“…Any decrease in microbial diversity or abundance may adversely affect nutrient absorption from the soil by plants. In addition, heavy metals can also be absorbed by plants and negatively affect human health after consumption (Kalaivanan and Ganeshamurthy, 2016; Glavač et al., 2017; Ibrahim and Selim, 2018; Magaji et al., 2018). In fact, heavy metals are not easily biodegradable and consequently can be accumulated in human vital organs.…”

The increase in agricultural production as well as its nutritional quality at a cost bearable by producers is today a challenge in rural areas. Vermicompost is a low-cost organic amendment known for its effectiveness on agricultural productivity increase but little is diffused about its efficacy on nutritional quality. This study aimed to evaluate the benefits of vermicompost from cattle dung on Lagenaria siceraria yield and its edible parts content in mineral and in heavy metal compared to raw dung. The study was carried out in the region of Mankono the biggest area for L. siceraria production in Côte d’Ivoire during three cycle seasons. The experiment consisted of three treatments arranged in a complete randomized block design with four replicates. The agronomic parameters as yield, number of leaves and flowers per plant were evaluated. Also, mineral nutrients and heavy metal concentrations in roots, leaves and seeds were measured. Results showed that yield, number of leaves and flowers per plant were higher with the vermicompost than with the cattle manure and the control. The yield obtained with the vermicompost was 2.5 times and 20 times higher respectively than that with the cattle manure and the control. Mineral concentrations in roots, leaves and seeds were the highest with the vermicompost when heavy metal contents were the lowest. The present study indicates that vermicompost utilization improves the yield and the nutritional quality of the edible parts of L. siceraria and hence could be recommended to producers for increasing productivity with keeping the health and safety of human.

“…Полученные данные о содержании свинца в ЛРП хорошо согласуются с данными отечественных и зарубежных исследователей [10][11][12][13][14][15][16], что свидетельствует об отсутствии существенных различий в контаминации свинцом дикорастущих и выращиваемых растений. Следует отметить, что содержание свинца в растениях очень чувствительно к влиянию антропогенного фактора [17,18], так, например, повышенное содержание свинца в ЛРП наблюдается в местах разработки свинцовых руд и в районе расположения металлообрабатывающих предприятий [19,20], отмечено увеличение содержания свинца (до 25 мг/кг) в образцах ЛРС из Кемеровской области [4].…”

The inclusion of requirements for independent determination of arsenic, cadmium, mercury, and lead, and the current sample preparation techniques into the State Pharmacopoeia of the Russian Federation (Ph. Rus.) requires the revision of the existing limits for elemental toxicants in herbal substances and herbal medicinal products produced from them.The aim of the study was to analyse the data on elemental toxicant content obtained during quality control of herbal substances (herbs, medicinal herb mixtures, extracts, and tinctures) using current test methods and sample preparation techniques, and to compare the obtained results with the Russian and foreign scientific and specialist literature.Materials and methods: the internal data on the content of critical heavy metals and arsenic in different dosage forms of herbal medicinal products, which were obtained by inductively coupled plasma mass spectrometry after sample preparation by decomposition in closed vessels, were compared with literature data. Results: it was demonstrated that the content of lead, cadmium, and mercury in all the test samples did not exceed the Ph. Rus. limits and was consistent with the analysed literature. The arsenic content in some herbal medicinal products was higher than the established Ph. Rus. limits, but complied with the less stringent Ph. Eur. and USP requirements for herbal substances. The authors investigated the link between the content of elemental toxicants and the place of collection and the part of the plant being tested. It was shown that different types of medicinal plants had a tendency to accumulate particular elements. The authors determined the content of the elements to be controlled in extracts and tinctures. The differences in the Russian and foreign requirements for the content of elemental toxicants may be attributed to the method of obtaining experimental data that form the basis for the setting of limits.Conclusions: the results of the study confirm the validity of the existing limits for elemental toxicants in herbal medicinal products. The authors demonstrated the need to revise the existing limits for arsenic in herbal medicinal products.

The selection of plant species at mine sites is mostly based on metal content in plant parts. Recent works have proposed referring to certain ecological aspects. However, plant traits for plant metal-tolerance still need to be accurately assessed in the field. An abandoned Zn-Pb mine site in Gard (France) offered the opportunity to test a set of ecological criteria. The diversity of micro-habitats was first recorded through floristic relevés and selected categorical and measured plant traits were compared for plant species selection. The floristic composition of the study site consisted in 61 plant species from 31 plant families. This approach enabled us to focus on seven wild plant species naturally growing at the mining site. Their ability to form root symbioses was then observed with a view to phytostabilization management. Four species were considered for phytoextraction: Noccaea caerulescens (J. et C. Presl) FK Meyer, Biscutella laevigata L., Armeria arenaria (Pers.) Schult. and Plantago lanceolata L. The metal content of their aerial and root parts was then determined and compared with that of soil samples collected at the same site. This general approach may lead to the development of a knowledge base for assessment of the ecological restoration trajectory of the site and can help in plant selection for remediation of other metal-rich soils in the Mediterranean area based not only on metal removal but on ecological restoration principles.
