Resumo
The influence of different concentrations of TiO2 nano-particles water suspensions (anatase and rutile isoforms) on survival and fertility of cladocerans Ceriodaphnia affinis was investigated. A statistically significant decrease of crustaceans survival in 400 mg/l and 100 mg/l anatase water suspensions over 7 days was observed. Median life span of animals authentically differed from control values in rutile 2.00 mg/l and 0.2 mg/l suspensions and anatase in all studied concentrations. The indicator value decreased with an increasing substance concentration (r=-0.21; p < 0.02). TiO2 isoforms produced negative effect on the Ceriodaphnia reproduction function. An authentic reduction of crustaceans total fertility over life span was recorded for anatase in concentrations of 0.2 mg/l and 0.02 mg/l and rutile in concentration of 0.2 mg/l. Anatase having equal concentrations with rutile posed a more expressed toxic effect on Ceriodaphnia which is linked to its lesser particles size.
