We also consider the accretion of radiation, matter and vacuum energy during respective dominance period. In this scenario, we found that radiation accretion efficiency should be less than 0.366 and accretion rate is much larger than previous analysis by B. Nayak et al. \\cite{ns}. Thus here primordial black holes live longer than previous works \\cite{ns}. Again matter accretion slightly increases the mass and lifetime of primordial black holes.
