Air pollution is becoming severe in Hanoi, because of factories, constructions and particularly a large number of cars and motorcycles. We all have to wear masks participating in the traffic. A Hanoi artist brings this situation to his paintings, which are on display in Hanoi. An exhibition, titled “The Mask” featuring concern environment is taking place in Hanoi. 28 oil paintings express the artist’s anxiety about the air pollution and its impact on the human body. The art works are made by Nguyen Thanh, a Hanoian self-taught artist. Subjects wear masks to filter out pollution, or else show skin chapped like a field in a drought. Some are flaccid and fatigued, showing the human toll of pollution.
