Strong absorption lines of previously unexplored heavy elements in Sirius are analyzed in the near-UV region. Several lines of Mo II (Z = 42), Cd II (Z = 48), W II (Z = 74), and Pb II (Z = 82) are confirmed. Detailed analyses of these lines suggest that abundances of these elements are all nonsolar in Sirius.
