Case Study Paints and Lacquers with Silica Nanoparticles - Safety of Nanomaterials along Their Lifecycle - page 394

complement the previous studies with studies on emissions/exposures observed dur-
ing use of engineered and local exhaust ventilation control and to conduct toxicologi-
cal study on these dust materials as well. This will be increasingly important when
adding more complex MN, such as the doped biocidal silica reported in Table 17.1,
to the products. Potentially, the effects on mass-dose basis of finer size particles
would be different from that of the total generated dust due to the inhibitory effect
of the matrix reported so far. In addition, products containing MN doped with toxic
compounds should be tested in greater detail for longer exposure times to ensure that
sudden breakdown of the matrix will not cause a delayed hazardous impact.
