摘要：The use of waste in land reclamation projects or road works is
a generally applied method of waste recycling since coal bottom ash can be
used in plant substrate. This paper presents the results of research on the
physical and chemical properties and the toxicity of waste originating from
power stations, in the form of coal bottom ash collected from pulverisedfuel
and fluidised-bed boilers. To evaluate the eco-toxicological properties
of waste, a series of plant growing tests were conducted, with the use of
selected plant species, as well as germination tests in water extracts of waste.
The latter were intended to determine whether coal bottom ash displayed
cytostatic activity, while, in the case of pot experiments, the purpose was to
determine the germination rates and growths of both above-ground and
underground parts of plants. The test results indicated that the influence of
the tested coal bottom ash on the plant development and growth depended
on physical and chemical properties of that waste. The reactions of plants
were also changing depending on the proportion of waste in soil.
