“…Cd levels in the Passur river varied from 0.80 to 2.70 mg/kg, according to Rahman et al (2011). In the Yangtze River Estuary, China, Fan et al (2020) and Wang et al (2020) found decreased levels of Cd. In Tokyo Bay, Japan, Fukushima et al (1992) found 0.996 mg/kg Cd.…”

The study area was selected in the Rupsha river basin and the sediment samples were collected to determine trace metal concentrations of As, Pb, Cd, and Cr along with biological effects, and potential ecological and human health hazards for adults and children. The concentrations of trace metals were detected from sixty composite sediment samples using an Atomic Absorption Spectrophotometer (AAS) following some sequential analytical procedures. The mean concentrations of trace metals were organized in the descending order of chromium (Cr) (43.2 mg/kg) > lead (Pb) (29.21 mg/kg) > arsenic (As) (5.18 mg/kg) > cadmium (Cd) (1.8 mg/kg). The current study highlighted that metals were attributed to the riverine sediments from natural sources and other anthropogenic sources, particularly from various industries. Based on the effect-range classifications of threshold effect concentration (TEC) and probable effect concentration (PEC), the trace metal concentrations can impact on the sediment-dwelling organisms occasionally especially for Cr, Cd, and Pb. That is, the concentrations had negative biological consequences on aquatic creatures. The assessed potential ecological risk of Cd offers a significant risk to the aquatic ecosystem, whereas As, Cr, and Cd were in low-risk. Most of the sites of the study area were within the range of moderate risk, indicated by the risk index (RI) values. Furthermore, the applied sediment quality indices, geo-accumulation index (Igeo) indicated that sediment was contaminated by Cd whereas contamination factor (CF) denoted that the sediment of the study area was moderately polluted by Pb. However, pollution load index (PLI) revealed that the study area was polluted for cumulative sence especially in winter season. The age-group risk index (HI) was much lower than the threshold limit of 1, showing that the pollution had no non-carcinogenic risk effect. Total carcinogenic risk (TCR) was less than one-tenth of a percentile. For the sake of human and environmental health, proper monitoring of metal element attribution and strict regulation are required to lessen trace metal pollution.

“…In addition, Fe was significantly correlated with Al ( p < 0.01). Al and Fe are mainly found in fine-grained sediments and clastic minerals, and the strong correlation of heavy metals with Al and Fe suggests that these heavy metals are less influenced by anthropogenic activities and that they may be of the same origin as Al and Fe 42 .…”

Dongting Lake is one of the most important inland freshwater lakes in China. To investigate the spatial distribution and seasonal variation characteristics of heavy metals (Cr, Co, Cu, Zn, Cd, and Pb) in the lake, 53 surface sediment samples were collected in the East Dongting Lake (ED Lake) in the wet and dry seasons. Results show Cr, Co, Cu, Zn, Cd, and Pb contents were 1.7 (1.9), 1.8 (2.0), 2.9 (3.0), 1.9 (1.9), 11.7 (13.1), and 2.0 (2.2)-fold of their geochemical soil background values of Hunan province (China) in the wet (dry) season. Spatial and seasonal heterogeneity could be found in the distribution of Cr, Co, Cu, Zn, and Pb in the surface sediments. The enrichment factor (EF) suggested that Cd has reached severe enrichment in the sediment. The result of the geo-accumulation index ($${I}_{geo}$$ I geo ) indicated that Cr, Co, Cu, Zn, and Pb were at levels corresponding to low contamination, and moderately to highly polluted with Cd. Multivariate statistical analysis including pearson correlation analysis and principal component analysis was used for the identification of potential sources of the heavy metals in the sediments. The results showed that Cu, Zn, and Pb from the sediments of the East Dongting Lake in the wet and dry seasons were possibly anthropogenic sources, such as emissions from mining and smelting while Al, Fe, and Cr are attributed for natural sources. Cd enrichment in the sediments is influenced by both natural factors, and human activities in local areas.

“…The Contamination factor (CF) and the degree of contamination (CD) were used to assess the anthropogenic effect on sediment chemistry and to calculate the concentration of metals in the sediment sample towards uncontaminated baseline values metal (Taylor and Mclennan (1995); Stamatis et al, 2019;Wang et al 2020). As reported in Hakanson, (1980), CF is the ratio for specific metals in soil and its background.…”

“…Primordial radionuclides and potentially toxic elements in coastal sediments are capable of providing some valuable information regarding the source, components of transport and the nature of marine environments, where it may be predicted as a serious environmental concern (Khan et al 2021). Geochemical cycling of different elements in the aquatic environments has significant ecological effects on food-web driven pollution that will enter the whole biota, which has been significantly altered by the possibility in coastal regions, urban emissions, and industrial activities worldwide (Magesh et al 2011, Wang et al 2020. Environmental pollution measurement in the marine environment is determined by the amount of seawater residual particulate matter, rate of particular primordial radionuclides in the sediments and possibly radioactive materials (Inigo Valan et al 2020;.…”

The present study focuses on the environmental radioactivity and multi-risk assessment of nearshore sediments as a source of marine pollution along the Bay of Bengal. The study examines the distribution of primordial radionuclides concentration using a Na(I)Tl detector-based gamma-ray spectrometer and Potentially Toxic Elements (PTE) through atomic adsorption analysis. Further, the data obtained and characterization radiological risks, ecological threats, and assessing the spatial distribution of toxic elements in nearshore sediments as a proxy for marine contamination. The active concentration of primordial radionuclides such as 238U, 232Th and 40K were found in ranged from ≤ 3 to 68 (11.4), ≤ 9.5 to 142.7 (41.2) and 85.2 to 603.4 (362) Bq kg-1. Results show that the concentration of the average radionuclides is less than suggested by UNSCEAR ranges. The concentration of potentially toxic elements (Fe, Cr, Ni, Pb and Zn) was higher in deeper water depth. This study exposes that the primary control of such elements is mud distribution. A decreasing order has been seen as follows by the ecological risk index of individual elements: Cu > Pb > Ni > Cr > Zn. The significant Pb, Cu and Zn concentration was polluted at most stations, possibly contributing the regional and terrestrial sources such as industrial activity, urban drainage, manufacturing, and farming. This research suggests that anthropogenic behaviours in nearby land are the source of the deposition of metals and radionuclides in coastal and marine sediments.
