Despite the air quality in many central and southern localities showing signs of improvement, several northern provinces saw elevated levels of air pollution on September 3, that could seriously impact human health.
Monitoring app AirVisual of IQAir, a Swiss air-quality technology and monitoring company, recorded nine red points at around 8 a.m. this morning in Hanoi capital, Hung Yen, and Lang Son. This means that the overall air quality is beginning to negatively affect normal people’s health and badly impact the health of sensitive groups.
The main areas of Hanoi that suffered from high air pollution levels included To Ngoc Van street in Tay Ho district and Gia Thuong street in Long Bien district.
Meanwhile, independent air quality tracker PAMAir reported that the AQI at several air monitoring stations located throughout Hanoi and neighbouring areas was at orange, indicating that the overall quality of air was at a harmful level for human health.
Monitoring app VN Air produced by the Ministry of Natural Resources and Environment showed that four points in Hanoi and Bac Ninh province remained at average levels.
Environment experts have therefore advised people to refrain from any outdoor activities, close windows, and use facemasks when going outside amid periods of low-quality air, along with the threat of the COVID-19 pandemic.
Public green spaces have never been more important in Hanoi, a densely populated city facing challenges from rapid urbanisation, climate change and air pollution.
