The nano particles are very dangerous everywhere, even in toothpaste, antiperspirants, briefs, cosmetics , fume incinerators (Tridel etc ...) ... too many micro-particles everywhere ... Worse than asbestos ...
When research on nano particles were embryonic, many researchers already knew that they could be very dangerous especially when they were in the form of aerosols or air. Most imagined that such "dust" in the lungs would be devastating. But in the name of money and profit, taking advantage of the laziness of people are found everywhere. In your pants like that you also do not have to wash them often. ...
Nanoparticles of titanium dioxide produced in the lung inflammatory effects similar to asbestos, a study by Swiss and French researchers. Scientists are sounding alarm on nanoparticles of titanium dioxide because it is one of the most nanomaterials répandus.Plus two million tons of nanoscale titanium dioxide (nano-TiO2) are produced each year worldwide. Used as a pigment and opacifier, the nanomaterial in the composition of paints, cosmetics, creams, medicines, toothpaste, food coloring and many other everyday products.
Previous studies have shown that nano-TiO2 can cause inflammation, but the mechanisms remain unclear, write Researchers from the Department of Biochemistry at the University of Lausanne (UNIL) and the University of Orleans (F) and French National Centre for Scientific Research (CNRS) in the U.S. journal 'PNAS'. But according
their work, the TiO2 nanoparticles produce effects similar to those of two other well-known environmental irritants, asbestos and silica. Like them, they activate the inflammasome NLRP3 - a multi-protein complex causing an inflammatory reaction - and the production of reactive oxygen toxic molecules that can attack DNA, proteins and cell membranes. Even
power
The study's lead author, Professor Jürg Tschopp of the University of Lausanne, Prix Louis-Jeantet Prize for Medicine in 2008, is known for his discovery of the early inflammasomes 2000s. He said the results clearly show a pro-inflammatory activity of nano-TiO2 in the lung and the peritoneum.
The researchers worked with human cells and in vitro and in vivo in mice. The nano-TiO2 deploys a "great activity, "said the ATS Prof. Tschopp, similar to that of uric acid and asbestos, respectively responsible for gout and asbestosis.
"Asbestos and the nano-TiO2 are very similar and have the same power," said Jürg Tschopp. In their study, the researchers highlight a possible risk of cancer caused by inflammation, especially in people exposed to significant concentrations of these nanoparticles.
Precaution
"Our data suggest that nano-TiO2 should be used with greater caution than it is now, "they write. "Better care should be taken" to limit its intake in industry and in everyday life.
Prof. Tschopp said that "we now have good scientific evidence" and that now is "a political issue." "There are already committees in several countries considering action," he notes.
Similar incentives for caution had been expressed after the first evidence of association between inhalation of asbestos and lung inflammation. But "it took almost 100 years and countless deaths until the asbestos is banned," conclude the scientists, who hope that "decisions will be taken to prevent possible diseases and may be death. "
