TiO2 NPs appeared to be more toxic to nematode Caenorhabditis elegans than submicron-sized TiO2.  At a concentration of 1 mg/l, 7 nm particles affected its fertility and survival rate and were more toxic than 20 nm anatase particles. Similarly, Hu et al. showed that rutile particles (10–20 nm), at concentrations above 1 g/kg soil, can be bio-accumulated in earthworms, where they induce oxidative stress, inhibit the activity of cellulase and induce DNA and mitochondrial damage.

Titanium dioxide production is not without its environmental impacts. The traditional process involves mining rutile ore, which can lead to significant land disruption and potential pollution if not managed carefully. Moreover, the conversion of raw ore into usable TiO2 requires energy-intensive processes that contribute to carbon emissions. As such, consumers and manufacturers alike are increasingly seeking suppliers committed to sustainable practices.
