This study evaluated the concentration of toxic elements in soil samples from agricultural fields districts Sachaca, Socabaya, Hunter, Quequeña, Yarabamba, Characato and Tiabaya city Arequipa, Peru. The ecological risk, enrichment factor (EF), geo-accumulation index (Igeo) integrated risk (RI) were estimated, while health was determined with hazard coefficient (HQ) (HI) values. Seven collected ...

This research (1) analyzed the content of Pb and Cd in water sediment; (2) physical chemical parameters water; (3) determined enrichment factor accumulation index sediments; (4) to identified quality based on Pollution Index (IP) STORET. The analysis was carried out using PCA (Principal Component Analysis) Pearson's correlation, conducted downstream section Musi River, Palembang, a random sampl...

The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

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...

Heavy metals in road dust pose a significant threat to human health. This study investigated the concentrations, patterns, and sources of eight hazardous heavy (Cr, Ni, Cu, Zn, As, Cd, Pb, Hg) street Zhengzhou city PR China. Fifty-eight samples were analyzed based on three methods risk assessment, i.e., Geo-Accumulation Index (Igeo), Potential Ecological Risk Assessment (RI), Nemerow Synthetic ...
