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...
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,...
Cadmium is a toxic heavy metal which can cause numerous alterations in cell functioning. Exposure to cadmium leads to generation of reactive oxygen species, disorders in membrane structure and functioning, inhibition of respiration, disturbances in ion homeostasis, perturbations in cell division, and initiation of apoptosis and necrosis. This heavy metal is considered a carcinogen by the Agency for...
We observed the effect of cadmium (Cd group) and cadmium+zinc (Cd/Zn group) in the liver of turkeys after a 71-day exposure. The experimental birds were divided to three groups; control group (Control), group exposed to cadmium (group Cd) as CdCl₂ (aqueous solution, 0.5 mg/kg feed); and group Cd/Zn exposed to the same dose of cadmium as Cd group plus zinc as ZnSO₄ (aqueous solution, 90 mg/kg feed)...
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...
To investigate the biological activities of anthocyanins, which are induced by cadmium in A. imbricata, the antioxidant properties of anthocyanins were investigated using various antioxidant assays, namely 1,1 -diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azinobis-(3-ethylbenzthiazoline-6- sulfonic acid) (ABTS) radical scavenging activity, reducing power, and β-carotene bleaching...
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...
In this paper, an attempt is made to characterize PM₁₀ imission field in the area of Warszawa with regard to PM content of the metals As, Cd, and Ni. Particulate matter concentration measurements were performed within this agglomeration with the use of many measuring methods, different not only in respect of the sampler operation rules, but also of the accuracy, sampling frequency, and separation...
