Miền Bắc ô nhiễm không khí nghiêm trọng trong 10 ngày tới | VTV24

Key Concepts:

• Air pollution in Hanoi
• Hồ Tây (West Lake) as a location with good air quality, but still affected by pollution
• PM2.5 (fine particulate matter)
• Temperature inversion (nghịch nhiệt)
• Lack of wind (lặng gió)
• Dense fog (sương mù dày)
• Reduced pollutant diffusion
• Government measures to control air pollution
• Street cleaning and dust reduction
• Construction site dust control
• Industrial and agricultural emission management
• Low-emission zones (vùng phát thải thấp)
• Mist spraying systems for dust suppression
• Drone and satellite monitoring for open burning
• Public health recommendations

Summary:

Air Quality Concerns in Hanoi and Mitigation Efforts

Despite Hồ Tây (West Lake) being recognized as an area with relatively fresh air and good air quality in the capital, individuals like Mr. Trình, who regularly exercise there, still need to wear masks due to increasing air pollution. Mr. Trình notes, "Although this West Lake is very airy and cool, in reality, the pollution is still very heavy. Usually, its PM2.5 is very dusty, fine dust that affects people's health, especially the elderly."

Factors Contributing to Worsening Air Pollution

In the coming days, Hanoi and surrounding provinces are expected to experience temperature inversion, calm winds, and dense fog. These meteorological conditions will significantly reduce the ability of pollutants to disperse, potentially making the air pollution situation more severe than in previous years.

Government and Local Authority Responses

To proactively control and minimize air pollution levels, the Ministry has directed localities to intensify street cleaning and implement measures to reduce road dust. This includes using specialized vehicles to spray water and wash roads along major transportation routes and urban gateways. Strict control over construction activities, increased inspection and monitoring of construction sites, and management of industrial and agricultural emission sources are also emphasized.

In response to these directives, Hanoi City is implementing several solutions. The city is piloting "low-emission zones" as a measure to reduce air pollution from transportation. Furthermore, there are plans to advise the city to require construction projects to install mist spraying systems to suppress dust during construction.

Monitoring and Public Health Recommendations

Over the next 10 days, the Ministry of Agriculture and Environment will utilize drones and satellite imagery to monitor and detect open burning and significant emission sources contributing to air pollution.

Given the persistent air pollution, the Ministry of Agriculture and Environment has issued recommendations for the public. Citizens are advised to regularly monitor air quality indices and limit outdoor activities during periods of high pollution, particularly for the elderly, children, and individuals with underlying respiratory conditions. If going outdoors is necessary, wearing a mask is recommended for health protection.
