Hà Nội (the capital of Vietnam): Hà Nội was named as the most contaminated city on the planet, with Hồ Chí Minh City not far behind.

Figures publishedby the air quality screen application AirVisual put Vietnam's capital city at the highest position on the list followed by Jakarta in Indonesia and Hồ Chí Minh City, taking the second and third places.

The fundamental cause for Hồ Chí Minh City’s contamination is the trapped dust. According to the Institute for Environment and Resources under the National University – HCM city, the brown smog here is mainlybecause of the elevated level of fumes exhaustedfrom vehicles, industrial factory and Indonesian forest fires. In any case, the Center for Natural Resources and Environment Monitoring rejected the news.

Numerous provinces in the Red River Delta additionally experienced air contamination. The most contaminated areas are Thai Binh, Hung Yen and Nam Dinh. Straw burningis accused for causing contamination since the most contaminatedoccasions are during the early morning and night. The most contaminated areas are in suburbs. Fine dust contamination is a serious issue in Hà Nội. The Green Innovation and Development Central's air report a year ago demonstrated that the fine dust concentration in Hà Nội was 40.1 micrograms per cubic meter, a lot higher than the national standard of 15 micrograms for every cubic meter. Be that as it may, contamination from June to September is frequently brought about by straw burning activities.

On September 25, Hà Nội's pollution index topped the 200, which mark is viewed as unsafe. In spite of the fact that the air quality somewhat improved, Hà Nội’s recorded air quality is still among the most awful places on the planet. Awful climate in the capital and smog made it hard for the dust to be diluted or blown away. Also, low wind speeds reduceair convection and trapping dust close to the surface all added to the declining quality of the air in Hà Nội.

Under this situation, a type of mask called N925 is launched and considered the best dust filter to protect people’s health. Unfortunately, it is a temporary solution. If we want to solve this problem thoroughly, we need to raise awareness of environmental protection because:
