From stable isotope ecology to forensic isotope ecology — Isotopes’ tales [PDF]
Forensic Science International, 2019 Stable isotope ecology and forensic isotope ecology are not only linked by name. More often than not, knowledge and insights gained through the former serve as a springboard for application focused work of the latter. This review aims to offer a glimpse into the fascinating world of both though with more emphasis on forensic isotope ecology.

Study on behaviors of PO43- in the sediment of the West Lake using isotope trace technique
浙江大学学报. 农业与生命科学版, 2002 Under laboratory condition, the technique of the isotope trace was applied to investigate 32P-PO43- behaviors in water/sediments of the West Lake. The results showed that 32P-PO43- in water/sediments declined exponentialy with time.
