Abstract The linkages between nitrogen cycling, isotopes, and environmental properties are fundamental for reconstructing biogeochemistry. While the impact of ocean redox changes on isotopes is relatively well understood, it poorly known how responds to in pH salinity. To fill knowledge gap, we explore effects these parameters using a well-controlled set samples from Carboniferous–Paleogene lak...

The average time of input water needs to recharge the groundwater basin and reach a catchment outlet, whether it follows vertical or horizontal flow direction, is known as mean residence (MRT). This study aims identify theory concepts estimation MRT in well using environmental isotope technique. For this purpose, spatiotemporal data oxygen-18 precipitation Erbil city were taken from Global Netw...

Groundwaters are the primary source of drinking water for half world’s population. They represent about 97% available freshwater resources, being extensively abstracted and contaminated in many parts world. Among groundwaters thermal waters, a health, well-being, major touristic attraction (geoheritage), also providing link to natural environment. Therefore, it is strongly important manage such...

The article presents the results of a study on the bioaccumulation abilities of Polysiphonia fucoides, a red algae specific to the southern Baltic Sea, towards (of) gamma emitting isotopes. A laboratory experiment was carried out to determine changes in the activities of some isotopes-54Mn, 57Co, 65Zn, 110mAg,113Sn, 134Cs, 137Cs and 241Am-occurring in P. fucoides exposed to a seawater medium co...

The advent of magnetic sector inductively coupled plasma-mass spectrometry (ICP-MS) allows rapid, accurate, and precise measurement of lead isotopes in environmental and biological samples at a lower cost than traditional methods. This may increase the feasibility of including lead isotope measurements as a routine tool to identify household sources of lead exposure to children. Here, we presen...

Stable isotopes in wood cellulose of tree rings provide a high-resolution record of environmental conditions, yet intra-annual analysis of carbon and oxygen isotopes and their associations with physiological responses to seasonal environmental changes are still lacking. We analyzed tree-ring stable carbon (δ13C) and oxygen (δ18O) isotope variations in the earlywood (EW) and latewood (LW) of pin...

We discuss in detail a model which makes definite predictions for the fractionation of isotopes in sputtered material. The fractionation patterns can be nonlinear, and the pattern for a particular set of isotopes depends on the chemical matrix within which those isotopes are contained. Calculations are presented for all nonmonoisotopic elements contained in the minerals perovskite, anorthite, a...

Short lived Ra isotopes have been produced at the TRIμP facility in inverse kinematics via the fusion-evaporation reaction Pb+C at 8 MeV/u. Isotopes are separated from other reaction products online using the TRIμP magnetic separator. The energetic radium (Ra) isotopes at the exit of the separator were converted into low energy ions with a thermal ionizer. Ra isotopes have been identified by ob...
