Total metals concentrations, Geoaccumulation index (Igeo), Pollution load index (PLI), degree of contamination (DC) and sediment quality guidelines (SQGs) were used to assess heavy metals contamination status and ecological risk in the sediments from the Libyan Mediterranean coast. The distribution pattern of heavy metals in the sediment follows the sequence: Fe>Pb>Mn>Ni>Zn>Cr>Cu>Co>Cd. Over th...

There is currently a wide variety of methods used to evaluate soil contamination. We present a discussion of the advantages and limitations of different soil contamination assessment methods. In this study, we analyzed seven trace elements (As, Cd, Cr, Cu, Hg, Pb, and Zn) that are indicators of soil contamination in Dexing, a city in China that is famous for its vast nonferrous mineral resource...

Sulak alan ekosistemleri çok sayıda fauna ve flora türüne yaşam ortamı sunan, aynı zamanda insanların faydalandığı önemli doğal kaynak değerleridir. Son yıllarda artan antropojenik etkiler sulak alanlarda PTE kaynaklı ekolojik bozulmaya buralardan çeşitli yollarla faydalanan insanlar üzerinde sağlık risklerine neden olmaktadır. Bu nedenle, bozulma riski analizleri yapmak için analitik metotlar ...

Heavy metal pollution significantly reduces the quality of environment and threatens human health, especially in industrial cities. This study investigated toxic metals concentrations, levels health risks assessment urban soils Yazd City, as an city center Iran. Soil surface samples (0–10 cm) were collected from 30 points area for geochemical analysis. The concentrations heavy determined using ...

In this study, concentrations of heavy metals in soils around a Zn-smelter in Qeshm island, Iran, are investigated. Calculated geoaccumulation index (Igeo), contamination factor (Cf), and contamination degree (Cdeg) values indicate surface soil contamination by toxic metals (As, Cd, Pb, and Zn). The results also indicate that most contaminated areas are located in the vicinity of the smelter an...

This paper provides an overview of different methods assessing the trace metal (TM) contamination status sediments affected by anthropogenic interference. The geochemical background determination are also described. A total 25 papers covering rivers, lakes, and retention tanks in areas subjected to pressure from last three years (2019, 2020, 2021) were analysed support our examination assessmen...

introduction we can obtain useful information about aquatic systems by studying heavy metals in surface sediments. marine sediments can bring out the aquatic contamination. due to heavy metal toxicity, hard biodegradation and easy bioaccumulation in aquatic ecosystems, various indices have been developed such as sediment quality guidelines (sqgs), enrichment factor (ef), pollution load index (i...

Abstract The paper presents the results of research into toxic metal concentrations in surface layer bottom sediments Lake Gopło. objectives were to identify levels and spatial variability Cu, Pb, Cd, Zn, Ni, Cr, As Hg concentrations, their potential sources determinants pollution levels. Metal contamination was assessed using geoaccumulation index (Igeo), load (PLI) ecological risk (RI). Chemo...

Heavy metal(loid)s (HMs) contamination in agricultural soil and crops is related to the quality safety of products public health has attracted worldwide attention. This study systematically investigated bioaccumulation HMs including Cd, Pb, Cr, Hg, As Se associated (Tea, Plum Corn) Guizhou Province, China, assessed risks edible part using bioconcentration factor (BCF), geoaccumulation index (Ig...
