AbstractA new solid — phase extraction sorbent was developed based on stepwise anchoring of two ligand molecules for the determination of copper, zinc, lead and cadmium in drinking water by flame AAS. Amberlite XAD-2 functionalized with 4′-(2-hydroxyphenylazo)-3′-methyl-1′-phenyl-2′-pyrazolin-5′-one (HPAPyr) was utilized for preconcentration/separation of these elements. The sorbent was prepared by two successive azo coupling reactions. First, 2-aminophenol was anchored to the amino groups in the resin resulted from nitration followed by reduction. Then, the resulted 2-aminophenol functionalized resin was further diazotized and coupled to the pyrazolone compound and the final product HPAPyr-XAD-2 was characterized by IR and elemental analysis. The optimum pH range for sorption, shaking time, exchange capacity, sample flow rate, preconcentration factor and interference from co-existing ions were investigated. All metal ions were quantitatively desorbed from the resin by 4.5 mol L−1 nitric acid solution. The sorbent provides limit of detection within the range 0.9–3.3 µg L−1 and concentration factor up to 250. The procedure was validated by analysis of certified material NIST-SRM 1577b. Application to drinking water showed satisfactory results with relative standard deviation RSD ≤ 8.5%.

Seven elements, namely, arsenic, lead, cadmium, copper, zinc, iron and manganese were determined in 31 samples of Serbian plum brandies by applying atomic spectrometry techniques. Flame atomic absorption spectrometry was used for quantification of copper, iron, zinc, manganese, lead and cadmium; and hydride generation atomic spectrometry absorption for arsenic quantification. Measured concentrations of heavy metals and arsenic was assessed according to the Serbian regulations, official regulations of some other countries and in respect of microelements content in other similar distilled alcoholic beverages. Amounts of microelements in maximal recommended daily and weekly intake of plum brandy were determined. The influence of production (home made and industrial), type of wooden barrel (oak and mulberry), and duration of ageing process on the content of Zn, Cu, Fe and Mn in plum brandies, as well as coefficient of correlation between Cu content and pH value were also studied.

Under the conditions of a lysimetric experiment on podzolic chernozem, it was found that the use of dolomite flour contributed to a decrease in the mobility of metals and their translocation into crop products, which was reflected in a decrease in their removal relative to the background. The use of mineral fertilizers by increasing the yield of phytomass contributed to an increase in the removal of copper, zinc, lead and cadmium from the soil. The largest total removal of copper, zinc, lead and cadmium with the phytomass of annual grasses (8,035 mg/m2) is observed when using a mineral fertilizer system, and the smallest removal of the indicated metals is observed when using lime without manure (5,092 mg/m2).

The results of a field lysimetric experiment on podzolized сhernozem to study the coefficients of biological absorption of heavy metals and trace elements for root crops and tops of fodder beets using various systems of mineral fertilizers are presented. Analysis of the empirical series of accumulation of elements in the main and byproducts of fodder beet plants showed that the level of accumulation of zinc, lead and cadmium in root crops is significantly lower than in the tops, and the copper content is relatively evenly distributed between the main and by-products according to the variants of the experiment. In the variant with an increased agrochemical background, there was a decrease in the content of copper, zinc and lead in the main and by-products of feed beets, which may be due to the effect of biological dilution when using mineral fertilizers.

Blood clam, Tegillarca granosa, facing increasing danger of heavy metal contamination. In order to investigate the toxicological effect of copper (Cu), zinc (Zn), lead (Pb), and cadmium (Cd) on T. granosa, histopathological alternations were investigated in present study. Based on histopathological observation, Cu, Pb and Cd showed different degrees of damages to gills range from gill degeneration, gill fusion to interlamellar space and cilia reduction. In general, the more toxic the more severe damages to gills were observed. Massive oocytes degeneration in female gonad, muscle fiber degeneration and increased gap between muscle fibers in foot were found in Cd-exposure-treated T. granosa. Zn exposure induced an increase of epidermis wrinkles and a reduction of inner gaps. The results reveal different toxic mechanisms of tested heavy metals on T. granosa.

In this article the histological structure of gills and kidneys of the Prussian carp is considered and researched. The research was conducted in the waters of the Zaporizhian (Dnipro) reservoir, namely in the Samara Bay and the lower part of the reservoir (near the village of Viiskove) during 2017–2019. Previous studies have revealed the excess of maximum permissible concentrations of heavy metals in the water of the Samara Bay compared to the lower part of the Zaporozhian reservoir. High levels of nickel and cadmium were observed in the Samara Bay. Statistically significant differences were found between the content of copper, zinc, nickel, lead and cadmium in the two areas of the reservoir (p

Heavy Metal Waste

High amount of heavy metal waste produced from the industrial activities has become an important global issue for several decades due to its hazardous effect on the human and environment. Since heavy metal is highly toxic and cannot be eliminated easily, the application to reuse the heavy metal waste without harming the environment must be investigated thoroughly. This paper reviews the incorporation of heavy metal into clay precursors as a good potential for the reduction of environmental pollution. The results from the previous studies show the transformation of heavy metal such as copper, zinc, lead and cadmium into less hazardous species when incorporating into clay precursors. These transformations have reduced the mobility of heavy metal as a crystalline structure is formed after the thermal treatment. It is found that the immobilization process successfully stabilizing heavy metal and increases the metal’s resistance against the acidic attack through the formation of low permeable structure in the clay precursors. Hence, the incorporation of heavy metal into clay precursors is proven to be a great prospect in reducing environmental pollution.
