In addition, it has been already observed that the isotopic compositions of elements in different biological samples exhibited an increasing trend [17] , [27] – [28] , such as the δ 30 Si values for different organs of rice (stem < root < leaf < husk <grain) and the δ 13 C values for different tissues of gerbil (fat < liver < muscle < brain < hair).
