  Continuing on the recent observation that sudden death of entanglement can
occur even when a single qubit of a two qubit state is exposed to noisy
environment, we examine the local effects of several noises on bipartite
qubit-qutrit and qutrit-qutrit systems. In order to rule out any initial
interactions with environment, we consider maximally entangled pure states of
qubit-qutrit and qutrit-qutrit systems for our analysis. We show that
depolarizing and generalized amplitude damping noise can cause sudden death of
entanglement in these states even when they act only on one part of the system.
We also show that sudden death of entanglement occurs much faster under the
action of depolarizing noise when compared to that due to generalized amplitude
damping. This result strengthens the observation that depolarizing noise is
more effective than other noise models in causing sudden death of entanglement.
