Toxicological and hygienic securing of safe liquidation and conversion of facilities designed to store and destroy chemical weapons
Toxic effect of different zinc compounds were investigated into biological characteristics of representatives of plankton crustaceous Ceriodaphnia affi nis Lillijesborg. Based on indicators of 48 hour and 7 day LC50, suspensions of zinc oxide micro- and nanoparticles showed a higher toxicity to Ceriodaphnia as compared to ZnSO4 solutions. The indicator of the average lifespan of animals in ZnSO4 solutions had a dose-dependent character and statistically meaningly decreased when concentration of the substance increased. An authentic decrease of a total fertility of small crustaceans over their lifespan was registered for all tested substances and concentrations except for zinc oxide nanoparticles at a concentration of 0.001 mg/l.
