Phytoremediation Potential of Native Plants Growing in Industrially Polluted Soils of Al-Qassim, Saudi Arabia

Rapid industrialization has resulted in the release and subsequent accumulation of heavy metals (HMs) various environmental matrices, which poses serious health threats globally. Utilizing native plant species to extract such HMs from soil may be an efficient cost-effective remediation approach. Thus, HM industrial area Al-Qassim province, Saudi Arabia, was investigated this study, phytoremediation potential assessed. Briefly, 30 surface samples 10 plants were collected different locations studied area. Soil analyzed for physiochemical characteristics contents, while digested concentrations determined. The results showed that Fe highest concentration (3900–19,600 mg kg−1), followed by Mn, Zn, Ni, Pb, Cr, Cu, Cd. Similarly, also higher (432 Mn (70.2 kg−1) Zn (38.1 kg−1). Enrichment factor revealed 90% extremely enriched with Cd, 20% highly Pb. contamination (5.0–46.9) Higher bioaccumulation (>1) Phrgmites australis Chenopodium marale Cd album, Lactuca serviola, Pulicaria crispa suggested these can effectively used soil.
