At present, heavy metals are generally recognized as priority soil pollutants, while the most active pollutants are their mobile forms, which can pass from solid phases into soil solutions and be absorbed by plants. It is known that the vegetative mass of agricultural crops is capable of accumulating large amounts of heavy metals. Ornamental flower crops, which firmly occupy their ecological niche, are practically not considered from this point of view. The aim of this work was to study the features of the accumulation of heavy metals in the aboveground and underground organs of some representatives of the genus Paeonia L. in the urbanized environment of the city of Ufa. The objects of research were four species ( P. peregrina Mill., P. lactiflora Pall., P. lactiflora f. rosea, P. delavayi Franch.) (Family Paeoniaceae Rudolphi) and three varieties of hybrid peony (Appassionata, Mustai Karim, Jeanne dArc). The study of the elemental composition of the aboveground and underground parts was carried out according to the method Determination of As, Pb, Cd, Sn, Cr, Cu, Fe, Mn and Ni in samples of food products and food raw materials by the atomic absorption method with electrothermal atomization. Mathematical data processing was carried out using generally accepted methods of variation statistics using the AgCStat software package in the form of an Excel add-in. Eight element studies are presented for each raw material group. Quantitative indicators of elements are given in mmol/kg of air-dry raw materials. It was revealed that in the studied samples the copper content was 4.152520.00 times higher than that of other elements. The minimum concentrations of arsenic (0.00350.0064 mmol/kg), chromium (0.00190.0046 mmol/ kg), manganese (0.01740.0219 mmol/ kg) and iron (0.00590.0125 mmol/ kg) were noted in the roots; lead (0.0030.037 mmol/kg), cadmium (0.00020.001 mmol/kg) and copper (0.14770.2134 mmol/kg) - in the leaves; nickel (0.00820.0179 mmol/kg) - in the flowers of the studied paeonies. The maximum content of arsenic (0.00620.0123 mmol/kg) and chromium (0.00280.0063 mmol/kg) was found in the leaves; lead (0.00270.0223 mmol/kg), nickel (0.01670.0209 mmol/kg), manganese (0.01730.0212 mmol/kg) and iron (0.00870.0138 mmol/kg) - in stems; cadmium (0.00020.0009 mmol/kg) and copper (0.1440.244 mmol/kg) - in flowers. Therefore, cutting paeonies in the autumn before retirement avoids the accumulation of these microelements in the soil. The results of the correlation analysis showed that the absolute values of the concentrations of the studied elements in the considered taxon of paeonies correlate with each other to a moderate and strong degree.

 El objetivo de este estudio fue determinar los niveles de acumulación de metales pesados como el cadmio (Cd) y el plomo (Pb) derivados de actividades antropogénicas, como los humos metálicos de la soldadura y el tráfico de vehículos, en la pulpa de guayaba (Psidium guajava) en la ciudad de Cartagena. -Bolívar. Las muestras se dividieron en tres (3) grupos según la proximidad de las fuentes de contaminación. En el grupo 1, menos de 100 m de industrias metalúrgicas, las concentraciones de Cd en el rango de 0.0400 ± 0.33 mg / Kg y 0.0483 ± 0.15 mg / Kg, mientras que los valores de Pb oscilaron entre 0.036 ± 0.22 mg / kg y 0.060 ± 0.01 mg / kg . Para el grupo 2, se tomaron muestras en 3 lugares donde no se identificó claramente ninguna fuente de contaminación, lo que resultó en concentraciones de Cd 0.0215 ± 0.05 mg / Kg y 0.0260 ± 0.10 mg / Kg, mientras que para el Pb solo se encontró en una de las muestras cuyo valor fue 0.035 ± 0.15 mg / Kg. Finalmente, para el grupo 3, se tomaron muestras en 2 ubicaciones ubicadas a menos de 100 m de avenidas de alto tráfico, resultando en valores muy similares para Cd (0.0220 ± 0.13 mg / Kg y 0.0311 ± 0. 22 mg / Kg), mientras que para Pb el los valores fueron muy precisos (0.032 ± 0.35 mg / Kg y 0.029 ± 0.20 mg / Kg). Estas mediciones muestran cómo, en sitios cercanos a las actividades humanas, las concentraciones de estos metales pesados están en niveles más altos, lo que representa un peligro para su consumo debido a la bioacumulación en diferentes tejidos humanos.Palabras clave: metales pesados, humo metálico, contaminación, tráfico vehicular.

Contamination Of Soils

A significant degree of ploughness of agricultural lands of Ukraine has led to increased erosion and the creation of soils of varying degrees of washout, which leads to dehumification and contamination of soils with toxic substances. Therefore, the purpose of the study was to establish the features of horizontal migration and accumulation of heavy metals of lead, cadmium, copper, and zinc, trace elements of boron and manganese, radionuclides of caesium and strontium on podzolic heavy loamy chernozems with varying degrees of washout: non-eroded, weak and medium washout, conditioned by the development of erosion processes. During the study, spectrophotometric, colorimetric, gamma-spectrometric, and radiochemical methods were used to determine the content of toxic substances in the soil. The study results showed that on slightly washed soils, the content of humus is 12.9% less, easily hydrolysed nitrogen – 13.3%, mobile forms of phosphorus – 51.1%, mobile potassium – 34.9% less than on slightly washed soils. The humus content on medium-washed soil was 8.8% less than on lightly washed soil, easily hydrolysed nitrogen – 14.3% less, mobile phosphorus – 15.3% more, mobile potassium – 42.9% more. A strong horizontal migration of mobile lead forms in washed podzolic heavy loamy chernozem was established, which increases with increasing degree of soil washout with the content of mobile lead forms on medium-washed soil by 24% more than on non-eroded soil. The same dependence was established on the content of mobile forms of zinc in the soil, with their predominance on medium-washed soil by 17 %, compared to non-washed. The content of mobile forms of copper is lower on slightly washed soil, compared to non – washed soil by 5%, boron – 18.8% less on non-washed soil, compared to medium-washed, and the content of mobile forms of manganese increases by 3.3% from slightly to medium-washed soil. It was also found that the concentration of caesium decreased by 25.6% on medium-washed soils, compared to non-washed ones
