From studies deemed relevant, the experts found that titanium dioxide as a food additive is poorly absorbed by the gastrointestinal tract of mice and rats, with no adverse effects observed in short-term studies in rodents receiving titanium dioxide in their diets. No observed adverse effect levels (NOAELs) of 15,000 milligrams per kilogram of bodyweight (mg/kg BW) per day and 5,000 mg/kg BW per day—the highest doses tested—were established for mice and rats, respectively.
Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.
Prof. Matthew Wright, chair of EFSA’s working group on E171, noted: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”
It could also accelerate the search for new drugs and materials by simulating complex chemical reactions and molecular interactions, potentially leading to more effective treatments and innovative materials It could also accelerate the search for new drugs and materials by simulating complex chemical reactions and molecular interactions, potentially leading to more effective treatments and innovative materialsm802048.
This level of precision not only improves the performance of the final product but also reduces the risk of costly failures down the line This level of precision not only improves the performance of the final product but also reduces the risk of costly failures down the linebearing manufacturing machine.
The high load capacity and rigidity make it suitable for heavy-duty applications, while the low friction and heat generation ensure efficient energy transfer and reduced maintenance costs The high load capacity and rigidity make it suitable for heavy-duty applications, while the low friction and heat generation ensure efficient energy transfer and reduced maintenance costs22214 bearing. Additionally, the bearing's ability to accommodate misalignment reduces the risk of premature failure and extends its service life.
Rich themes: In addition to the regular exhibition, a series of seminars and activities were also held during the exhibition, covering new energy, future automobile maintenance, auto parts industry career development and many other fields. In addition, there are intelligent driving, racing, classic car display, car painting and other elements of the exhibition, to bring more rich and wonderful experience to exhibitors and visitors.
