Air Pollution in Hanoi: Projections for Persistence Through Early Next Year
Recent analyses indicate that air pollution in Hanoi is likely to continue worsening through the winter months, with projections extending until the end of March next year. Meteorological experts highlight a concerning trend based on historical observations over recent years.
Current Air Quality Situation
The current air quality in Hanoi has shown little to no signs of improvement, with residents experiencing dense and polluted air, a phenomenon increasingly common in the capital. Monitoring systems reveal that air quality is alarmingly poor, particularly affecting vulnerable populations such as the elderly, young children, and individuals with pre-existing respiratory conditions.
Numerous locations in Hanoi have recently registered air pollution levels classified as hazardous, with the Air Quality Index (AQI) reaching values between 153 and 222, indicating a purple level of pollution. Despite the recent rainfall, which typically aids in clearing airborne pollutants, air quality is expected to remain compromised.
Seasonal Trends to Air Quality Decline
Dr. Hoàng Dương Tùng, chairman of the Việt Nam Clean Air Network, observed that air quality in Hà Nội tends to deteriorate during the winter months.
In this season, emissions and fine dust are less likely to disperse, leading to accumulation in low-lying areas. Additionally, pollution from traffic and construction continues to contribute to the problem. As a result, air pollution may persist until early next year.
Typically, the air pollution season lasts from October to the end of March. During dry spells with little wind, fine dust (PM2.5) can spread extensively, according to the expert.
Health Risks from Poor Air Quality
Poor air quality can make breathing challenging, trigger coughing, and lead to chest tightness, among other respiratory issues. Individuals with respiratory conditions should limit outdoor activities when air pollution levels are elevated.
For asthma patients and those with chronic obstructive pulmonary disease (COPD), it's crucial to adhere to prescribed daily medication regimens. If symptoms like discomfort or shortness of breath occur, it may be necessary to adjust the dosage of bronchodilators as directed by a healthcare provider.
Monitoring Solution - AirVisual Pro
To better understand and manage air quality, tools like the AirVisual Pro monitor can be beneficial. This device measures PM2.5 and CO2 levels, along with temperature and humidity, providing real-time data that can be accessed via a smartphone. When combined with the AirVisual Outdoor monitor, users can compare indoor and outdoor air quality, helping to make informed decisions about health and safety during pollution episodes.
As Hanoi prepares for the winter months, addressing air pollution will be critical to safeguarding public health and improving overall quality of life.
