Shear studs are typically welded to the steel section of a composite beam before concrete is poured. Their primary function is to transmit shear forces between the steel and the concrete, preventing the two components from sliding apart under load. This connection enhances the load-carrying capacity of the beam and allows for a more efficient use of materials, ultimately leading to lighter and more cost-effective structures.

But despite all these cries of alarm, five years on from the original study no further testing into the safety of Titanium Dioxide in our food supply
Following the filtration, the precipitate is washed thoroughly to remove any impurities and excess reagents. This is a crucial step, as thorough washing ensures that no contaminants interfere with the final mass measurement. Once washed, the precipitate is dried in an oven at a controlled temperature to remove moisture, ensuring that the mass recorded reflects only the titanium content.
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.

What Is Titanium Dioxide?
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.
It’s produced through the sulfate or chloride process, which both involve treating titanium ore with sulfuric or hydrochloric acid to produce titanium sulfate or titanium chloride. These materials are then further processed to remove impurities and produce titanium dioxide in its final form.
Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
Although food-grade titanium dioxide must be 99 percent pure, there’s still a risk of it containing potential contaminants, such as mercury, lead and arsenic. Additionally, inhaling the mineral over time can possibly cause it to build up in your body, leading to adverse effects.
