For years scientists have raised concerns about the potential toxicity of titanium dioxide.
This food chemical has been used in food for more than half a century, but recent studies show it may be harmful.
Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”
On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”
In its statement to USA TODAY, the FDA maintained that, in all post-approvals for food additives, our scientists continue to review relevant new information to determine whether there are safety questions and whether the use of such substance is no longer safe under the Federal Food, Drug, and Cosmetic Act.

Truck brake systems operate under high-stress conditions, generating significant heat during operation. However, when temperatures plummet, the brake drums can become cold and, in extreme cases, ice over, leading to reduced effectiveness and, consequently, increased stopping distances. The wood heater serves as a preventative measure against these cold-weather complications. By providing a steady source of heat, it helps maintain the optimal temperature of the brake drums, ensuring that the brakes remain responsive.

Z drugiej strony, hamulce tarczowe oferują lepszą wydajność hamowania. Działają poprzez zaciskanie klocków hamulcowych na obracającą się tarczę, co pozwala na szybsze i bardziej skuteczne zatrzymywanie pojazdu. Hamulce tarczowe są mniej podatne na przegrzewanie się (tzw. fading), co jest istotne podczas intensywnego użytkowania, na przykład w przypadku jazdy sportowej lub w trudnych warunkach terenowych. Dzięki lepszemu odprowadzaniu ciepła, hamulce tarczowe zapewniają bardziej stabilne osiągi hamowania, co czyni je popularnym wyborem w nowoczesnych samochodach.
How to Change Rear Drum Brakes A Step-by-Step Guide
Using a brake adjusting tool or a flathead screwdriver, turn the adjusting mechanism. For increasing brake contact (adjusting up), turn the wheel or lever until the shoes make contact with the drum. You want just enough tension for a slight drag when rotating the drum by hand. To decrease contact (adjusting down), turn in the opposite direction until the shoes clear.
