Moreover, the fitted sheet's versatility extends beyond the bedroom. In hospitals, they are invaluable for their ease of use and hygiene benefits. They are also employed in hotels where a crisp, well-fitted sheet is a hallmark of quality and care They are also employed in hotels where a crisp, well-fitted sheet is a hallmark of quality and care
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.
How Is Titanium Dioxide Made?


Because of health risks, France banned titanium dioxide as a food additive in 2020. Two years later the European Union also banned titanium dioxide as a food additive.
Some people have concerns about the safety of titanium dioxide because of reports linking it to cancer.
Both calcium carbonate and titanium dioxide play crucial roles in various industries, but they are used for different purposes. Calcium carbonate is primarily used as a filler and pigment, while titanium dioxide is used as a whitening agent and pigment. Additionally, titanium dioxide is more expensive to produce than calcium carbonate due to its synthetic nature and complex manufacturing process.
Titanium dioxide, also called titania, is an odorless white powder and naturally occurring mineral that is widely used as a pigment for its brightness and whitening effects on a variety of materials, such as paint, plastic, paper, cosmetics, sunscreens, toothpastes and foods.
A 2016 review by the European Food Safety Authority concluded that titanium dioxide absorption is extremely low and any absorbed particles are mostly excreted through feces (17Trusted Source).

This food chemical has been used in food for more than half a century, but recent studies show it may be harmful.
