| 1 | Chemical and spectroscopic characterization of humic substances from sediment and riparian soil of a highly polluted urban river (Suquía River, Cordoba, Argentina)显示文摘The Suquía River,the largest urban river in C ordoba(Argentina),has been severely polluted for decades.Actions must be taken to restore its environmental quality by managing riparian zones for increased water-self purification.The current study aimed to characterize organic matter(OM)dynamics and humic substances(HS)spectrochemical properties along the lower-middle basin of the Suquía River.Riparian soil(0e20 cm)and sediment(0e10 cm)samples were collected from a reference location(S1)and four polluted sites(S2eS5)during a low-flow period.The contents of soil and sedimentary OM and HS fractions were analyzed by wet oxidation,as well as HS Fourier transform infrared(FT-IR)and ultravioletevisible(UVeVis)spectrochemical properties.The OM and HS fractions from riparian soil were high upstream of C ordoba City(S1 and S2,50.2e50.4 g/kg OM)and within a 50 km downstream location(S5,30.9 g/kg OM)owing to a surplus of fresh plant biomass-carbon(C)inputs.Highly heterogeneous sediment samples did not show any significant differences among sites(P>0.05).The lowest values of the ratio of absorbances at 465 and 665 nm(E4/E6)(1.78)and the Δ log K(0.15)coefficient(a measure of HS maturity degree)were obtained downstream of C ordoba City,for both riparian soil and sediment,indicating that HS were enriched by more condensed aromatic structures within highly degraded portions of the river.All samples exhibited similar IR spectra,implying overlapping recalcitrant-C structures at the functional group level,but with different absorbance intensity.Data from the current study constitute a baseline for understanding the chemical nature of HS from sediment and riparian soil along the Suquía River and can be used as a reference for future studies tracking OM compositional changes over time. | Carolina Merlo Carolina Vázquez Ana Graciela Iriarte Carlos Matías Romero | 2020 | International Journal of Sediment Research2020，35，3： | 3 |
