Pioneer of pollution research nurtures talents

Although he has been retired for more than two decades, 88-year-old academician Wang Wenxing has not stopped nurturing talent in environmental protection and promoting research of air pollution sources.

His study of sulfur dioxide emissions and suggestions on controlling acid rain have played an important part in the reduction of air pollution nationwide, said Wang's colleague Chai Fahe, deputy director of the Chinese Research Academy of Environmental Sciences.

The concentration of major air pollutants like PM2.5 and nitrogen dioxide has been much higher than the national standards in many cities, resulting in numerous smoggy days.
