In the research described in this paper, studied was sorption capacity of natural and ferric modification of zeolite tuff containing mineral clinoptilolite from the Nižný Hrabovec deposit to remove potentially toxic metals (ionic forms of chromium, nickel, copper and aluminium) from their water solutions. We reported that the Fe (III) zeolite has an enhanced ability to sorption of Cu (II), and ...

The adsorption technique using chemically treated powder of bark of Acacia arabica was applied for the removal of toxic heavy metals from polluted waste water. The extent of adsorption found to be dependent on the pH and the time of contact. The adsorbent is effective for the quantitative removal of various toxic metals from the contaminated aqueous sample. The method is quite feasible, economi...

BACKGROUND Although breastfeeding of infants is recommended globally, the fact that maternal toxic metal stores are mobilised into breast milk implies infants, whose mothers live and work in mining communities, are at risk of multiple exposure to mining related toxic metals, such as Lead (Pb), Mercury (Hg), Cadmium (Cd) and Arsenic (As), through breast milk intake, in addition to in utero expos...

Bakhtegan–TashkLakes (BTL) and Kamjan Marsh, one of the Ramsar sites with an area 1323 km 2 , have been shrunk due to groundwater overexploitation, construction two new dams drought. Evaporation BTL water significantly increased potentially toxic metal (PTMs) average total dissolved solids (TDS) from 45000 382000 mg/l. This study focuses on contamination sources 16 PTMs. The sampling include 24...

The reduced availability of water resources in Egypt has imposed the need to intensify use wastewater for crop irrigation alluvial soils. Relevant effects can derive from contents potentially toxic metals (PTMs) supply soils, crops, and groundwater these areas. For this reason PTM content be monitored evaluate minimize health hazards. Therefore, context, two areas SE Nile Delta subjected 25 yea...

The study aims at investigating chemical speciation, bioavailability and risk assessment of some selected metals in soils around refined petroleum depot using the concentrations as variables to ascertain impacts activities within depot. Surface-soils (0–15 cm) were collected from premises Pipelines Product Marketing Company, Ibadan, Nigeria, while control samples 200 m away location. Electrical...
