As demonstrated so far, SPARQL queries can be used to extract information, such as the physicochemical properties of ENMs. This way we can for example plot all the reported primary size values, as shown in Figure . The shape of the point marker indicates whether an ENM causes DNA damage or not and the nanomaterial type is color coded similar to Figure (with the addition of zinc and cerium oxides colored orange and pink, respectively). The obtained data suggest that for e.g. silver nanoparticles (shown in yellow) the ENMs with a small primary size value are more likely to cause DNA damage (below 26 nm, 4/6 cause DNA damage, while 30 nm and above 0/4), while e.g., titanium dioxide nanoparticles seem to cause DNA damage regardless of their size. When looking at the fractions in the Figure caption in more detail, we see that, according to the data in our RDF, no CNTs cause DNA damage (0/15), while for titanium dioxide particles 6 out of the 7 titanium dioxide particles, for which a primary size value was reported in literature, do cause DNA damage. Similarly, a large fraction of the cerium oxides, zinc oxides and silver-containing nanomaterials cause DNA damage, while our RDF does not contain data on DNA damage for e.g. iron oxides or other metal oxides (0/13).
