Web7 apr. 2024 · Anthropogenic Zn is generally isotopically lighter than the lithogenic source (δ 66 Zn litho = ∼0.3‰) (Little et al., 2014). As a result, an enrichment of Zn is generally associated with an overall trend toward low δ 66 Zn in contaminated marine sediments and soil profiles (Araújo et al., 2024; Bigalke et al., 2010; Nitzsche et al., 2024).
