No eye irritation data are available for
tungsten dioxide (target substance). However, eye irritation data are
available for tungsten trioxide (source substance), which were used for
to similar physical-chemical properties, similar or lower
transformation/dissolution results and similar or lower in vitro
bioaccessibility in synthetic body fluids for tungsten dioxide (the
target substance) than tungsten trioxide (the source substance), the
resulting toxicity potential would also be expected to be similar or
lower, so read-across is appropriate. Therefore, the dose descriptors
are expected to be sufficiently similar or higher for the target
substance, and read-across to the source chemical is adequately
protective. For more details refer to the description of the read-across
