The 2005 Jilin chemical plant explosions are a significant chapter in the environmental history of Chinese industrialisation. An explosion at the China National Petroleum Corporation facility in the Longtan district killed five workers and sent a massive benzene contamination slick down the Songhua River — a river that serves as the drinking water source for millions of people downstream, including the city of Harbin.
The incident is not commemorated formally, but the plant area in Longtan district is a landmark in the context of China's environmental awakening and the gradual development of environmental regulation and enforcement. For visitors interested in industrial history and environmental policy, the Longtan industrial district — the heavy industrial zone north of the city centre — represents the scale of northeast China's Soviet-influenced industrial development and some of the costs that came with it.
