ZAGREB, Croatia - Croatia has recorded higher-than-usual levels of aluminum in the Danube following the last week's sludge spill in Hungary, but authorities say the levels are harmless to people and the environment.
The Croatian Office for Protection and Rescue said Thursday that an analysis of the water taken two days earlier where the Danube reaches Croatia showed the level of aluminum was 4.5 times higher than its usual maximum.
It says, however, that it dropped to 2.1 times higher on Wednesday afternoon, "which could indicate a fast passing of the wave of pollution."
The Croatian Toxicology Agency said the levels posed no danger to health. From Hungary, the Danube flows to Croatia. The country has been checking the water ever since the spill there.
