title: [Comparative evaluation of the toxicity of aqueous extracts of the ashes of brown coals].
abstract: The toxicity of industrial waste--the ashes of brown coals in connection with the possibility of their utilization in agriculture has been studied. It has been proved that ash water extracts which give low pH values are practically nontoxic for test objects. Ash extracts rich in calcium and magnesium oxides provide high pH values and has a negative effect on hydrobionts. The neutralization removes the acute toxic effect.
