Thirteen is the ph content of bleach
And how far has it traveled to hit the danube and it's still a ten?
It's not diluting to fast for such a high concentrate of water.
Think bleach
The ph level is still high enough to irritate the skin
Thirteen was burning it
People were doused with this stuff in the town where it broke at.
Their homes were flooded with it.
The red sludge reached the western branch of the Danube early Thursday, Hungarian rescue agency spokesman Tibor Dobson told the state MTI news agency. He did not address concerns that the caustic slurry might contain toxic metals but said its pH content had been reduced to the point where it was unlikely to cause further damage to the environment.
Dobson said the pH content, which officials earlier said was at 13, was now under 10 and no dead fish had been spotted where the slurry was entering the Danube. The National Disaster Management Directorate, in a separate statement, said the pH value was at 9.3 and constantly decreasing. Normal ph levels for surface water range from 6.5 to 8.5.South of Hungary, the Danube flows through Croatia, Serbia, Romania, Bulgaria, Ukraine and Moldova before emptying into the Black Sea.
