Groundwaters in Cainozoic sand and gravel aquifers in the arid Ti‐Tree Basin are becoming intensively used for irrigation. Carbon isotope chemistry indicates that most of the groundwaters in this basin were recharged in the Holocene. Estimated 14C

Physico-chemical data and isotopic studies (utilising H14CO3, H2 18O, 3H2O) suggest that hypersaline meromixis in Ellis Fjord (Vestfold Hills, Antarctica) was initiated during the middle Holocene period, when hypersaline brine, excluded during the an

Environmental radiocarbon was used to study aspects of groundwater origin, transport and mixing in the aquifer system underlying northern Victoria. The clearing of native vegetation and the advent of irrigation on the northern plains have upset the h

Carbon isotope chemistry indicates episodic palaeorecharge of groundwater in the arid Amadeus Basin, central Australia. In this hydrogeologically complex region, groundwater has been recharged by three important mechanisms: direct infiltration of rai

A COMPARISON has been made between the catalytic labelling1 of organic compounds with deuterium and tritium and radiation-induced techniques2. Of fundamental importance in deciding the choice of method, particularly for tracer applications, is the po

The value of labeling organic molecules with deuterium and/or tritium in a one-step procedure is now well established for structure determination by mass spectrometry [1], spin decoupling in nuclear magnetic resonance spectroscopy [2], evaluation of

A simple procedure for the conversion of 14C NBS oxalic acid standard to benzene without direct combustion or wet oxidation is reported. Fractionation in the synthesized benzene was not detected.
