At least 123 people were killed after a massive explosion ripped through a chemical storage facility in Tianjin port earlier this month. Now residents want to know what went wrong.
Qu Ruijing, a senior chemical researcher, and some selected Internet users took part in a Q&A session with Xinhua.
More than 40 kinds of hazardous chemicals have been confirmed as being present near the blast site in Tianjin, including sodium cyanide.
The hazardous chemicals include 700-ton sodium cyanide, 800-ton ammonium nitrate and 500-ton potassium nitrate, according to an official.
Residents raised questions on Friday about the distance between a hazardous chemical warehouse that exploded at a port in Tianjin and nearby residential neighborhoods.
At least 44 have been rescued from the debris in Tianjin Binhai New Area, after blasts originating from a dangerous-chemicals warehouse killed 56.
How did the warehouse pass safety and environmental impact assessment and were the firefighters informed of hazardous materials to before putting out fire?
Investigators searched for clues on Friday to identify what caused two huge explosions at a warehouse storing volatile chemicals at a busy port in China.
The dangerous chemicals stored in the warehouses that exploded on Wednesday night in Tianjin Port have not been identified even after more than 30 hours after the incident due to several reasons.
The dangerous chemicals stored in the warehouses that exploded on Wednesday night in Tianjin Port can not be determined at the moment, authorities said at a press conference on Friday.
An explosion ripped through a warehouse at the Binhai New Area in Tianjin at 11:34 pm on Wednesday. The warehouse stores dangerous chemical goods.
