Assessment of DNA Damage Induced by Velum® Prime in Human Lymphocytes

Aim: Fluopyram is a mitochondrial complex II inhibitor with low water solubility and a relatively long half-life in soil. So it may also be dangerous for humans. The effect of fluopyram on DNA damage was evaluated in human lymphocytes using the comet assay. Materials and Methods: Lymphocytes of eight volunteers were isolated using histopaque-1077. Fluopyram was administered at doses of 0.05, 0.25, and 1.00 mg/mL for 1, 2, and 4 h. The comet assay was applied, and photographs of the slides were taken under a fluorescence microscope. 50 cells per slide were analyzed using the OpenComet software. The obtained results were statistically evaluated using one-way ANOVA. Results: Fluopyram treatments at 1.00 mg/mL for 1 h and 0.05, 0.25, and 1.00 mg/mL for 2 and 4 h resulted in a statistically significant increase in DNA damage compared to the internal control groups (p
