Accumulation of Cd, Pb, Zn, Cu (HM) by spring barley (Hordeum vulgare L.) from sod podzolic sandy loam and chernozem soils, impacted by heavy metals pollution in the soils, is studied in the article. The aim of study has been to determine spring barley bioaccumulation capacity impacted by the HM pollution with the high level of Cd, Pb, Zn, Cu concentration in soils. The HM concentration diapason caused...
In vitro coffee seedlings were exposed to an electromagnetic field (EMF) of 2 mT during 3 minutes in establishment, multiplication, and acclimazation phases. Shoot and root lengths and leaf pair numbers of treated groups increased when compared to control; in addition to SOD, CAT, and APX activities of in vitro-treated groups showed a decrease in levels. Four months after the magnetic treatment was...
Contamination of soils around mines by heavy metals has not yet received the serious attention that it deserves in South Africa. The current study evaluated the concentrations and levels of pollution by trace metals in soils around a Ferro-chromium mine in South Africa. Soil samples were collected from 20 locations in four different directions, namely southwest, southeast, northwest, and northeast...
The use of animal waste for soil amendment is a viable option for waste management. For safe and sustainable management of waste, it is important to assess its chemical speciations. Therefore, an experiment was carried out to compare changes in heavy metals (HM) [cadmium (Cd), mercury (Hg), nickel (Ni), and lead (Pb)] fractions in five types of livestock manures, namely cow, goat, sheep, chicken,...
This study measured levels of cadmium, chromium, copper, nickel, lead, and zinc in fruits of Capsicum annuum L., Phaseolus vulgaris L., and Solanum melongena L. during the 2007 vegetation period, to determine levels of metal pollution in Istanbul Province. Plant and soil samples were collected from six sites in Istanbul (Brook Coast area, inner city, industrial area, suburban, roadside, and rural...
Electronic waste (e-waste) has become a subject of growing environmental concern in developing countries due to legal/illegal import of electronics from developed nations. In this study, concentrations of heavy metals in and around the largest e-waste dumping site in Nigeria, Alaba International Market in Lagos, was investigated. Concentrations of five heavy metals, namely: cadmium (Cd), chromium...
In order to immobilize heavy metals, sorbents that meet the following three criteria can be used: 1) they are non-toxic 2) they cannot make the physicochemical properties of soil worse, and even improve them 3) they have an immobilizing and specific impact on heavy metals. This study compares the influence of mineral and organic sorbents, as well as the presence of selenates (VI), on limiting lead...
We have investigated trace metal accumulation in sediment and in insect larvae in a small lowland river, which is an ecosystem with a large load of organic allochthonous matter (leaf packs) due to its first stream order section running across forest as well as along the edge of a large city (anthropogenic enrichment). Two study sites of this reach are separated by recreation ponds. Mean annual discharge...
Aggregated amyloid peptides (AP), major components of senile plaques, have been considered to play a very important and crucial role in the development and neuro-pathogenesis of Alzheimer’s disease (AD). In the present in vitro, study the synergistic effects of Pb2+, a heavy metal, and AP on the human neuroblastoma SH-SY5Y cells were investigated. The cells treated with Pb2+ (0.01–10 μM) alone exhibited...
The Legnica-Głogow Copper Mining District has been the site of metal mining for more than 50 years. Intensive environmental actions have, more recently, been aimed at reducing emissions of harmful substances in the region. We compared the blood lead concentrations of children resident in the copper smelting district in southwestern Poland in 1995 and 2007. The sample included 1,405 children, 7-15...
Deposition rates of atmospheric particles were determined using previously published ²¹⁰Pb data in soils and air. The dry deposition velocities for moorland and woodland soils were 2.2±1.8 and 9±2 mm・s⁻¹, respectively. The ²¹⁰Pb concentration in rain was calculated to be 94±10 mBq・L⁻¹. The large (~4 times) deposition velocities in woodland relative to moorland soils is an indication of the degree...
The influence of L-arginine and Nω-nitro-L-arginine (L-NNA) on lead-induced oxidative stress in kidneys of rats with different resistance to hypoxia was studied. The animals were exposed to lead nitrate (3.6 mg/kg, daily) for 30 d and treated with L- arginine (600 mg/kg) or L-NNA (35 mg/kg) 30 min before each injection of lead nitrate. Lead exposure led to a significant increase in the level of thiobarbituric...
