[Cytotoxic influence of chlorophenols on the root meristem cells of onion batuna seeds (Allium fistulosum L.)].

Chlorophenols are precursors to more dangerous toxicants dioxanes and are characterized wiht mutagenic and carcinogenic properties. Mutagenicity and cytotoxicity of chemical substances can be studied using methods of plant biological testing under the influence of different pollutants. Genotoxic and cytotoxic effects of pentachlorophenol and 3-chlorophenol solutions in root meristem cells of Allium fistulosum (L.

[Influence of copper ions on hematological and cytogenetic parameters of fresh-water fishes Carassius auratus gibelio].

Influence of copper ions on white blood cells parameters in Carassius auratus gibelio was investigated. Changes in cytogenetic parameters and instability in erythrocytes and epithelial cells of gills were estimated in reply to influence of copper solutions. The frequency of epithelial gill cells at a stage of apoptosis was investigated.
