4. Regular Monitoring Conducting regular monitoring of the air quality in welding environments can help identify hazardous levels of particulates and ensure compliance with occupational safety standards. This monitoring should include assessments for specific contaminants present in weld smoke.

The integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO₂NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO₂NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO₂NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.

Titanium dioxide is an insoluble mineral, meaning it cannot dissolve in water. Known for its bright, white pigment, manufacturers use titanium dioxide in many different capacities, including in cosmetics, foods, and drugs. 

EFSA has updated its safety assessment of the food additive titanium dioxide (E 171), following a request by the European Commission in March 2020.

Nanotoxicology “focuses on determining the adverse effects of nanomaterials on human health and the environment.”

In the experiment, the growth of iron yellow particles can be inhibited by adding additives, so as to prepare iron oxide yellow cryst

The most significant uncertainty identified by the EU experts was the concern that TiO₂ particles may have genotoxic effects. Genotoxicity refers to the ability of a chemical to directly damage genetic material within a cell (DNA), which may lead to cancer in certain situations. Although the experts did not conclude that TiO₂ particles in E171 are genotoxic, they could not rule out the concern that they might be.
