PM2.5 in the Yangtze River Delta Region by Yan Lu

Winter 2013, China suffered large-scale invasion of haze, which is extremely harmful to human health. The project investigated the cause of haze in the Yangtze River Delta region. The visualization shows pollution data of vehicular, industrial and municipal emissions. According to atmospheric sampling and laboratory analysis of the haze, the causes of haze are coal, oil, and others. The project also compares the distribution of heavy pollution enterprises with NASA weather model, and therefore indicates that the flow of pollutants is brought to the Yangtze River Delta region from northern areas.
