The study investigates the effects of pulp mill effluent on male zebrafish, specifically looking at changes in liver and testicular structure and function.
Exposure to 4% effluent for 14 days led to changes in testicular morphology, including an increase in cysts with damage and a decrease in healthy cysts containing spermatids.
The research reveals detrimental biochemical changes in the testes, such as reduced lactate levels and increased reactive oxygen species, along with adverse effects on liver cells, including necrosis and fat infiltration.
