The present study seeks to both estimate and analyze the rate of heavy metal changes in soils road margins affected by traffic on Fasa-Darab Road, Iran. Muller index, contamination factor (CF), Geoaccumulation index (Igeo), potential ecological risk (PERI), pollution load (PLI) were calculated determine rate. Principal component analysis was also employed most relevant parameters affecting PERI...

In this study, the concentrations of heavy metals (Ca, Zn, Cu, Fe, Mn, Ni) in thesediment of Shavoor River in Khuzestan Province in Iran has been investigated. After the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the geochemical phases of metals in sediment samples the 5-ste...

The Kolleru Lake is a famous Ramsar wetland of international significance. In this study heavy metal contents in water and sediment samples are reported. It is found that certain potentially toxic metal ions like chromium (4.5-80 µg/L), copper (1-20 µg/L), manganese (1-313 µg/L) and zinc (1.2-57 µg/L) are present in variable quantities in the lake water. When normalized with respect to concentr...

Irrigation food crops are intensively cultivated on/or around the abandoned tin mine areas in Plateau State, Nigeria. Vegetables on contaminated soil a potential risk to human health, particularly, through consumption. The physico-chemical properties of and sediment revealed that soil/sediment were acidic, non- saline low fertility. Most heavy metals’ concentrations agricultural soils above DPR...

A study has been conducted to evaluate the degree of Heavy Metals (HM)contamination on farm soils Wakwa’s, using enrichment factor (EF), geo-accumulation index (Igeo), pollution load (PLI), Ecological risk factors (Eir), indices(PER) and statistical analysis.In currentstudy, composite surface agricultural soil samples were collected in 4 sites analyzed for concentration HMs including As, Ba, Co...

This study reports the presence of heavy metals (Cr, Ni, Cu, Cd, Pb) in sediment and water column Köyceğiz Lagoon Estuary System (KLES) (South-West Anatolia). The mean metal concentrations (µg L-1) were found as Cr: 3.72-8.36, Ni: 6.51-9.48, Cu: 1.29-11.88, Cd: ND-0.08, Pb: ND-0.34. samples to be below internationally acceptable limits. (mg kg-1) 1.75-4.25, 5.24-12.69, 0.25-0.51, <0.01, ...

The spatial and temporal distributions, contamination evaluation, source apportionment of Cu, Zn, As, Pb, Cd, Cr in the sediments Hulun Lake were explored this work. pollution characteristics six heavy metals assessed by single factor index (PI) geo-accumulation (Igeo). sources surface analyzed positive definite matrix factorization (PMF) Pearson correlation analysis. sedimentary records core r...
