Scholarcy highlights

  • Boron contamination of aquatic ecosystem has received considerable critical attention due to its toxic effects at high concentrations on plants as well as animals
  • Blood cells were more vulnerable than sperm cells to B exposure
  • Previous studies on toxic effects of B have not dealt with DNA damages in blood and sperm cells of Nile tilapia, together with blood parameters
  • This study consisted of two successive experiments purposes to determine these findings, including the median-lethal concentration of B for Nile tilapia
  • Nile tilapia were treated with five elevated B concentrations and hematological, serum biochemical parameters, and DNA damages of Nile tilapia in these treatments were determined comparing with the control after 14 days of exposure
  • Hematological parameters were similar to each other in all groups while serum biochemical parameters in B treatments, especially in 50 and 100 mg L−1 B groups, were found significantly higher. These results demonstrated the harmful effects of B at high concentration on the DNA integrity of blood and sperm cells, and the serum biochemical parameters
