“…Geoaccumulation Index values can be efficiently applied to determine sediment quality (Singh et al 2020). Different metals in sediments may be due to the increased particulate matter with relatively unpolluted sediments combinations (Li et al 2022;Shou et al 2022). The study's Contamination factor (Cf) shows that each metal causes low contamination, except for the heavy metal Pb, which is included in moderate contamination.…”

Abstract. Rozirwan, Khotimah NN, Putri WAE, Fauziyah, Aryawati R, Damiri N, Isnaini, Nugroho RY. 2023. Environmental risk assessment of Pb, Cu, Zn, and Cd concentrations accumulated in selected mangrove roots and surrounding their sediment. Biodiversitas 24: 6733-6742. Mangroves as the largest coastal ecosystem can accumulate heavy metals from their environment. This study aimed to evaluate the environmental risk associated with heavy metal pollution accumulated in the roots of mangroves and the surrounding sediments. The mangrove roots consisted of three species Sonneratia caseolaris, Rhizopora apiculata, and Xylocarpus granatum, collected from three observation stations within the Payung Island mangrove ecosystem in South Sumatra, Indonesia. The concentrations of heavy metals were determined using atomic absorption spectrometry. Statistical analysis employed one-way Analysis of Variance (ANOVA). At the same time, ecological risk assessment utilized the Bioconcentration Factor (BCF), Geoaccumulation Index (Igeo), Contamination factor (Cf), and Pollution Load Index (PLI). The highest sediment concentrations of heavy metals at station 3 were 12.786±0.26 mg/kg for Pb, 10.413±0.011 mg/kg for Cu, 42.752±0.053 mg/kg for Zn, and Cd was not detected. In mangrove roots, the highest concentrations were found in S. caseolaris, with 2.596±0.002 mg/kg for Pb and 11.881±0.015 mg/kg for Zn, while X. granatum exhibited 8.850±0.011 mg/kg for Cu and 0.160±0.020 mg/kg for Cd. BCF values <1 were categorized as exclusion, Igeo<0 indicated non-contamination, Cf<1 signified low pollution, and PLI<0 denoted an unpolluted status. Based on the results, the quality of the mangrove ecosystems affected by heavy metal pollution is currently considered safe regarding environmental risk assessment.

“… 32 Heavy metals, known for their high toxicity, long-lasting presence, and bioaccumulation, have a significant effect on the quality and safety of water. 33 Heavy metals are a group of elements characterized by their high density and atomic weight that can be detrimental to both human health and environment. Heavy metals have become a significant problem for water pollution in recent times, raising public concern for the environment and human health, and are considered a major global concern currently.…”

“…Rivers, which deliver approximately 20 billion metric tons of transported sediment to oceans annually, play a key role in Earth's surface processes, marine sedimentation, and biogeochemical cycles in oceans [1,2]. Anthropogenic inputs of pollutants can considerably change the composition of river waters and sediments [3].…”

Heavy metals as environmental pollutants can have natural or anthropogenic origin. To determine the river sediment pollution status, it is crucial to have appropriate reference samples, free of anthropogenic impact, and natural reference samples should be used wherever and whenever possible. The collection of reference samples should be performed in the vicinity of the research area in a place that belongs to the same geological environment and is undisturbed by human activity. The main purpose of this study was to compare concentrations of heavy metals from different rivers with background values to show that the usage of natural background values is the best option when assessing pollution status, but also to underline that the natural background values have to correspond to the analyzed sediments. In this study, 5 river sediments from Sava, 17 from Great War Island (GWI), 11 from Danube, 24 from Tisa, 47 from Tamiš, and 11 from Timok were evaluated relative to reference samples from the Sava and Tisa Rivers. The results indicate that geological origin has a strong influence on the content of heavy metals in river sediments, primarily regarding concentrations of Ni and Co. Furthermore, Tamiš, Tisa, Sava, and Danube sediments are under strong anthropogenic influence.
