Air quality in HCM City worsened once again on the morning of June 26 with the air quality index (AQI) rising to 161, a level which is considered to be harmful to people’s health, following an evaluation of monitoring application AirVisual.
A research work on the presence of phthalates in indoor air in northern provinces has been nominated for the 2020 Ta Quang Buu Award.
Investment in automatic air monitoring systems should be a high priority, Hoang Duong Tung, chair of the Vietnam Clean Air Network, has said.
The social distancing policy has minimized emission activities, improving the air quality in Hanoi. However, the activities in the neighborhoods and surrounding provinces still show certain effects on air quality.
The conclusion that economic losses caused by air pollution could be up to 5 percent of GDP has raised controversy.
According to Hoang Duong Tung, chair of the Vietnam Clean Air Network, former deputy general director of the General Directorate of Environment, PM 2.5 fine dust and ozone are the two most worrying issues.
Vietnam has been warned that serious air pollution will affect economic growth in the long term, and lead to foreign investment decline.
Mitigating air pollution in Hanoi is a difficult task as pollutants are spread out in the air with no boundaries. Hanoi alone won’t be able to fulfill the task, scientists say.
The emission sources outside Hanoi make up two-thirds of PM2.5 fine dust concentrations in Hanoi, according to a survey released in October 2018 on quantifying pollution sources.
People have been advised to restrict outdoors exercise, close windows and doors, and wear protective masks to protect themselves from PM2.5 fine dust.
That is a question posed by experts in the context of the high air pollution concentration in Vietnam.
The air quality in the last six days of November was poor, with the index exceeding the permitted levels.
The air quality in Hanoi is becoming worse than usual. In suburban districts, people are burning straw and scraps of fabric though they have been warned of the risks.
