Xinhua News Agency ran a story reporting on a chemical spill into the Mangniu river, a tributary to the Songhua river. (Xinhua 8/23) The spill apparently occurred on Monday (8/21), and officials believe that it was due to an illegal discharge by the Changbaishan Jingxi Chemical Co. The tributary passes through the city of Jilin, which was the site of last November's big benzene spill. The major pollution component of the 5 kilometer long pollution slick seems to be Xylidine.
Unlike the benzene spill into the Songhua last year, official response to this spill appeared to be much better. Three dams were built, including 2 containing active charcoal to filter the chemicals. So far, none of the pollutants have been detected in the Songhua river.
