Greenpeace Expresses Concern Over Tianjin Blast
Greenpeace has expressed grave concern over the chemicals part of the recent explosion in Tianjin. The Tianjin Tanggu Environmental Monitoring Station has said that sodium cyanide (NaCN), toluene diisocyanate (TDI) and calcium carbide (CaC2) all pose serious health risks to anyone who may come into contact with them.
Moreover, a possible explosion can occur should TDI and CaC2 react with water and other reactive chemicals. This proves to be a dangerous possibility especially when the upcoming forecast calls for rain. In addition, Greenpeace has also warned that rain can spread airborne pollutants into water systems, affecting both local ecosystems and ground water supplies.
A series of explosions rocked Tianjin in northern China on Wednesday, killing as much as 50 people, BBC has learned. Among the casualties were 12 firefighters with 36 of their colleagues still reported missing. Meanwhile, more than 700 people have been reported injured.

The first explosion happened at about 23:30 local time (15:30 GMT) in an industrial zone known as the Binhai New Area. It was then followed by a second more powerful blast and then, a series of smaller ones. Buildings that were standing within a 2km radius of the blast site had their windows blown out. Office blocks were also destroyed.
The explosion was so huge that it was even captured by the Japanese weather satellite, according to Vox. The blasts actually occurred in a warehouse that was storing a number of toxic chemicals including NaCN and TDI along with other flammable substances and compressed natural gas.
The company who owns the warehouse readily stores dangerous chemicals
The warehouse where the blasts occurred belongs to Tianjin Dongjiang Port Rui Hai International Logistics Co. Ltd. It has been using Tianjin Port as a storage and distribution center of containers filled with dangerous chemicals. The company’s freight volume is around one million tonnes a year. Its annual revenues have reportedly gone over 30 million yuan.
