In 2007, it was shown that the shipping of lead (Pb) through Esperance Port in Western Australia resulted in contamination and increased Pb concentrations in children. A clean-up strategy was implemented; however, little attention was given to other metals. In consultation with the community, a cross-sectional exposure study was designed. Thirty-nine children aged 1 to 12 years provided samples...

The problem of impurities and defect states in lead telluride-based semiconductors is of crucial importance for their practical applications. X-ray absorption fine structure (XAFS) techniques are capable to address some of the key issues regarding impurities position, their valent state, as well as the local structural changes of the host lattice in the immediate surrounding of the impurity ato...

The uptake and distribution of selected heavy metals were followed and related to cytotoxicity using various parameters of proliferation and viability of cultured cells. The effects of short-term lead exposure on DNA synthesis were reversible, indicating that lead does not significantly influence genetic cellular function. In contrast, nickel effects persisted, indicating that DNA is one of the...

AIM To determine differences in metal and metalloid exposure between residents of areas in eastern Croatia exposed to heavy fighting during the war in Croatia and residents of areas exposed to moderate fighting. METHODS Concentrations of aluminum (Al), arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), lead (Pb), uranium (U), vanadium (V), and zinc (Z...

The contamination of groundwater by heavy metal ions around a lead and zinc plant has been studied. As a case study groundwater contamination in Bonab Industrial Estate (Zanjan-Iran) for iron, cobalt, nickel, copper, zinc, cadmium and lead content was investigated using differential pulse polarography (DPP). Although, cobalt, copper and zinc were found correspondingly in 47.8%, 100.0%, and 100....

In order to acquire the pollution feature and regularities of distribution of metals in the topsoil within the sixth ring road in Beijing, a total of 46 soil samples were collected, and the concentrations of twelve elements (Nickel, Ni, Lithium, Li, Vanadium, V, Cobalt, Co, Barium, Ba, Strontium, Sr, Chrome, Cr, Molybdenum, Mo, Copper, Cu, Cadmium, Cd, Zinc, Zn, Lead, Pb) were analyzed. Geostat...

fifty-four drinking groundwater samples were collected in april 2010 from some districts of the dakahlyia governorate, egypt. the water samples were analyzed by atomic absorption spectrophotometer for iron, manganese, lead, nickel, chromium, zinc, copper, cobalt and cadmium concentrations. all samples but two were found suitable for drinking; from the water sample from aga district showed sligh...

The accumulation of lead (Pb), cadmium (Cd), nickel (Ni), iron (Fe), copper (Cu), and zinc (Zn) in the femora of four rodent species (Apodemus flavicollis, Apodemus sylvaticus, Myodes glareolus, and Microtus arvalis) trapped at different polluted areas in Slovakia (Kolíňany and Nováky) was investigated in the present study. We detected the highest concentration of Pb in bones of A. sylvaticus f...

Magnetoelectric (ME) composites that simultaneously exhibit ferroelectricity and ferromagnetism have recently gained significant attention as evident by the increasing number of publications. These research activities are direct results of the fact that multiferroic magnetoelectrics offer significant technological promise for multiple devices. Appropriate choice of phases with co-firing capabil...
