Soil collembolan is deemed as an epitome of soil invertebrate and medium-sized soil animals because of its abundance in species and hugeness in biomass.
Uranium isotope abundance ratio has been measured by total sample evaporation and signal integration,and a thermal surface ionization mass sepctrometry equipped with multicollector has been used.
