Major cation Mg
was present in enamel as major substituted species. The quantity of Mg and the Mg isotopic ratio in
tooth can provide information on the environment, dietary habits, and oral health of individuals. A fast and effective
method for separation, preconcentration and isotopic determination of Mg with rich calcium of tooth samples is by MC-
ICP - MS technique, after cation resin was established. Separation of Mg was achieved by cation exchange chromatography
of AG50W-X8. The ?sample - standard? bracketing technique was used to correct the instrumental mass bias. The established
method of Mg isotope provides an important scientific basis for ancient population migration, Palaeodietary analysis and
disease by Mg isotope of ancient human teeth.
He Mao-yong is mainly engaged in trace elements (B, Sr, Pb, Se, Zn, Fe, Mn, Cr, Mg, etc.) and non-traditional stable isotopes (B, Cl, Ca, Mg, Li and Fe)
determination method and to apply these trace elements and isotopes in health, environment and climate change. More than 50 relevant papers were published,
including 17 articles of SCI. His research interests include New Analytical Techniques for Isotopic Analyses using TIMS and MC-ICP-MS Paleoceanography and
Paleoclimatology and Biogeochemical Behaviors of Trace Elements and Isotopes in the Teeth.
