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\u22121, 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.<\/jats:p>","DOI":"10.3390\/molecules27061844","type":"journal-article","created":{"date-parts":[[2022,3,13]],"date-time":"2022-03-13T22:29:43Z","timestamp":1647210583000},"page":"1844","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Design of Experiment as a Tool to Model Plant Trace-Metal Bioindication Abilities"],"prefix":"10.3390","volume":"27","author":[{"given":"Mirko","family":"Salinitro","sequence":"first","affiliation":[{"name":"Department of Biological Geological and Environmental Sciences, University of Bologna, 40126 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0029-4403","authenticated-orcid":false,"given":"Alessandro","family":"Zappi","sequence":"additional","affiliation":[{"name":"Department of Chemistry \u201cG.
