Titanium dioxide / Titandioxid Nanno Nano

Titanium dioxide has recently been classified by the International Agency for Research on Cancer (IARC) as an IARC Group 2B carcinogen ”possibly carcinogen to humans”. Titanium dioxide accounts for 70% of the total production volume of pigments worldwide. It is widely used to provide whiteness and opacity to products such as paints, plastics, papers, inks, foods, and toothpastes. It is also used in cosmetic and skin care products, and it is present in almost every sunblock, where it helps protect the skin from ultraviolet light.
With such widespread use of titanium dioxide, it is important to understand that the IARC conclusions are based on very specific evidence. This evidence showed that high concentrations of pigment-grade (powdered) and ultrafine titanium dioxide dust caused respiratory tract cancer in rats exposed by inhalation and intratracheal instillation*. The series of biological events or steps that produce the rat lung cancers (e.g. particle deposition, impaired lung clearance, cell injury, fibrosis, mutations and ultimately cancer) have also been seen in people working in dusty environments. Therefore, the observations of cancer in animals were considered, by IARC, as relevant to people doing jobs with exposures to titanium dioxide dust. For example, titanium dioxide production workers may be exposed to high dust concentrations during packing, milling, site cleaning and maintenance, if there are insufficient dust control measures in place. However, it should be noted that the human studies conducted so far do not suggest an association between occupational exposure to titanium dioxide and an increased risk for cancer.
Skall vi vänta tills 2013 eller skall vi hjälpa tillverkarna på vägen? Köp inte produkterna så kommer det att gå så mycket fortare!
Om en människa utvecklar en autoimmun sjukdom så har det redan gått lite för långt. När immunförsvaret vänder sig mot den egna kroppen och attackerar den… ja då står solen högt upp och de vita tänderna gör ingen större skillnad. Pengarna på bankboken och Hummern i garaget går inte att ta med sig till den andra sidan……

The manufacture of TiO2 nanoparticles is a huge industry, Schiestl said, with production at about two million tons per year. In addition to paint, cosmetics, sunscreen and vitamins, the nanoparticles can be found in toothpaste, food colorants, nutritional supplements and hundreds of other personal care products.
”It could be that a certain portion of spontaneous cancers are due to this exposure,” Schiestl said. ”And some people could be more sensitive to nanoparticles exposure than others. ”I believe the toxicity of these nanoparticles has not been studied enough.”
