Quantification of Lambda (Λ) in multi-elemental compound-specific isotope analysis

Abstract

The parameter  represents dual element stable isotope data Two conventions for quantifying  give different  values Linear regressions of delta values in a dual element plot overestimate  We show that only the ln-transformed isotope ratios should be fitted

Transformation and stable isotope fractionation of the urban biocide terbutryn during biodegradation, photodegradation and abiotic hydrolysis

“…Given uncertainties correspond to the 95 % confidence interval (CI) of the slope of the linear regression. Λ N/C values were derived using the York regression, accounting for uncertainties in C and N isotope measurements (Höhener and Imfeld, 2021;Ojeda et al, 2019) according to:…”
