The air pollution situation in Hanoi and surrounding areas

Air pollution occurs throughout the country, but is most evident and continues for a long time in Hanoi capital and neighboring areas in the Northern Delta region. Since September, the AQI (short for air quality index) when measured at many points in this area, as recorded by the PAMAir system, has been at the threshold of serious pollution (AQI above 150). This is the level of danger to human health.

Even without monitoring the AQI, people living in the above areas are also clearly aware of the air pollution. Although it was morning, but the air was cloudy, looking far away blurred, looking up at the sky, the sky was originally dark blue, now only a pale blue color is visible. Dirt dust makes even pedestrians wear dust masks. Across the city, faces were sealed everywhere, filled with fatigue and anxiety.

The dangers of air pollution to human health

Air pollution in Hanoi and surrounding areas is classified as fine and super fine dust. This type of dust has a very small size, less than 2.5 micrometres in diameter, so it is called PM2.5. Because they are small, they are suspended in the air and can creep into doorways. So even if the door is closed, we can still breathe in fine dust.

Fine dust can pass through the medical mask

If the dust is large, the coarse dust can be filtered with a mask, then the fine dust is not. They easily penetrate conventional masks and because of their small size, they also pass through the filtration system of the respiratory system, into the circulatory system. Once in the body, they can cause respiratory and cardiovascular problems such as chest pain, chest tightness, cough, nose pain ...

Some solutions to protect health against fine dust pollution

Monitoring the situation of fine dust pollution every day

Every day, you should monitor the fine dust pollution where you live. If exceeding the safety level, limit going outside or equip yourself with a coat, hat, dust masks… You can track through websites providing pollution situation such as Aqicn.org, moitruongthudo.vn, Pamair.org, Air Visual…

Do not use medical masks

Regular medical masks and masks in this case are useless because they have a lot of gaps, making it easy to pass through small dust like fine and super fine dust. You should use a special mask like activated cacbon gauze mask - can block fine dust and absorb toxic gases in the surrounding environment, or use a mask that is advertised as able to filter fine dust.

Use an activated carbon mask or a filter that filters out fine dust

Buy an air purifier for the house

Your home should be a safe haven when it's filled with pollution outside. You should have an air purifier, at least in your bedroom. A good air purifier not only helps filter dust and fine dust, removes harmful impurities, but also measures fine dust concentration in the air, helping you proactively update information at all times.

Air pollution has become a problem globally, not just in the North. The time has come to equip ourselves with the knowledge and supplies necessary to protect the health of ourselves and our loved ones. Remember, always wear dust masks before going out!

The air pollution situation in Hanoi and surrounding areas

Tình trạng ô nhiễm không khí diễn ra khắp cả nước, nhưng thấy rõ nhất và tiếp diễn trong thời gian dài là tại thủ đô Hà Nội và các vùng lân cận thuộc khu vực đồng bằng Bắc bộ. Từ tháng 9, chỉ số AQI (viết tắt của chỉ số chất lượng không khí) khi đo ở nhiều điểm tại khu vực này, theo ghi nhận của hệ thống PAMAir, đã ở ngưỡng ô nhiễm nghiêm trọng (AQI trên 150). Đây là mức gây nguy hiểm đến sức khỏe con người.

The dangers of air pollution to human health

Ô nhiễm không khí ở Hà Nội và các vùng lân cận thuộc loại ô nhiễm bụi mịn và siêu mịn. Đây là loại bụi có kích thước rất nhỏ, đường kính dưới 2.5 micromet nên được gọi là PM2.5. Vì nhỏ nên chúng bay lơ lửng trong không khí và có thể len lỏi vào các khe cửa. Nên dù đóng kín cửa, chúng ta vẫn có thể hít phải bụi mịn.

Fine dust can pass through the medical mask

Nếu các loại bụi to, bụi thô có thể lọc được bằng khẩu trang thì bụi mịn lại không như vậy. Chúng dễ dàng xuyên qua các loại khẩu trang thông thường và vì kích thước nhỏ nên chúng cũng lọt qua hệ thống lọc của hệ hô hấp, xâm nhập vào hệ tuần hoàn. Một khi đã đi vào cơ thể, chúng có thể gây ra các vấn đề về hô hấp và tim mạch như đau ngực, tức ngực, ho, đau mũi…
