THE IN VITRO EFFECTS OF SILICA NANOPARTICLES ON SPERMATOZOON OF RAINBOW TROUT (ONCORHYNCHUS MYKISS)

摘要

In recent years, silicon dioxide (SiO2) nanopar- ticles (NPS) have widely used in industry, personal care products, cosmetics, construction, catalysis, dyes (pigments) and pharmaceutical applications. This use of nano-SiOz has been associated with en- vironmental toxicity concerns. Therefore, the aim of this study was to evaluate the effect of SiO2 NPs on the motility parameters of Oncorlzynclms mykiss spermatozoon- Afterwards, Sperm samples were in- cubated with different concentrations of SiO2 NPs (1, 10, 25, S0 and 100 mg/L) at 4°C for 3 h. According to the obtained results, there were statistically signif- icant (p 0.05) in VCL (_um/s), LIN () and ALH (um) values in spermato- zoon motility against SiO2 NPs exposures at differ- ent concentrations. As a result, especially 100 mg/L concentration of SiO2 NPs has negative effects on rainbow trout ('0nc0rl2ynclms mykiss) speimatozoon in terms of sperm motility.
