Air quality worsens as thick haze descends on Hanoi capital
VOV.VN - The air quality in Hanoi sharply declined on the morning of March 8 to reach extremely unhealthy levels, exemplified by a thick layer of haze that is currently blanketing the capital.
Hanoi’s Air Quality Index (AQI) stood at between 156 and 159 at 8:30 a.m. on March 8, according to several air monitoring stations located throughout the city.
Most notably, the AQI was recorded at the hazardous level of 159 on Hang Dau street, while the air quality at Hanoi Children's Palace was measured at 156. Elsewhere in the capital, the AQI was at 154 on Cau Dien street, 153 on Thanh Cong street, and 152 on Pham Van Dong street. In addition, the air quality around the outskirts of the capital remained at low and average levels.
Worryingly, AQI levels above 100 are widely considered to be unhealthy. This means children, seniors, and others suffering from heart or lung problems should remain indoors, whilst local citizens have also been advised to don masks and protective eyewear in an effort to reduce exposure to pollutants.
According to health experts, haze and high humidity serve to limit air circulation, thereby causing air pollutants to stick at lower altitudes and slowly decreasing the air quality.
