Trophic transfer potential of two different crystalline phases of TiO 2 NPs from Chlorella sp. to Ceriodaphnia dubia.

•Dietary exposure of NPs induced mortality only at their higher concentrations.•Lower concentration of TiO2 NPs showed higher biomagnification potential.•High BMF values were obtained for individual NPs, especially at 75 μM.•Irradiation and crystallinity have an impact on Ti accumulation alone, not mortality.•Binary mixture reduced the mortality and biomagnification of individual NPs.
