Radiochemical and elemental analysis of clay soils collected from different locations within Ekiti State have been performed in this study using gamma and XRF spectrometric measurements. The results of this study show that the mean concentrations of uranium ranged from 2.2 ± 1.0 mg/kg to 3.2 ± 1.1 mg/kg, that of thorium ranged from 4.0 ± 0.5 mg/kg to 5.7 ± 1.7 mg/kg, while potasium presented in...

We assessed the spatial and temporal variations of pollution indicators and geochemical and trace metal parameters (23 in total) from water and sediment (144 samples) of three different eco-niches (beach, fishing harbor, and estuary) in larger coastal cities of southern India (Cuddalore and Pondicherry) for one year. A total of 120 marine Pseudomonas isolates were challenged against different c...

Bogra city is highly susceptible to environmental pollution due to over population, rapid industrialization and urbanization during the last decades. A study was conducted to determine heavy metals (Cu, Zn, Pb, Cr, Cd and Ni) pollution level and physicochemical properties in the soils of Bogra city. The concentrations of heavy metals in 14 soil samples were determined by using an Atomic Absorpt...

Coastal environmental assessment techniques have evolved into one of the most important fields for long-term development and management coastal zones. So, overall aim present investigation was to provide effective approaches making informed decisions about Gamasa coast sediment quality. Over a two-year investigation, samples were meticulously collected from estuary littoral shelf. The inductive...

the chemical speciation of heavy metals (arsenic, chromium, copper, lead, zinc and tin) in the sediments offormer tin mining catchment bestari jaya, peninsular malaysia was determined by using the latest version of the community bureau of reference, usually called the bcr 3-step sequential extraction procedure. furthermore, a fourth step was introduced for digestion and analysis of the residue....

accumulation of trace metals in sediment can cause severe ecological impacts. the present study determines the elemental concentrations and chemical partitioning of heavy metals in surface sediment of shadegan wetland. shadegan wetland is one of the most important wetlands in southwest of iran and it is in ramsar-listed wetlands. for this purpose, 7 sampling stations were selected for sediment ...

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...

The alteration of hydrologic condition of Three Gorges Reservoir (TGR) after impoundment has caused numerous environmental changes. This study investigated the distribution, accumulation and potential sources of the seldom monitored trace elements (SMTEs) in sediments from three tributaries (ZY, MX and CT) and one mainstream (CJ) in TGR during different seasons. The average contents of most SMT...
