Abstract

Current study aims to ascertain the harmful effects of pozzolanic cement (PC) on water quality and several indicators of aquatic life. Also, the effects of PC on different life stages of rainbow trout were investigated. The PC caused an increase in various water quality parameters including pH, suspended particles, turbidity, and conductivity. In rainbow trout, no significant differences were observed between control and experimental groups in terms of enzyme parameters. Also, this study revealed that the PC has impact on various hematological parameters. The PC was linked to histological changes in gills, DNA migration was observed in the rainbow trout exposed to PC. After 24 h, LC50 values of rainbow trout exposed to PC were 499.06, 324.66, and 361.26 mg/L for egg, alevine, and fry respectively. There was adverse relation between temperature and LC50. Consequently, cement pollution in the water and different stages of rainbow trout causes various negative effects.
