Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.
In order to evaluate the penetration of the nanoparticles, eight adult male Wistar rats (3 months old) were used for the in vivo experiments. The protocol was approved by the local University Committee for animal testing and is in accordance with the Canadian Council on Animal Care (CICUAL-RD-2021–892-E-UNC-DEC#FCQ).
Moreover, a 2019 study noted that food-grade titanium dioxide was larger and not nanoparticles. Hence, the authors concluded that any titanium dioxide in food is absorbed poorly, posing no risk to human health (3Trusted Source).

4. Environmental Benefits As cities pivot towards more sustainable practices, installing bike racks is a step towards reducing reliance on cars. Fewer cars on the road lead to lower greenhouse gas emissions and improved air quality, creating healthier environments for everyone.
Manholes are usually round, primarily because roundness is the best shape to resist the compression of the earth; covers are round because they are easier to manufacture than square or rectangular shapes, they are easier to move by rolling, and they can't fall into the opening.[5] But in the United Kingdom they are nearly always square, or rectangular, in shape, at least at street level. Manholes can also be found in a triangular shape (e.g. in Cambridge, and surrounding villages).[6]
Manhole covers serve multiple purposes. First and foremost, they provide crucial access to underground utility systems, such as sewers, electrical conduits, and telecommunications lines. They are designed to hold the weight of vehicles and pedestrians while preventing anyone from accidentally falling into the opening. However, when a manhole cover is missing, the situation changes drastically. The exposed hole not only endangers lives but can also disrupt traffic flow and cause property damage.
