Mechanism of the preventive effects (How it works):
In the presence of ultraviolet light, molecules of microorganisms are entrapped and exposed to the action of the energy of free electron holes with electron energy of 3.2 eV. This energy is greater than the energy of most bonds between atoms in molecules of organic substances. Consequently, these bonds are broken and their place binds atmospheric oxygen. As can be seen from and experiment a factory smoking area (Figure 2), where the ceiling plate was illuminated by fluorescent UVA, all the smoke and deposits on the active layer decomposed.

This is a response about misleading information regarding the use of Titanium Dioxide, by persons who have not performed correct scientific standard procedures and have stated opinions that could cause serious financial harm to the European Union. Their purpose was unknown, but it is now rectified. Insufficient professional level of authors in the field of photocatalysis, material chemistry clearly lacking practical experience led to professionally incompetent, ideological text characterized by alarming text before purporting actually nonexistent danger of health risks for humans titanium dioxide. “The Scientific Council is convinced that employees of state bodies should not spread their subjective opinions without previous wide professional discussion of which would create a qualified consensus “.
With a detailed approach, the authors wrote this article detailing the professional misconduct of its authors (found in the full text of the attached document).
