Cu, Cd, Pb and Zn are frequently studied metals (Goodyear and McNeill 1999), as elevated levels might be toxic to organisms. Zn and Cu are essential trace metals; whereas, Cd and Pb are in general considered non-essential (e.g. Rainbow 2002; Hejna et al. 2018). P is an essential macronutrient; whereas, Se is an essential trace nutrient. We ...

The variation in δ 65 Cu AE647 (δ 65 Cu max-min) was larger than that of δ 66 Zn IRMM3702 (i.e., δ 66 Zn max-min), and the isotope values of Zn and Pb (206 Pb/ 207 Pb) tended to increase with the concentrations of these elements. Meanwhile, the fine RDS particles (< 63 µm) had similar Cu, Zn, and Pb isotopic compositions to those of TSS.
