The 87Sr/86Sr ratios between water and biogenic material are similar in marine and lacustrine environment. Pb isotope ratios are, however, reported not to have been corresponding between the biological tissues and ambient water in aquatic system, contrary to the Sr isotope ratios. In order to explore the potential application of two isotopes as environmental tracers, we report here the isotopic compositions of strontium and lead of gastropod shell in fresh water in Jinan area. The 87Sr/86Sr ratios of carbonate shells of gastropod living in fresh stream water, are similar as that of ambient water but are different by sites. The different 87Sr/86Sr ratios of stream water between the sites is likely caused by the difference of the isotopic composition of Sr derived form rocks in the basin. In contrast,
there is a distinct difference of the lead isotopic values between the water and the gastropod shell, suggesting that shell-fish available lead in aquatic system is different from dissolved lead in water. It is assumed that the majority of Pb in stream water is derived from atmospheric Pb accumulated on soil materials over years rather than from rock.
