Aging of nanosized titanium dioxide modulates the effects of dietary copper exposure on Daphnia magna - an assessment over two generations.

Nanosized titanium dioxide (nTiO) is widely used in products, warranting its discharge from various sources into surface water bodies. However, nTiO co-occurs in surface waters with other contaminants, such as metals. Studies with nTiO and metals have indicated that the presence of natural organic matter (NOM) can mitigate their toxicity to aquatic organisms.
