On April 5, 2011, a meeting was held with Ulrika Backman of VTT in their Otaniemi office. Though there were lots of restrictions to provide informations regarding VTT's ongoing researches on nanomaterials, Ulrika gave us a general idea on their activities towards nanomaterial safety issues on human health.
According to the meeting discussion, VTT is currently working on air borne nanomaterials and how much they effect on human health. In VTT laboratories, the researchers are working on the exposure level of air borne nanoparticles and based on the measurement data they are examining the toxicity level of human cells.
The researchers are also evaluating the environmental safety of nanomaterials based on five different methods.
Moreover, VTT is working on the life cycles of 4 different nanoparticles- nanocellulose, coated glass substrates, carbon nanotube composites and titanium dioxide in paint which are the mostly used nanomaterials in different consumer and industrial products.
As Ulrika said, there is nothing to get anxious regarding nanomaterials related hazards since no reported public health impacts is found yet caused by these materials. Again, in Finland, the number of air borne nanoparticles produced in the worst case scenario is very low (3000-5000 particles per cubic centimeters) compared to the other countries, e.g. Germany (20000-30000 particles per cubic centimeters).
