<p>For this study, a number of 240 adult healthy female zebrafish were divided into 12 tanks (20 fish per tank) and exposed to 0 (control, T0), 0.1 (T1), 1 (T2), and 10 (T3) mg/L synthesized polystyrene nanoplastics (PS-NPs, Nanoplastic synthesized in the chemistry laboratory of Faculty of Basic Sciences at Zabul University) for 4 weeks.
