affects socio-economic activities and public health.
To proactively control, prevent, and minimize the level of pollution and adverse impacts of this pollution episode, the Ministry of Agriculture and Environment requests the People’s Committees of Hanoi, Hai Phong, Bac Ninh, Hung Yen, Phu Tho, Thai Nguyen, and Ninh Binh provinces and cities to focus on directing and decisively implementing measures to strengthen street cleaning and reduce road dust: directing environmental sanitation units and owners of infrastructure construction projects to immediately increase the frequency of street sweeping and dust removal.
Provinces and cities are strictly controlling dust emissions from construction and transportation activities: directing the Department of Construction, commune/ward police, and local authorities to strengthen inspection and supervision of construction sites in their areas; strictly managing industrial emissions and activities involving burning in craft villages; controlling the stable operation of exhaust gas treatment systems, ensuring compliance with environmental technical standards; encouraging a reduction in operating capacity on days when air quality (VN_AQI) is at a poor level or worse, affecting people’s health; and thoroughly controlling the burning of agricultural waste and by-products.
In addition, provinces and cities are strengthening public health information and warnings: directing the Department of Agriculture and Environment and the Department of Health to coordinate with local media and press agencies to continuously update information on air quality and monitor the VN_AQI index on the VNAir application.
The Air Pollution Index (EPI) defines air quality based on a scale from 0 to 500, classified into six levels with corresponding colors and health warnings. These levels include: Good (0-50, green), Moderate (51-100, yellow), Unhealthy for sensitive groups (101-150, orange), Unhealthy (151-200, red), Very unhealthy (201-300, purple), and Hazardous (above 300, brown).
