“…For example, the mean concentration of Zn and Hg exceeded the threshold value of the interim sediment quality guidelines. These results are in agreement with other studies reporting that sediments are the main sink for heavy metals in the aquatic environment (Wei et al, 2023), where sediment quality could reflect the degree of environmental contamination status on a longer time scale (Qian et al, 2021). In addition, unlike other pollutants, metals do not biodegrade and are toxic and bioaccumulative (Zeng and Wu, 2013;Ranjbar et al, 2017;Sojka et al, 2022).…”

High Andean rivers are fragile ecosystems in the face of various threats, including heavy metal contamination. The objective of this study was to evaluate the potential ecological risk of heavy metals in surface sediment of lotic systems in the central region of Peru. Composite samples of surface sediments were collected from the Chía and Miraflores rivers and the concentrations of heavy metals were determined. The ecological risk analysis was carried out based on the contamination indexes and confirmed by the modified degree of contamination (mCd). The concentration of heavy metals in the sediment of the Chía river was in the following descending order: Fe > Mn > Zn > V > Pb > Cr > Ni > Cu > Mo > Hg, y en el río Miraflores fue: Fe > Mn > Zn > Ni > V > Cr > Cu > Pb > Hg > Mo. The mean concentration of Cu, Cr, Fe, Mn, Mo, Ni, Pb, and V in the sediment samples in both rivers did not exceed the threshold values of the continental crust concentration, nor the interim sediment quality guidelines of the Canadian Council of Ministers of the Environment. However, the mean concentration of Hg exceeded the guideline values in the Miraflores river and the likely effect (0.7 mg.kg−1) adverse effects. The values of the enrichment factor (EF), contamination factor (CF), geoaccumulation index (Igeo), and pollution load index (PLI) indicated low contamination in the sediments of the rivers studied, being confirmed by the modified degree of contamination (mCd). Finally, the risk assessment showed that heavy metals in the sediments presented a low potential ecological risk.

A key aspect of climate change is its impact on river water quality. Most research focuses on the impact of physiochemical parameters on water quality. However, the long-term shifts in temperatures and weather patterns coupled with anthropogenic activities play a significant role in river contamination. Metals are known to have toxic effects and environmental persistence. This study evaluated the heavy metal content of the Kaap River, where mining and agriculture are the primary land use. A 7-year study was conducted to investigate the seasonal relationship between heavy metals and physiochemical parameters (EC and pH). Fe, Al, As, and Mn concentrations were analysed in a laboratory accredited by the South African National Accreditation System (SANAS). The Python package Seaborn was used to generate heat maps for improved data visualization. Seasonal and temporal fluctuations had a combinatorial impact on Mn, Fe, and Al levels of the river. However, As levels were unaffected. The pH of the rivers was within the recommended range, despite flow regime, seasonal, and time-dependent fluctuations. Seasonal and temporal variations were also observed for EC, with the highest value of 42.35 mS/m being recorded during the winter of 2022, exceeding the recommended threshold of 30 mS/m. The correlation analysis revealed positive and significant correlations for the EC/pH and Al/Fe combinations and a weak degree of association for other parameters (P < 0.05). A permanent monitoring of water quality is required to ensure sustainable livelihoods and the safety of Kaap River water, which is subject to significant heavy metal fluctuations over time.
