“…It is reported by Byrne et al [70] that HMs concentration negatively affects the diversity and abundance of species in an area. Similarly, soil metal concentration directly impacts species richness and the Shannon diversity index, impacting plant diversity [11]. The current results revealed that a community's species richness and Shannon diversity index decreases with increased HM contents and substantially correlates.…”

“…High concentrations of toxic metals, including Zn, Cu, and Cd are mostly due to human activities [8,9]. Metal contamination in the environment would affect the diversity, microbial properties, and functional diversity of soils [10,11]. Moreover, increased concentration of metal in the soils can be transferred and deposited into plants and likewise to human beings, producing numerous serious health disorders [6,12].…”

Heavy metals (HMs) are widely recognized for their toxicity and have serious environmental implications as technology advances and public pressure mounts to guarantee the safest and healthiest environment. This study evaluates the phytoremediation potential of HMs i.e., Copper (Cu), Zinc (Zn), Lead (Pb), and Cadmium (Cd) by Calotropis procera (Aiton) W.T. Aiton, also known as Sodom apple, along an urban–rural gradient and its effect on communities’ diversity, forage and medicinal quality in semi-arid region of Khyber Pakhtunkhwa Pakistan. The HM concentration was investigated along with the urban–rural gradients by sampling C. procera and soil samples. Acid-digested samples were tested for metal concentration using an atomic absorption spectrophotometer (AAS). We used principal component analysis and cluster analysis to identify the pattern of metal distribution in plants and soil. To comprehend the species’ diversity of plant communities in polluted sites, the species’ composition of C. procera communities was explored. Our results showed that the concentration of HMs in the soil and plant decreased from Zn to Cd (Zn > Cu > Pb > Cd). Likewise, more than half of the soil metal accumulated in the roots and aerial part of the plant, indicating the bioaccumulation potential of the plant species for these metals. Zn, Cu, Pb, and Cd translocation ratio varied from root > stem > leaf > flower. Root to stem transfer of metal was poor, but strongly mobilized to the leaves when available in the stems. Carthamus lanatus, Sonchus asper, Cynodon dactylon, Xanthium strumarium, and Silybum marianum were the leading species in three groups of 36 plant species. Pearson’s correlation revealed a significant relationship between HM concentrations and diversity indices. Zn and Cu content in the soil influenced plant species richness, Shannon–Wiener index (H′), and evenness index (Eh). Given the environmental toxicity of HMs, Cd concentrations in soil exceeded the permissible level, suggesting residents should be warned about potential health risks. As a result, the species chosen for this study can be employed as a biomonitor and phytoremediator of soil contaminated by these HMs, as it can accumulate HMs to a toxic level.

“…The increase of Cu content promoted the increase of the Shannon-Wiener and Simpson indices, which translated to a positive effect on the species diversity of the herbaceous community in Xinjian Dyke. Deng et al (2021) found that certain Cu concentrations were significantly positively correlated with plant height, stem thickness, crown diameter, and plot coverage (Deng et al, 2021), and therefore this metal may promote community species diversity. Séleck et al (2013) suggested that Cu may be a key factor in regulating plant community species diversity.…”

“…However, the effects of heavy metals on plant community species diversity are seldom reported. Most studies on plant population effects have focused on the community diversity of plants and microbes in aquatic environments and abandoned mines (Jia et al, 2019;Yang et al, 2020;Deng et al, 2021). Therefore, the present study assessed the effects of soil heavy metals on the community diversity of native hygrophytes in the Xinjian Dyke restoration and reconstruction area of Caizi Lake National Wetland Park, after which an optimal plant community species structure was proposed.…”

This study assessed the effects of heavy metals on plant community species diversity in the restoration and reconstruction area of Xinjian Dyke in Caizi Lake National Wetland Park. Using a positive matrix factorization (PMF) model, principal component analysis (PCA), regression, and correlation analysis, our study determined that the main sources of soil heavy metals in the study area were organic fertilizer, transportation and agricultural activities, and natural sources. Hg, Cd, Zn, As, Cr, and Cu were the main heavy metals in the study site. The Shannon-Wiener, Margalef, and Simpson indices were used to evaluate plant diversity. Our findings indicated that Hg was not significantly correlated with any of the three indices, Cr and As were positively correlated with the indices, and Cd and Zn were negatively correlated with the indices. Furthermore, Cu was positively correlated with the Shannon-Wiener and Simpson indices, and negatively correlated with the Margalef index. These findings indicated that the uniformity of the individual distribution among species was an important factor of community diversity, and the differences in the community diversity indices were related to the heavy metals in the soil. To improve the difference and functional complementarity between coexisting individuals, single superior species must be avoided and niche differentiation must be maintained as much as possible. Soil pH value, SOM, and other conditions should be improved to inhibit the migration and diffusion of heavy metals, improve their bioavailability, and give priority to local pioneer plants instead of functional redundant species.

Assessment of Heavy Metals Accumulation in Soil and Native Plants in an Industrial Environment, Saudi Arabia

et al. 2022

Industrial activities are associated with various heavy metals (HMs) being emitted into the environment, which may pose a threat to humans and animals. The rapid increase in an industrial activity in major cities in Saudi Arabia (SA) has raised concerns regarding the accumulation of HMs in the environment. The aim of this study is to assess the accumulation of HMs in soil and native plants in an industrial environment. We collected 36 surface soil samples and 12 plant species from 12 sites in an industrial city in central SA. The results showed that the HMs content in the soil followed a descending order of (Fe > Ni > Zn > Pb > Cu> Cr > Cd). The enrichment factor (EF) of HMs in the soil ranged from 0.20 to 7336. Up to 100%, 16.6%, and 6.2% of soil samples were extremely highly enriched with Cd, Ni, and Pb, respectively. Plant species Cyperus laevigatus accumulate Cd, Pb, and Ni. Citrullus colocynthis accumulate Cd and Pb in significantly (p < 0.001) higher amounts than other studied species. The Pollution Load Index (PLI) values for the 12 sites ranged from 0.52–1.33 with S5 and S2 PLI >1.0 indicating progressive deterioration of these sites. The Bioaccumulation Factor (BF) ranged from 0.04–2.76 and revealed that some plant species may be candidates for phytoextraction potential. The most promising plant species for phytoextraction and remediation were annuals or perennials such as Malva parviflora, Sisymbrium irio and Citrullus colocynthis, especially for Cr and Cu. This study suggests that these native plant species may be useful for phytoremediation in the area.
