This study aims to investigate the groundwater vulnerability concerning potentially toxic elements in vicinity of abandoned iron mine Ouixane (Morocco). A modified DRASTIC method (DRSTI) is proposed with satisfactory results. High zones represent 40% area, while medium and low represent, respectively, 42% 18% area. These results have been validated by geochemical analyses carried out framework ...

Biologically available phosphorus supports plant growth but can also cause environmental contamination. Sequential extraction methods, such as Hedley fractionation, are the most widely used to assess from solids. However, methods exhibit numerous deficiencies. The USEPA Leaching Environmental Assessment Framework (LEAF) is a tiered system developed evaluate releases of Potentially Toxic Element...

In the present study, quality of surface water from five different locations on banks river Sutlej in Ropar wetland was determined by estimation physico-chemical parameters; indices; contents arsenic, cadmium, cobalt, chromium, copper, iron, manganese, lead and zinc; determination genotoxic potential samples using Allium cepa root chromosomal aberration assay plasmid pBR322 DNA nicking assay; a...

Large rivers and especially their deltaic parts adjacent coastal zones are subjected to strong anthropogenic influence often considered as hotspots of environmental pollution. The Don River is one the largest most important in South Russia. basin a highly urbanized area with developed agriculture industry which negatively affect water quality, aquatic ecosystems soils. main objectives proposed ...

Fly ash from Mae Moh power plant in Lampang province, northern Thailand (unit 6, 8, 10 and 11) was investigated to find out the heavy metals (As, Cd, Hg, Pb Zn) content of fly ash. Every metal except mercury is at higher level than background soil. The average arsenic two times soil unit 11 contains largest amount (148.5 mg kg-1). Mercury dumping site not detectable. Sludge, end product wastewa...

Effective environmental management and contamination remediation require accurate spatial distributions predictions of potentially toxic elements (PTEs) in the soil. However, no single method has been developed to predict soil PTE accurately. This study evaluated advanced geostatistical empirical Bayesian kriging regression prediction (EBKRP), machine learning algorithm random forest (RF), hybr...

The accumulation of potentially toxic elements (PTE) in a soil–rice system poses significant issue concern agricultural soils, particularly the polluted or high PTE geological background regions, such as karst areas. source identification, bioaccumulation factors PTE, and its health risk were investigated by correlation analysis, principal components single/comprehensive assessments soil-rice M...

High levels of potentially toxic elements (PTEs) in water bodies negatively affect the biota aquatic ecosystems and surrounding environments. A risk assessment investigation distribution PTEs seawater Jazan coastal area, southwest Saudi Arabia, was conducted. Thirty-two surface samples were collected, contamination (Cd) heavy metal pollution (HPI) indices, as well multivariate statistics, appli...
