“…In the present study, elevated concentrations of dissolved Mn were notably also associated with elevated DOC concentrations, especially at the creek sites. As DOC can bind to metals and reduce their toxicity to Australian freshwater fauna (Holland et al, ; Holland, Duivenvoorden, & Kinnear, ), it is possible that any impacts from elevated dissolved Mn may have been ameliorated.…”

Worldwide, agricultural activities are associated with environmental impacts including riparian degradation and increased waterway pollution. The Fitzroy Basin of Central Queensland lies within the Brigalow Belt Bioregion, which is currently experiencing the highest rates of tree clearing in Australia driven by grazing activities, and this is likely to increase riparian degradation. Local riparian condition, however, has not been consistently monitored within the Fitzroy Basin, and its relationship with water quality has not been well established. This study assessed riparian condition of waterways in the Fitzroy Basin using two established scoring methods (the Rapid Appraisal of Riparian Condition and the Australian Rivers Assessment System Habitat Assessment) and statistically investigated the relationship between stream water quality and local riparian condition. Twelve sites in six waterways were sampled four times over two years, during ambient (nonflood) conditions. Upstream creeks with poorer riparian condition had elevated dissolved organic carbon (DOC), dissolved manganese, sulfate, and total nitrogen (TN) concentrations. High concentrations of these water quality variables were associated with poor local riparian scores in principal components analysis. Dissolved manganese and sulfate were included in the multiple regression model for riparian scores (r values: 0.83 to 0.86; p < 0.001), and DOC and TN were very significantly negatively correlated with riparian scores (r values: −0.55 to −0.69; p < 0.001). Overall, the results suggest that protecting riparian vegetation in the Fitzroy Basin and restoring degraded riparian zones could aid in improving water quality in waterways within this region.

“…Mining of sulfidic ore can generate acid mine drainage (AMD) containing high concentrations of Al, Fe, Mn, and other potentially toxic metals (As, Cd, Cu, Ni, Pb, and Zn; Moore & Luoma, 1990), all of which can impair aquatic ecosystems (DeNicola & Stapleton, 2002). Toxicity-modifying factors (e.g., pH, alkalinity, and dissolved organic carbon [DOC] concentration) can account for variations in aquatic metal toxicity (e.g., Fulton & Meyer, 2014), particularly in waters impacted by AMD (Holland et al, 2013(Holland et al, , 2014a(Holland et al, , 2014b(Holland et al, , 2014cSoucek et al, 2000). Tools such as the Biotic Ligand Model (BLM) and extensions of the Windermere Humic Aqueous Model (e.g., WHAM-F TOX ) have been developed to predict the effect of water composition on the aquatic toxicity of cationic metals (Tipping & Lofts, 2013).…”

Dissolved copper (Cu) can contribute to toxicity in aquatic systems impacted by acid mine drainage (AMD), and its bioavailability is influenced by aqueous complexation with organic ligands that predominantly include fulvic acids (FAs). Because the geochemical fractionation of FAs that accompanies sorption to hydrous aluminum oxides (HAOs) and hydrous iron oxides (HFOs) can alter Cu complexation with FA, we investigated FAs isolated from three categories of water (pristine, AMD, and in situ‐fractionated mixtures of pristine and AMD collected at stream confluences) in three mining‐impacted alpine watersheds in central Colorado, USA. We also conducted geochemical fractionation of field‐collected FAs and Suwannee River FAs by precipitating HAOs and HFOs in the laboratory. Spectral properties of the FAs (e.g., UV‐VIS absorbance) were altered by geochemical fractionation, and in acute toxicity tests with an aquatic invertebrate (Daphnia magna) Cu was more toxic in the presence of in situ‐ and laboratory‐fractionated FAs (median effect concentration [EC50] 19–50 µg Cu L−1) than in the presence of nonfractionated FAs (EC50 48–146 µg Cu L−1). After adjusting for the strain‐specific sensitivity of our D. magna, we improved the accuracy of Biotic Ligand Model predictions of Cu EC50 values for AMD‐related FAs by using an “effective dissolved organic carbon” based on spectral properties that account for among‐FA differences in protectiveness against Cu toxicity. However, some differences remained between predicted and measured EC50 values, especially for FAs from AMD‐related waters that might contain important metal‐binding moieties not accounted for by our measured spectral indices.

The dissolved metal concentrations have been assessed for Co, Cr, Cu, Fe, Mn, Ni, V, Zn, Ca, Mg, and Cd, and their complex compounds with humic substances (Me-HS complexes) in river waters of the Upper Amur basin using the inductively coupled plasma-mass spectrometry technique. The study shows an increase in the amount of Me-HS complexes from the southwestern steppe and forest-steppe to the northeastern mountainous taiga areas. In alkali waters of the steppe and forest-steppe areas with low concentrations of HS, the amount of Zn-HS complexes increases considerably. The observed general regularity in the distribution of metals is as follows: Fe > Cu ≥ Zn > Cr > V > Ni > Сo ≥ Mn > Ca > Mg > Cd. In acidic and neutral waters of the taiga rivers containing high concentrations of HS, 50% of metals are complexed with HS. Metals are arranged in the following order: Fe > Cu > Ni > Cr > V > Zn > Сo > Mn > Ca > Mg > Cd. Quantitative characteristics and a correlation matrix show that Me-HS complexes are dominant among toxic metals (Ni, Cu, Zn, Cr, Fe, and V) and account for 40-55% of total dissolved forms. This allows us to evaluate the important role of Me-HS complexes in satisfactory ecological situation in rivers of the Upper Amur basin. However, toxicity may increase in separate watercourses (Chita and Argun rivers) due to high concentrations of dissolved Zn, Cu, and Cr, which indicate local and transboundary sources of pollution.
