The dependence of pseudo-scalar masses and decay constants on the sea and valence quark masses is investigated in the pseudo-Goldstone boson sector of QCD with two light quark flavours. The sea quark masses are a.t present in the range $m, 5 mud < trn,, whereas the valence quark masses satisfy imseo
