Specificity of heavy metals distribution in atropa belladonna plants

Aim. To investigate the content of heavy metals (HM) in the seeds and roots of Atropa belladonna plants. To identify possible changes in their concentrations over the years of growing these plants. Methods. Field and spectrometric method, methods, common for agriculture, plant growing and statistics. Results. The content of heavy metals (HM) in the seeds and roots of belladonna plants was determined. It was found that plant roots ac- cumulate them much more compared to the seeds. The concentration of such HM as barium, cadmium, copper, iron, manganese, nickel, potassium, sodium, strontium, and zinc in the plants exceeds the maximum permis- sible level, which testifi es to partial soil contamination in the region. Conclusions. As there are no data about maximum permissible ratios for the content of important chemical elements in the raw plant material, specifi ed in normative and regulatory documents, scientists have to launch complex investigations, involving specialists of relevant fi elds to identify the mentioned gradation. It was determined that the main part of HM is accumu- lated in the roots of belladonna plants, whereas their content in the seeds is several times smaller or equals the value under the sensitivity threshold of analytical devices. This fact testifi es to the prospects of growing the mentioned medicinal herb in Kyiv region for further industrial processing. Chemical elements, which belong to compounds of lanthanides and actinides, are almost not accumulated in belladonna plants.

Aim. To investigate the content of heavy metals in the seeds of milk thistle (Silybum marianum (L.) Gaertn.) and in the product of its processing – oil. To reveal possible changes in the concentration of heavy metals in the years of cultivating this plant. Methods. The fi eld and spectrometric methods were applied; the results were processed using the technologies, common for agriculture, plant production and statistics. Results. The content of heavy metals in the seeds of milk thistle was defi ned. It was determined that their concentration exceeds maximal acceptable coeffi cient for the medicinal plant material. It was established that in 2013 the seeds of milk thistle accumulated several times more Ba, Ca, Fe, Mg, Mo, Sr, V compared to the indices of 2014, while Al, Co, Ag were found only in the samples of the seeds, harvested in 2013. Conclusions. As the regulatory documents regarding many relevant elements, which belong to heavy metals, do not specify maximal accept- able coeffi cients for the content of the latter in the medicinal plant material, it is reasonable to conduct complex studies, involving the specialists of relevant fi elds, in order to stipulate this gradation. In the Kyiv region the milk thistle plants accumulate a large amount of such heavy metals as cadmium, manganese, strontium, and zinc, which exceeds maximal acceptable degrees of accumulation and testifi es to partial pollution of region soils. It was established that the concentration of the main part of heavy metals in the product of processing milk thistle – oil – is decreased to the value under the threshold of analytic devices. This fact proves the pros- pects of growing milk thistle for industrial processing purposes.

St John's wort is one of the best known and used medicinal plants. The demands for St John's wort in Serbia is still supplied by the collection of native plants. Therefore it was necessary to examine the concentration of heavy metals in the soil and in plant material on serpentinites and to assess the potential safe harvesting and further utilisation of this plant species. The research was performed on three serpentinite sites in Serbia: Zlatibor, Divcibare and Goc. The main soil types were determined and the contents of 7 chemical elements were analyzed in the soil and in the plant material. It was determined that the soils of all three localities had increased concentrations of nickel, chromium and manganese. The St John's wort plant material (leaves) showed the increased concentrations of iron, nickel and chromium. It was concluded that St John's wort was a tolerant species regarding the heavy metal content, and it was recommended to avoid its harvesting on the investigated localities.

Introduction. Intensive exploration and processing of mineral raw materials in the Trans-Baikal territory has caused the accumulation of considerable amount of industrial mining waste with high content of chemical elements of different classes of hazard. Currently 33 tailings storage facilities (TSF) accumulating approximately 3 milliard tons of different industrial waste are located in the territory of the region. The aim of the research is the hygienic assessment of soil contamination in the residential areas adjacent to TSFs. Material and methods. Atomic absorption spectrophotometry method was used for the determination of heavy metals. The study presents the results of analyses of 444 samples of gross content of lead, zinc, copper, mercury, arsenic, and cadmium in the soil of Khapcheranga, Sherlovaya Gora, Kadaya, Vershino-Darasunsky, and Vershino-Shakhtaminsky mining villages throughout the duration of 2012 - 2015. Results. During the period of the study the total value of soil contamination with Zc calculated by the median concentrations in Khapcheranga Village amounted to 4.7 6.9, in Vershino-Shakhtaminaky - to 6.7 8.8, which corresponds to the «allowable» level of the contamination. Zc calculation by maximum concentrations has shown the soil to be referred to the category from “moderately dangerous” to “extremely dangerous”; this value in Khapcheranga Village amounted to 48.7 - 235.3, in Vershino-Shakhtaminsky Village - to 23.76 - 164.8. Discussion. In the residential areas the allowable degree of soil contamination was determined to be predominantly observed; Khapcheranga and Vershino-Shakhtaminsky villages are the exceptions. The results of the assessment give the evidence of tge increased lead, cadmium and arsenic content throughout the entire area of the villages, while the highest levels of accumulated toxic substances are registered in the areas located near the TSF Conclusion. Thus, several zones of natural and anthropogenous contamination with increased concentrations of heavy metals and arsenic have been formed in the Trans-Baikal Territory. This dictates the need to study the influence of geochemical anomalies on the health of population.

Abstract: Saffron is one of the most expensive spices in the world, and its popularity as a tasty food additive is spreading rapidly through many cultures and cuisines. Minerals and heavy metals are minor components found in saffron, which play a key role in the identification of the geographical origin, quality control, and food traceability, while they also affect human health. The chemical elements in saffron are measured using various analytical methods, such as techniques based on spectrometry or spectroscopy, including atomic emission spectrometry, atomic absorption spectrometry, inductively coupled plasma optical emission spectrometry, and inductively coupled plasma mass spectrometry. The present study aimed to review the published articles about heavy metals and minerals in saffron across the world. To date, 64 chemical elements have been found in different types of saffron, which could be divided into three groups of macro-elements, trace elements, and heavy metals (trace elements with a lower gravity/greater than five times that of water and other inorganic sources). Furthermore, the chemical elements in the saffron samples of different countries have a wide range of concentrations. These differences may be affected by geographical condition such as physicochemical properties of the soil, weather and other environmental conditions like saffron cultivation and its genotype.

The aim of the study was to study the content of some heavy metals and arsenic in members of the Cricetidae family of hamsters and to develop centile scales for assessing the level of accumulation of these elements for the Central Federal District. In 2018–2020, hamster`s wool was studied for the accumulation of zinc, copper, iron, lead, cadmium and arsenic by the atomic absorption method. The data on the characteristics of the content of chemical elements in different sexes of animals are given. In the course of the study, it was found that, according to the value of the average content in the wool of animals of the family, the studied elements form the following decreasing series: Fe> Zn> Pb> Cu> Cd> As. When studying the features of the accumulation of chemical elements by different sexes, a significant increase in the concentration of zinc, iron, cadmium and arsenic in the wool of males was established, compared with females, depending on the species, from 1,38 to 3,98; from 1,28 to 1,52; from 2,00 to 304,00 times, respectively. With regard to the accumulation of copper in the body, the opposite trend is observed. In females, its concentration is 1,5–3,19 times higher. In the studied sample of animals, an increase in copper content was revealed in 44,83% of individuals and a decrease in cadmium in 44,82%.

Even if the Periodic Table of Chemical Elements is relatively well defined, some controversial terms are still in use. Indeed, the term “heavy metal” is a common term used for decades in the natural sciences, and even more in environmental sciences, particularly in studies of pollution impacts. As the use of the term appears to have increased, we highlight the relevance of the use of the term “Potentially Toxic Element(s)”, which needs more explicit endorsement, and we illustrate the chemical elements that need to be considered.
