The effect of zinc oxide nano- and microparticles and zinc ions on freshwater organisms of different trophic levels

Data on the effects of various forms of zinc compounds on the biological parameters of freshwater animals (Ceriodaphnia affinis Lillijeborg, 1862; Chironomus riparius Meigen, 1804; and Brachydanio rerio Hamilton-Buchanan, 1822) are presented. Crustacean Ceriodaphnia affinis is the most sensitive test object studied.
