Ekkdopgbht6rehghvmsik1nyjnolz1txmis07zcbuievxnxa Finally, our research indicates that cu isotopes could be a powerful tool for tracing pollution sources if the isotope ratios of the potential sources are distinct and different from those of soil samples. thus, a systematic analysis of all the end member cu isotope signatures for each case is a prerequisite for tracing pollution via cu isotopes. The cu contents and isotopic compositions of the soils and end member samples are listed in table 1.the cu contents of the hemenkou soils (hs) vary from 21.86 to 24.13 μg g, with an average of 22.72 μg g (n = 3), which are close to the soil background value of cu in sichuan province (31 μg g, long et al., 2021).

Alfabetul Cuvinte Care Incep Cu Litera E Youtube Among the massive non traditional isotopes, using stable cu isotopes to investigate pollution sources in complex wild environments is a topic of debate. cu has two stable isotopes, 63 cu and 65 cu, with abundances in nature of 69.2 % and 30.8 %, respectively (william et al., 1964). previous research has shown that significant cu isotopic. The plot of δ 65 cu and 1 cu demonstrates that cu of the polluted soils was from three end members: the smelting fly ash, the vehicle exhaust, and the background soils. based on the mass balance model, we calculated that the fly ash from smelting was the major anthropogenic source, contributing approximately 29 % of cu contamination in soils. Doi: 10.1016 j.scitotenv.2023.167114 corpus id: 262030016; application of cu isotopes to identify cu sources in soils impacted by multiple anthropogenic activities. @article{xia2023applicationoc, title={application of cu isotopes to identify cu sources in soils impacted by multiple anthropogenic activities.}, author={bo xia and yi huang and xiangjun pei and chao liu}, journal={the science of. The xanes spectra collected for cu species in cc@cnc showed similar adsorption characteristics with those of cu foil, indicating the predominant existence of cu in its elemental form cu 0 within the co–cu alloy) (fig. 2 e, red circle). despite the detection of cu–n o coordination, it was demonstrated that cu sas were significantly less.
