First Rainfall Since Tianjin Explosion Leaves City Covered In Mysterious White Foam
The first rainfall to wash over Tianjin since a series of blasts struck a warehouse in the Binhai district last weekhas sparked a new wave of concern as an unidentified white foam has appeared on the streets.
Some who made contact with it are reporting a burning sensation on their face and lips, while others are reporting a stinging sensation on their arms. Some have said they experienced an itchy sensation, according to a NetEase News report.
Officials today said that at least 40 types of dangerous chemicals were detected at the blast zone, including 800 tons of ammonium nitrate and 500 tons of potassium nitrate, the Guardian reports.
Hydrogen cyanide gas is described by the US Centers for Disease Control and Prevention as being a “rapidly fatal” toxic chemical that can reduce the body's ability to use oxygen.
In preparation for the rain, authorities reportedly built cofferdams around a 100,000-square-meter core area of the explosions which will be continually reinforced to prevent contaminated water from flowing out, Xinhua said.
Local monitoring centers reported a normal air quality reading in the city, and the Tianjin deputy mayor in charge of work safety said at a press conference yesterday that sodium cyanide within a three-kilometer radius of the core blast site would be neutralized by yesterday evening.
