Zero-field muon spin relaxation (μSR) measurements were applied to the Zn-substituted Bi-2212 system, Bi2Sr2Ca1-xYx(Cu 1-yZny)8+δ, to study a possibility of the existence of the so-called "1/8 anomaly" which was established in the La-systems. The muon spin depolarization rate of a Zn-substituted (y = 0.025) system at a hole density of about 1/8 per Cu-atom (x = 0.3125) increased with decreasing temperature below 5 K. The depolarization behavior at low temperatures was well described by an exponential-type relaxation function. The possibility of the existence of the "1/8 anomaly" in the Bi-system is discussed.
