Some people said that this phenomenon has appeared for many consecutive days, causing an uncomfortable feeling. Mr. Nguyen Van Hoa (residing in Thu Duc ward) shared: "Every morning I drive to work early, the fog has become much thicker in the past few days. Seeing the clear sky like usual, the air is heavy, it feels like there is fine dust.
According to the air monitoring application Air Visual (under IQAir, Switzerland), air quality in Ho Chi Minh City at 8am is at a sensitive level, with an AQI of 117. The PM2.5 fine dust concentration was measured at 42 μg/m3, about 8.4 times higher than the average annual guidance value of the World Health Organization (WHO).
