“…The average content order of HMs in potatoes is as follows: Zn(1.883) > Cu(0.581) > Ni(0.28) > Cd(0.017) > Cr(0.058) > As(0.01) > Pb(0.04), which is significantly different from potatoes irrigated with acid mine drainage, characterized as: Pb(20.65) > Ni(14.56) > Cu(9.00) > Cd(4.35) [71]. The average content order of HMs in leeks is as follows: Zn(2.92) > Cu(1.212) > Cr(0.696) > Ni(0.47) > Pb(0.096) > As(0.038) > Cd(0.015); which is different from the same study within Slovakia, (Zn(2.32) > Cu(0.62) > Pb(0.283) > Ni(0.24) > Cr(0.192) > Cd(0.102)) [77], showing that the content of HMs in leeks is different under different background values. From the above four sets of data, it can be seen that the content of Cu and Zn were higher than other HMs and the content of Cu and Zn in wheat and corn is about 10 times higher than those in potatoes and leeks.…”

The purpose of this study is to evaluate the bio-accumulation of different soil-crop systems (SCSs) for heavy metals (HMs) and the geo-accumulation of different agricultural growing regions. The ecological risk (ER) assessment was conducted to understand the impact of intensive agricultural production on the environment. To achieve this aim, four typical crops, wheat, corn, potatoes, and leeks grown in the Jiao River Basin (JRB), were selected as the research objects. The concentrations of eight HMs, including copper (Cu), lead (Pb), zinc (Zn), nickel (Ni), chromium (Cr), cadmium (Cd), arsenic (As), and mercury (Hg) in crop tissue and soil were detected. The statistical analysis, including the geo-accumulation index (Igeo), geostatistical analysis, correlation and cluster analysis were then used to evaluate soil contamination and determine the source types of HMs. The results show that the average concentrations of eight HMs in the soil follow the order: Zn > Cr > Ni > Pb > Cu > As > Cd > Hg and the calculated concentration coefficients (K) vary from 0.41–1.12, indicating relative scarcity in sources of HMs. All the Igeo values of HMs are less than 0 except the Igeo of Cr within potato-farmland is from 0 to 1, illustrating that the soil in JRB is uncontaminated. The correlation and cluster analysis reveal that Cu, Zn, and Cd have a strong relationship with each other and the relationship between Pb, Ni, and Cr is general. The content of eight HMs in different crops varies greatly and most of them are within the scope of National Food Safety Standards—Limit of Pollutants in food of China. The bioconcentration factors (BCF) indicate that wheat, corn, potato, and leek have strong bio-accumulation ability of Cu, Zn, and Cd. The ecological risk factor (Er) shows that JRB is in low risk of Cu, Pb, Zn, Ni, Cr, and As; however, the risk of Cr and Hg are mostly low, characterized by partially dotted moderate risk. The risk index (RI) is mainly moderate with partially low risk distributed in planar and high risk distributed in point.

“…However, such interaction may be very difficult to study in a natural environment and must be evaluated in a controlled setting. Previous studies have already dealt with multi-element accumulation by plants [ 21 , 22 , 23 ]; however, they did not consider the effect of a poly-metallic growing medium on plant development [ 22 , 23 ] nor did they consider these relations in light of the mathematical formalism of DoE [ 21 ].…”

The Design of Experiment as a Tool to Model Plant Trace-Metal Bioindication Abilities

et al. 2022

Bioindicator plants are species that have the capacity to linearly uptake some elements (metal and metalloids) from the growing substrate, thus reflecting their concentration in the soil. Many factors can influence the uptake of these elements by plants, among which is the simultaneous presence of several metals, a common situation in contaminated or natural soils. A novel approach that can be used to validate the bioindication ability of a species growing on a polymetallic substrate is the design of experiment (DoE) approach. The aim of the present study was to apply the DoE in full factorial mode to model the Cu, Cd, Pb, Zn, and Cr bioindication capacity of Polygonum aviculare, used as the model plant. The results showed that P. aviculare has the ability to bioindicate Cd and Cr with a linear uptake (from 0.35 to 6.66, and 0.1 to 3.4 mg kg−1, respectively) unaffected by the presence of other metals. Conversely, the uptake of Pb, Cu, and Zn is strongly influenced by the presence of all the studied metals, making their concentration in the plant shoot not proportional to that of the soil. In conclusion, these preliminary results confirmed that the DoE can be used to predict the bioindicator abilities of a plant for several elements at the same time and to evaluate the interactions that can be established between variables in the growing medium and in the plant itself. However, more studies including other plant species are needed to confirm the effectiveness of this method.
