The Effect of Liming and Sewage Sludge Application on Heavy Metal Speciation in Soil

matter and nutrients (Unsal and Ok 2001; Speir et al. 2003; Jouraiphy et al. 2005). The total amount of heavy metals in the sludge is not enough to assess their toxicity; another factor is their * Elżbieta ...

The effects of soil liming and sewage sludge application on dynamics of copper fractions and total copper concentration

The paper deals with effects of liming and different doses of municipal sewage sludge (5, 10, and 15 % of soil mass) on copper speciation in soil. In all samples, pH was determined together with total copper concentration, which was measured with the ICP-AES method. Concentration of copper chemical fractions was determined using the seven-step procedure of Zeien and Brümmer. In...

Copper and zinc concentrations of medicinal herbs and soil surrounding ponds on agricultural land

This study measured copper and zinc concentrations in medicinal herbs and soil sampled from three agricultural fields with ponds from mid-June till the end of July 2014. Six herb species were tested: Potentilla anserina L., Mentha arvensis, Achillea millefolium L., Comarum palustre L., Lysimachia vulgaris L., and Lycopus europaeus L. Two of the ponds were in the borough of Jab...

Pesticide residues in some herbs growing in agricultural areas in Poland

The aim of this paper was to assess residue content of plant protection products in selected herbs: Achillea millefolium L., Cichorium intybus L., Equisetum arvense L., Polygonum persicaria L., Plantago lanceolata L., and Plantago major L. The study comprises herbs growing in their natural habitat, 1 and 10 m away from crop fields. The herbs, 30 plants of each species, were...

Pesticide residues in cereal crop grains in Poland in 2013

This paper presents the results of the audit on pesticide residues in cereal grains throughout Poland in 2013. The number of all samples of cereal grains was 380. Altogether 292 active substances of plant protection products were checked in the audit. Qualitative and quantative analyses were done according to Polish Standard PN-EN 15562:2008, using the LC-MS/MS technique. The...

Content of Zinc and Copper in Selected Plants Growing Along a Motorway

In 2011 a study was carried out analyzing the effects of road traffic on bioaccumulation of zinc and copper in selected species of dicotyledonous plants growing on adjacent grasslands. To do the research the plants were sampled from the 9-km-long Siedlce bypass, a part of the international route E-30. They were collected during the flowering stage, at following distances from the...

Electrochemical uranyl biosensor with DNA oligonucleotides as receptor layer

The feasibility of using gold electrodes modified with short-chain ssDNA oligonucleotides for determination of uranyl cation is examined. Interaction between UO 2 2+ and proposed recognition layer was studied by means of voltammetric and quartz crystal microbalance measurements. It was postulated that ssDNA recognition layer functions via strong binding of UO 2 2+ to phosphate...
