Abstract ：We observe the spectra of molybdenum for the first time since the first wall of our experimental advanced superconducting tokamak (EAST) was changed mainly to molybdenum tiles. A large amount of molybdenum accumulated in the central plasma where the long-lived $m=1$ mode instability bursts is shown. Molybdenum is proved to be the main impurity species observed during the formation and lifetime of impurity-induced long-lived $m=1$ mode. This may indicate that a close relationship exists between the high-$Z$ impurity accumulation and the occurrence of long-lived $m=1$ mode in EAST plasmas.
