dc.description.abstractAiming at assessing the effect of dredging activities on the levels of metals in Bilbao Port (northern Spain), dissolved and labile metal concentrations in the water were concurrently measured, before, during, and after dredging activities by spot sampling and Diffusive Gradients in Thin-films (DGTs) passive samplers, respectively. Most of the dissolved metal results were below the quantification limits (Cd, <0.06-0.26 <mu>g/L; Co, <5 <mu>g/L; Cu, <5-15 <mu>g/L; Fe, <10-48 <mu>g/L; Mn, <10-22 <mu>g/L; Ni, <2.6-7 <mu>g/L; Pb, <0.39-0.8 <mu>g/L; Zn, <9-24 <mu>g/L). In contrast, DGT results for all sampling times and stations were obtained (Cd, 0.02-0.12 mu g/L; Co, 0.08-0.15 mu g/L; Cu, 0.5-2.8 mu g/L; Fe, 1.0-3.6 mu g/L; Mn, 4.7-23.5 mu g/L; Ni, 0.5-0.9 mu g/L; Pb, 0.15-0.28 mu g/L; Zn, 2.6-7.2 mu g/L), enabling to determine those metals affected by dredging. Only labile-Pb concentration surpassed momentarily the DGT-Environmental Quality Standard, enabling to rule out biological effects on biota. DGTs are a promising technique for facilitating decision-making during dredging operations.-
