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.
研究了工业废料——褐煤燃烧后的灰烬的毒性以及将其用于农业的可能性。已证明，pH值较低的灰水提取物对测试对象实际上无毒。富含氧化钙和氧化镁的灰提取物pH值较高，对水生生物有负面影响。中和作用可消除急性毒性作用。
