Aging of TiO2 Nanoparticles Transiently Increases Their Toxicity to the Pelagic Microcrustacean Daphnia magna

Fig 3

Fecundity of Daphnia.

Median difference in the reproduction of Daphnia (± 95% CI) after 21 d of exposure to (A) 2.0 and (B) 6.0 mg nTiO2/L expressed relative to the respective control containing 0.0 mg/L nTiO2. Higher numbers indicate a decreased cumulative reproduction compared to the control. NA = not assessed due to 100% mortality in the nTiO2 treatment. Values followed by different lower case letters denote a statistically significant difference.
