Clean and fresh air in a scenic area is a basic requirement of every tourist. The factors affecting the air quality of a scenic area that must be evaluated include: (1) gaseous pollutants, including sulphur dioxide, nitrogen oxides, hydrocarbons, carbon oxides, fluorides and ozone; (2) solid particles, including soot and dust, greater than 10 μm and fly dust less than 10 μm; and (3) aerosols, which are particles smaller than 1 μm suspended in the air that are composed mainly of inorganic compounds and a variety of organic compounds, organic polymers and volatile organic compounds. The air quality of a scenic area must reach the Class 1 atmospheric standard, and the minimum acceptable standard is Class 2.
