No toxic levels of cyanide have been detected in water samples taken from a Tianjin river where a large number of dead fish were spotted after last week's explosions.
The analysis was conducted at around 5:30 p.m. Thursday at a section of the Haihe River, which is several kilometers away from the site of the explosions at the north China port, according to the city's environment monitoring center.
The center said that an investigation would be launched but assured that is was not uncommon for fish to die en masse in local rivers during summer, due to poor water quality.
