“…For instance, Hahn et al (2018) indicates that sediments become contaminated due to the release of metals from soils by leaching and soil erosion processes. The results found are supported by other studies that refer that Cu, Pb, and Zn tend to be rapidly diluted and transported long distances once they are released into the water body and finally deposited in the sediment (Zhuang et al, 2021;Nagarajan et al, 2023). These findings also indicate that Hg is the main contributor to heavy metal pollution in the Miraflores river (Zahra et al, 2014;Ke et al, 2017;.…”

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.

“…Owing to their lower mobility in a variety of environments and lesser residence times in seawater (Cox, Lowe, & Cullers, 1995;Taylor & McLennan, 1985), the trace elements and rare earth elements (REEs) are useful in determining the provenance and tectonic settings. Certain immobile trace elements (e.g., V, La, Th, Zr, Hf, Sc, Co, Ni, Cr, and REEs) are used to identify the most likely provenance of a clastic sedimentary rock (Asiedu, Agoe, Amponsah, Nude, & Anani, 2019;Bhatia, 1985;Bhatia & Crook, 1986;Chen et al, 2019;Cullers, 1995;Cullers & Berendsen, 1998;Cullers & Podkovyrov, 2002;Garver & Scott, 1995;Khan, Sarma, Somasekhar, Ramanaiah, & Ramakrishna Reddy, 2019;Ma et al, 2019;Madhavaraju et al, 2020,b;McLennan, 1989;Nagarajan et al, 2014Nagarajan et al, , 2015Nagarajan et al, , 2019Nagarajan, Armstrong-Altrin, et al, 2017;Nagarajan, Roy, et al, 2017).…”

Geochemistry of the Palaeocene‐Eocene Upper Kelalan Formation, NW Borneo: Implications on palaeoweathering, tectonic setting, and provenance

The stratigraphic records of Palaeocene-Eocene are studied with interest as they encompass significant high-resolution information on the environmental and climatic signals. Here, we present whole-rockgeochemistry, mineralogy, and petrography of the turbiditic sedimentary rocks of the Upper Kelalan Formation, NW Borneo, and constraints on palaeoweathering, tectonic setting, and provenance. These are finemedium-grained, poor to moderately sorted, angular to sub-rounded litharenites with lesser occurrences of arkose, wacke, and Fe-sandstone. The dominant proportion of monocrystalline and polycrystalline quartz, followed by K-feldspar and plagioclase and minor amounts of lithic fragments, zircon, etc., with nil-appreciable quantities of clay occur in these rocks. Chemical weathering indices (CIA, CIW, and PIA) values and A-CN-K plot show that the source area has undergone a moderate to an intense degree of chemical weathering and also influenced by the recycling effect. The majority of the sediments are derived from the felsic source area (i.e., granites) with some minor input from the metasedimentary/metamorphic terrain. Based on the geochemical ratios and discriminant diagrams, it is determined that the Schwaner Mountains and its metamorphic group of rocks were the principal provenances with some input from West Borneo Group of rocks. Our data suggest the sediments were deposited initially in an active continental margin setting during the Palaeocene that may have shifted to a passive margin setting during the Eocene age.

Mangrove roots play an important role in reducing heavy metal pollution in their surroundings. This study aimed to assess the bioaccumulation and ecological risk assessment of heavy metal pollution in mangrove roots. Mangrove root samples consisting of two species (Avicennia alba and Excoecaria agallocha) were collected from two observation stations in the mangrove ecosystem of Payung Island, Banyuasin District, South Sumatra, Indonesia. Heavy metal concentrations were measured by atomic absorption spectrometry. Then, statistical analysis was carried out by one-way analysis of variance (ANOVA). Ecological risk assessment used the bioconcentration factor (BCF), geoaccumulation index (I geo ), contamination factor (Cf), and pollution load index (PLI). On the basis of the results, the highest sediment heavy metal concentration at station 2 was Pb amounted to 13.57 ± 0.46 mg/kg, and Cu amounted to 11.08 ± 0.38 mg/kg. In turn, the highest heavy metal concentration of mangrove roots in E. agallocha species for Pb amounted to 2.89 ± 0.033 mg/kg and A. alba for Cu amounted to 10.57 ± 0.38, BCF was classified as exclusion (BCF < 1), except for the BCF of Cu station 1, which was classified as hyperaccumulator (BCF > 1). Igeo shows that the level of pollution is not contaminated (I geo < 0), and Cf shows low pollution (Cf < 1), except Cf Pb station 2 is classified as moderate pollution. Conversely, PLI is included in the category of not polluted (PLI < 0). Mangrove roots play an important role in reducing heavy metal pollution in the surrounding area. Therefore, an in-depth understanding of heavy metal dynamics can be the basis for designing effective coastal environmental conservation strategies.
