This study aimed to enhance our insight on the potential toxicological effects of silver
nanoparticles (AgNPs) into the aquatic environment. To investigate the chronic toxicity of
nanoparticles, freshwater micro-crustacean Daphnia lumholtzi was exposed to different
concentrations of 0.2, 0.5 µg/l AgNPs, and control, for 21 days. Toxicological endpoints at different
growing stages such as the maturation and reproduction were recorded. The reproduction rate of D.
lumholtzi exposed to both AgNPs concentrations (0.2 and 0.5 µg/l ) was significantly lower than
that of control. In turn, the maturation exposed to both AgNPs concentrations was not significantly
different from the contr...
