The groundwater Cr(VI) concentrations ranged between 1.9E-5 mM and 0.04 mM, while the NO3− concentrations ranged between 0.5 mM and 3.9 mM.56 p.application/pdfengcc-by-nc-nd (c) Elsevier B.V., 2020http://creativecommons.org/licenses/by-nc-nd/3.0/esDesnitrificacióIsòtopsArgentinaDenitrificationIsotopesArgentinaCharacterisation of the natural attenuation of chromium contamination in the presence of nitrate using isotopic methods.
