Spatial Distribution of Heavy Metals in Near-Shore Marine Sediments of the Jeddah, Saudi Arabia Region: Enrichment and Associated Risk Indices

In recent decades, Red Sea coastal growth has accelerated, contributing to an increase in the anthropogenic heavy metal content in sediments. A total of 80 surficial sediment samples were collected from the shallow waters off the eastern Red Sea coast near Jeddah, Saudi Arabia's southern Red Sea coast. The results revealed that the concentrations of these metals in the studied sediments remained in this order: Pb > Mn > Zn > Cu > Ni. Indices were derived from the measured metals to establish baselines for the area and determine specific metal enrichment by location along the Jeddah coast, including Geo-accumulation indices, Enrichment Factors, Contamination Factors, Pollution Load Indices, Potential Ecological Risk Indices, and Potential Toxicity Response Indices. 30% of the Southern location stations are considered moderately to heavily polluted, according to the Igeo results.

Impact of heavy metals on water, fish ( Cyprinus carpio ) and sediments from a water tank at Tumkur, India

Cyn > Cd > Cr > Fe, the water-soluble fractions of heavy metals correlated positively with their total concentration, showing the following pattern of bioavailability: Zn > Cd > Cu > Cr > Fe. The mean values of all types of collected samples were correlated with the corresponding mean values in a control tank, according to the corresponding mean values. Pb > Cu Ni > Ni > Cd> Zn, Cr > Cr > Cd> Pb> Cd > Cd> Cd > Zn, Cd> Cd > Cr > Cr > Pb > Pb> Ni > Pb > Pb> Ce Cd> Cd > Cd > Zn > Cd > Cd> Zn > Pb> Cd > Pb> Ni > Ni > Pb> Cdoutput: Ni > Ni > Ni > Cd > Ni > Cd > Cd > Ni > Cd > Cd > Cd > Cd > Cd > Cd > Cd > Cd > Cd > Cd > Cd > Cd > Pb > Cd > Cd > Cd > Cd > Cd > Cd > Ni > Cd > Cd > Cd > Cd > Zn > Cd > Cd > Cd > Cd > Cd > Cd > Zn > Pb > Cd > Cd > Zn > Pb > Cd > C Although Cyprinus carpio is widely used for human consumption, there is a growing health risk that these metals could make their way into human food chains.

Heavy Metals Contamination in the Surface Sediments of Talar River, North of Iran

Background and Purpose: The contamination by a potentially harmful chemical element is a common environmental problem in worldwide rivers. PTEs were discovered in sediments of Talar River, one of the main rivers in the Sothern Caspian Basin, according to this report. Using a Van-Veen grab sampler, the sediment samples were collected from top 0–5 cm of surface sediment in Talar River's main channel and floodplain. To find potential correlations between the observed variables and source identification, principal component analysis was used to investigate potential correlations. Results: The average concentration of all elements except Mo was found to be higher than the average concentration of elements in the upper continental crust. Conclusion:It was found that sediments in Talar River were now polluted slightly from local anthropogenic sources in the basin, which may have detrimental effects on both environmental and health conditions.
