We've used titanium dioxide safely for decades. However, recently its safety was called into question. 
 
At CRIS, we've explored the safety of titanium dioxide for nearly half a decade, including conducting double-blind research to test the safety of food-grade titanium dioxide (E171). Our study shows that when exposed to food-grade titanium dioxide in normal conditions, research animals did not experience adverse health outcomes.
 
It's important to emphasize that in a National Institutes of Health study, experimental animals were exposed to titanium dioxide in amounts as high as 5% of their diet for a lifetime and showed no evidence of adverse effects. 
 
A handful of studies greatly influenced the decisions made by the European Food Safety Authority (EFSA). Unfortunately, these studies did not consider that titanium dioxide exposure comes from food, not drinking water. Additionally, CRIS researchers could not reproduce the adverse outcomes identified by the studies through typical food ingestion. Regardless, the EFSA banned E171 as a food ingredient and for use in other capacities in the summer of 2022.
 
In 2022, the United States, United Kingdom, and Canada maintained that the scientific evidence supports that titanium dioxide (E171) is safe for humans to use and consume.

  • The Importance of Manhole Cover Companies in Urban Infrastructure


  • Another essential aspect of heavy-duty parking posts is their role in promoting safety. In busy parking lots, the interaction between vehicles and pedestrians can lead to accidents. By strategically positioning parking posts, property owners can create clear pathways for pedestrians, minimizing the likelihood of unexpected encounters with moving vehicles. Furthermore, these posts can act as barriers that protect pedestrians from errant vehicles, ensuring that individuals remain safe while walking through parking areas.

  • The significance of manhole covers can also be understood through their historical context. In cities like Paris and New York, manhole covers have evolved alongside urban development. In Paris, the iconic Société Parisienne de Distribution d'Eau covers are renowned for their distinctive designs, rich with history that dates back to the 19th century. Similarly, New York’s heavy cast-iron covers, often adorned with the initials of utility companies, have become symbolic of the city’s industrial past. These covers act as historical markers, providing insight into the socio-economic factors that shaped urban environments.

  • Building Community Connections


  • Gate valves operate with a simple mechanism they consist of a gate or wedge that moves up and down to open or close the flow path. When the gate is lifted, fluid flows freely; when it is lowered, the flow is completely obstructed. This design allows gate valves to provide minimal pressure drop when fully open, making them suitable for applications where uninterrupted fluid flow is essential.

  • Beyond individual protection, driveway lockable posts contribute to a larger sense of community safety. By discouraging crime in one area, the presence of these posts can have a ripple effect, encouraging other homeowners to adopt similar security measures. This collective proactive approach fosters a safer neighborhood, enhancing residential security and community trust.


  • Litter bins serve several purposes, each contributing to the overall well-being of the urban environment. Firstly, they provide a designated space for waste disposal, which helps to prevent littering. When people have easy access to bins, they are more likely to dispose of their trash responsibly rather than tossing it onto the streets or sidewalks. This simple act of using a litter bin can significantly reduce the amount of waste that ends up in our parks, roads, and waterways, thereby protecting wildlife and maintaining the beauty of our surroundings.

  • Furthermore, the implementation of lockable bike racks aligns with many cities' broader sustainability initiatives. By encouraging the use of bicycles, cities can work towards their goals of reducing carbon footprints and improving air quality. Many urban centers are investing in cycling infrastructure as part of their climate action plans, recognizing the role of active transportation in combating climate change. Lockable bike racks serve as a vital component in this infrastructure, facilitating the transition to greener modes of mobility.
