Adverse reproductive performance in zebrafish with increased bioconcentration of microcystin-LR in the presence of titanium dioxide nanoparticles
10.1039/C8EN00174J 2018-04-11 Abstract The aim of the present study was to investigate the reproductive effects of microcystin-LR (MCLR) in the presence of titanium dioxide nanoparticles (n-TiO2). Five-month-old zebrafish were exposed to MCLR (0, 0.5, 4 and 32 μg/L) alone or combined with... |
