“…Other studies showed that Mn is a competitor for Cd using the same mechanism for transfer in plant [33]. In the case of Fe, the concentrations extracted from the mustard plants did not indicated bioaccumulation in any of the polluted and control tests ( Figure 11).…”

“…In the processes of germination and development of plants subjected to the stress of metal pollution, mechanisms of self-defense/resistance/adaptation of the plant to the metallic elements are activated. The presence of anti-stress factors, respectively high content of Ca, Zn and Mg, microelements necessary for the growth/development and the functioning of photosynthesis processes allowed the development of plants even in conditions of exceeding the value of the intervention threshold for sensitive uses in soil for Cd [33].…”

“…The total Cu concentrations in plants are in the normal concentration range, the values being between 8.61 ÷ 9.42 mg/kg, but below the value of the control test (15.3 mg/kg) and much below the phytotoxic value of 20 mg/kg [27]. The studies showed that Cd could reduce or increase the Cu uptake in plants organs [33]. In M3 test, after 60 days, transfer factors were lower than M2, indicating a reduced ratio of Cu mobility in mustard plants inversely proportional to the Cd concentration.…”

Heavy metal toxicity in plants is well known due to their severe phytotoxic effects and also because of their capability to accumulate in vegetables. The use of aromatic plants in remediation techniques has increased in the context of environmental pollution issues, including metal soil contamination. Cadmium is knowed as a toxic and bio accumulative element provided by natural or anthropic sources. In this context, the paper presents a laboratory experimental study aiming to evaluate the accumulating and transfer behavior of Cd in the plant organs of Sinapis alba L. (white mustard) and in the presence of essential elements (Ca, Mg, Fe, Zn, Mn, Cu, Ni). The study involves a comparison between white mustard cultivated in unpolluted soil and in two Cd polluted soils at values above the alert (2.8 mg/Kg), respectively intervention threshold for soils with sensitive use (5.6 mg/kg) according to the legislation in force in Romania. While Cd accumulated predominantly in roots (TC values 1.46 and 2.22), its transfer to the stem and leaves was observed too, the TF values for the aerial part of the plant being greater than 1. Moreover, the study showed that certain elements (Zn, Ca, Mg, Mn) were found in higher concentrations in plants subjected to Cd pollution than in the control sample indicating antagonistic effects and Cd toxicity limiting. Other essential metals, such as Cu, Fe and Ni were found in lower concentrations in intoxicated plants compared to control plants. Their translocation from soil in plant organs could be reduced by the Cd toxicity. Contrariwise, the mobility of these elements from roots to leaves could support the tolerance effect of plants to Cd stress. The study allows us to consider that Sinapis alba L. aromatic plants are suitable for soil phytoremediation technologies used in Cd decontamination.

“…One of the features of H perforatum attracting scientists' atten tion is its ability to concentrate cadmium (Lovkova & Buzuk 2013, Jurca et al 2011. Cadmium affects plant growth and development due to its toxic effects (Hussain et al 2015, Rizwan et al 2016, Farooq et al 2019, Qin et al 2020 even at low concentrations (White & Brown 2010, Dias et al 2013.

Medicinal plants can amass chemical elements in their tissues due to their ability to tolerate potentially toxic ions in the environment. The Hypericum perforatum L. plants were cultivated in three regions of West Siberia (Kemerovo, Novosibirsk, Kam lak Village (Altai Republic)). Elemental analysis was conducted by atomic emission spectrometry. Chemical elements extractable with 10% HCl were assayed by atomic absorption spectrometry. The concentrations of Co, Ni, Cu and Zn have been relatively stable. The coefficients of biogeochemical mobility of Cd, Cu and Zn had high rates, which confirm the possibility of accumulation of these elements in H. perforatum. The concentration of chemical elements in extracts (10 % HCl) was increased as well as their total contents, the degree of extraction was highest for K, Ni, Fe, Cu, Mn, Mg (90 % or more), the minimum for Na (20–40 %) and significantly changed in environmentally different habitats.

“…One of the harmful waste is Cadmium (Cd) (Zhang et al, 2015). Cadmium is a heavy metal with atomic number 48 and includes transition metals, harmful to humans, animals, microorganisms, and easily absorbed by plants (Qin et al, 2020). In agricultural land, Cd can come from various industrial wastes, mining, household waste, the use of excess pesticides and fertilizers, especially phosphate fertilizers (María et al, 2020).…”

Cadmium (Cd) is a harmful metal for paddy soil that is affected by inorganic fertilizer, pesticides, and industrialization. This study aimed to investigate the Cd contents in paddy soil, plant tissue, and grain, as well as the spatial distribution of potential Cd contamination. This study was conducted in Sragen Regency on paddy fields with different management, i.e., organic paddy fields, conventional paddy fields (Alfisols, Entisols, Inceptisols, and Vertisols), and paddy fields that often use wastewater (textiles, batik, and sugar factories) for irrigation. Forest land was used as a control. This study used descriptive explorative methods based on overlay land use, soil type, and industrial distribution map of Sragen Regency. The results showed that paddy soils with different management had higher Cd content than the forest soil. Organic paddy field had the lowest Cd content in soil (0.019 ppm) and rice grain (0.0006 ppm). Approximately 1,914.4 ha (3%) of paddy field in Sragen Regency that uses sugarcane industry wastewater as irrigation had the highest soil Cd content (0.16 ppm). In contrast, the highest Cd content in rice grain (0.046 ppm) was observed in conventional paddy field. The management of paddy field and rice cultivation significantly affected Cd contamination in soil and rice grain; therefore, environmentally friendly paddy field management needs to be encouraged.
