Concentration of lead that analyzed on June in P. merguiensis was lowest (0.065 mg/kg) and the highest was in M. ensis (0.073 mg/kg). There was no differences of lead concentration in various species were collected on common month. The differences of lead concentration were significant found in common species were collected on various month.
