Can you image a white Taj Mahal? In November 2017, NASA and the University of Maryland jointly published a research report stating that India’s sulfur dioxide emissions, one of the air pollutants, have risen significantly in the past 10 years, rising by as much as 50%, NASA believes India has become the world's number one emitter of sulfur dioxide emissions. Sulfur dioxide emissions come from the burning of sulphur-containing coal. In India, the presence of coal-fired power plants, residential use and coal-fired plants, sulfur dioxide emissions remain high, especially in the Indian capital of New Delhi, due to the presence of nearby factories and power plants. In the winter of 2017-2018, there was an extremely serious haze problem, the PM2.5 concentration exceeded 1000 micrograms, and the visibility was even less than 100 meters. The impact of air pollution on buildings is significant. In particular, substances such as sulfur dioxide and nitrogen oxides are converted into sulfuric acid, nitric acid and other substances through a series of chemical reactions after entering the atmosphere, forming acid rain and corroding buildings. It is also one of the important reasons why the Taj Mahal does not clean white crystal. Follow Us and make Taj Mahal be white agian!
