The concentration in four categories, i.e., Cd, Pb,
Hg and Cr showed lower contents than maximum
allowable limit of RoHS (Table 4). The total bromine
contents (T-Br, as an indicator allowing to estimate, if
other brominated substances than the specifically
analyzing brominated flame retardants occur in a plastic
samples) were also analyzed. Although T-Br (22,449
ppm) exceeded the standard limit of RoHS, however, it
is undeterminable whether T-Br exceeds the permitted
concentration of RoHS or not, because brominated
flame retardants (BFRs) affiliated with
tetrabromobisphenol A (TBBPA), brom epoxy and
halogen free are mainly used for housing cover of
display product.
