Metals Sediments River - Europe PMC

Tracking the origin of trace metals in a watershed by identifying fingerprints of soils, landscape and river sediments.

For a better watershed and river water quality management, it is imperative to determine the spatial distribution of soil trace-elements and the contribution of various sources to the sediment yield. More attention has been paid to comprehensive reviews of sediment sources and soil trace-elements in connection with suspended sediment production until now. The current research was designed to investigate the spatial distribution of soil trace-elements, measuring the sediment sources apportionment, and connecting the landforms to polluted soils. For spatial modeling, a total of 79 soil samples with different Nemerow index values were considered. For eight rainfall events, unmixing technique was used to determine the relative contribution of landforms to eight rainfall events. RF had the highest results with an accuracy of 83%, according to the results of the soil trace-element mapping report. With a GOF of 0. 72 in early-winter events, the landform 'plain' made the largest contribution to sediment yield, leading to the highest value in sediment yield.

Toxicity of heavy metals in water, sediments and different body organs of fish Labeo rohita (rohu) at head Balloki, river Ravi, Lahore Pakistan

The health risk implications of the presence of heavy metal-contaminated water and fish collected at Head Balloki were determined in the current study. This research revealed that the Concentration of chromium Cr was higher than that of Nickel Ni in water Cr > Ni. Cr, on the other hand, Chromium Cr in Labeo rohita's fish organ was higher than Ni in Gills Cr > Ni, and Ni's concentration was higher than the chromium Cr in Liver Ni> Cr. Water and heavy metals and metal levels in fish must also be investigated by scientists.

Spatial distribution of heavy metals and Ecological Risk Assessment for the main sub-branches (Rayahs) sediments of Nile River, Egypt

According to the contamination degree and potential ecological risk indices, the risk for El-Rayahs sediments increases northward; however, most sites did not show significant pollution or did not find any evidence of contamination, except the northern stretch of El-Behery, which is a high-polluted area with elevated ecological danger, although some sites did not display significant pollution or absence traces of contamination.

Trace metals accumulation on modern sediments from Po river prodelta, North Adriatic Sea.

New data on sedimentary regime and human migration in the Po river prodelta region has been published by Trace Metals, key elements, and radionuclides research on EL-C01 sediment core. The decline of heavy metal content from the second half of the 1980s is likely as a result of Italian Law 319/76 and anti-pollution environmental regulations affecting industrial and urban emitters.
