Titanium dioxide is recognized as class 2B carcinogen by EU, so is Ultra Air products at risk of cancer?
In fact, this is a problem that you don’t need to worry about at all.
According to the carcinogenic risk to human beings, IARC (International Cancer Research Institute), a subsidiary of the World Health Organization, classifies chemicals with carcinogenic risk to human body into four categories:
Category 1: it is carcinogenic to human beings and has definite carcinogenicity.
Category 2A: it is likely to cause cancer to human beings. There is sufficient evidence to prove that it is carcinogenic to experimental animals but limited evidence to human carcinogenicity.
Category 2B: it may cause cancer to human beings. There is no sufficient evidence to prove that it is carcinogenic to experimental animals, and there is insufficient evidence to prove carcinogenicity to human beings.
Category 3: the carcinogenicity of human beings cannot be classified, and the carcinogenicity possibility to human beings is relatively low.
Category 4: it is likely not to cause cancer to people. Among them, the so-called Category 2A includes “intake of red meat” (pork, mutton and beef), “Shift work involving circadian rhythm disorder” (Simply speaking, staying up late);
Besides “titanium dioxide”, there are also “coffee” that people drink everyday “. From this perspective, aren’t we “carcinogenic” every day “?
However, please remember a famous saying in the medical field that “talking about curative effect without dosage is like playing rascal”, which is the same in the field of toxicology, you don’t pour hundreds of cups of coffee into your stomach every day. What are you afraid.
And in fact, it is not titanium dioxide itself that is really likely to cause cancer, but because of its “thin body”.
Whether titanium dioxide or not, as long as human beings are exposed to insoluble tiny particles with high concentration (e.g. 10mg/m3) for a long time, these tiny particles may indeed cause related diseases after being absorbed into the lungs for a long time.
However, even for those who are engaged in the production of titanium dioxide, the concentration of titanium dioxide that they can contact is generally only 0.3mg/m3-6mg/m3, let alone ordinary consumers?
What’s more, when the titanium dioxide is processed, especially the nanoscale titanium dioxide adopted by the ultraviolet air, it is firmly embedded in the molecular gap of the carrier (such as the air conditioning filter), if you can’t wash it off, how can you run to human lungs through the trachea?
