HCM CITY (VNS) — A thick smoggy carpet has enveloped HCM City's Sai Gon River and others surrounding areas for the past two days causing inconvenience in the flow of the river.

The carpet was suspected to have been caused by environment pollution as hydro meteorological experts said the city and some provinces were suffering from high density of dust and vehicle smoke in the past few days.

It mostly appeared in the early mornings, gradually faded away and ended after noon. Districts of 2, 4, 7, 9, and 12 and streets around Sai Gon River were the most affected.

A resident said when the smog reached its peak at around 7am, it was impossible to have a clear view from either side of the Sai Gon River. Boats sailing across the river were also not visible.

The foggy carpet also covered Thu Thiem, and Phu My bridges, as well as the streets of Pham Van Dong and Nguyen Van Linh.

Deputy Director of the Southern Hydro-meteorological Centre Dang Van Dzung was quoted by vnexpress.net that not only HCM City but other southern provinces had also been affected.

The expert said the fog, which technically occurred since humidity reach 90 per cent early in the morning, was called "wet fog" but when the humidity came down to 75 per cent, it was called "dry fog".

"The dry fog layer contains mainly polluting elements such as dust and vehicle smoke which cannot be diffused but accumulate in air close above the surface of the earth. This layer has become thicker and thicker since the wind was not strong enough to blow it away," Dzung said.

The expert predicted that this situation would continue for the next several days as the southwestern wind was still very weak.

He said that as the fog layer contained some polluted elements, it could impact human health in general, and cause respiratory problems in particular.

According to the HCM City's Environmental Protection Department, air pollution in the city has reached a complicated level with 80 per cent of samples collected by the department not meeting safety standards, with a high risk of health hazards. — VNS
