The Effect of Zinc on the Abundance of Technological Species of Earthworm <i>Eisenia Fetida</i> and Phytotoxicity of Soil
The article reveals the essence and results of two scientific experiments. The first experiment was aimed at studying the use of technological earthworms species for bioassay and bioremediation of soils contaminated with zinc acetate. The second experiment allowed us to assess the phytotoxicity of soil after exposure to the heavy metal and worms and identify out the safe and toxic levels effects of zinc on plants in the conditions of this experiment.
