Abstract
The biological activity of water extracts of flue dust from lead and zinc works was assayed by means of biological tests. As test species served: Pinui silvestris, P. nigra, Trifalium pratense, Cucurnis sativus variety Delikates, Raphanus sativus, Pisum arvense and Allium cepa. The extracts tested with a containing as low as 26.0 mg/ml Zn and 1.02 mg/ml Pb, caused a shortening of the roots of the tested plants. Most sensitive proved to be Cucumis sativus, Trifolium pratense and Pinus silvestris. Cytoloigical analysis of the growth apex of Allium cepa roots demonstrated that the Solutions used caused disturbances in cell division in the form of c-mitosis and lowered the value of the mitotic index.Keywords
