Relationship between Air Pollutants and Visibility in Shanghai during 2006-2010

Abstract:

Air pollution has been deteriorated seriously in Shanghai as a result of urbanization and modernization. Visibility reduction is the most apparent symptom of air pollution. This paper aims to describe the characteristics of visibility and air pollutants in Shanghai, and to investigate the relationship between them. Visibility in Shanghai was higher in summer and lower in winter. The mean value of visibility during 2006-2010 was 17.8km. Air pollution in Shanghai was also serious. In 2010, Shanghai got the relative better air quality compared with the former four years. Air pollutants and visibility were negatively correlated. SO₂ and NO₂ had higher correlation coefficients with visibility than PM₁₀. This suggested that the visibility in Shanghai was mainly due to secondary pollutants.
