Phytoremediation potential of Brassica juncea L. grown in different Cd and Pb polluted sewage irrigated soils

Overview

This field study assessed cadmium and lead uptake and the phytoremediation potential of Brassica juncea across four sewage-irrigated sites in Prayagraj, India, computing bioaccumulation and translocation factors. It is upstream mechanism evidence on Cd/Pb soil-to-plant transfer under sewage irrigation; it reports no retail food occurrence and is context-only for Heavy Metal Index purposes.

Key numbers

• Plant-tissue Cd and Pb across sites ranged (roots and shoots) roughly 3.51-1.97 / 3.69-2.25 mg/kg for Cd and 4.78-3.11 / 5.13-3.06 mg/kg for Pb (values as printed, ± site SD).
• Maximum shoot accumulation was Pb 5.13 mg/kg followed by Cd 3.69 mg/kg at the Naini site.
• Bioaccumulation (BAF) and translocation (TF) factors were >1 for both metals across most sites, supporting B. juncea as a hyperaccumulator for phytoremediation of contaminated soils.

Methods (brief)

Soil and plant sampling at four sewage-irrigated sites; metals by digestion and instrumental analysis; phytoremediation potential expressed via BAF and TF.

Implications

Certification: Contributes nothing to HMT&C threshold pools. Mechanism evidence on Cd/Pb soil-to-plant transfer and phytoremediation; route as exposure/mechanism context to Soil-to-plant transfer of heavy metals, Cadmium, Lead, and Agronomic mitigation.

Courses: Field illustration of sewage-irrigation as an anthropogenic Cd/Pb input and Brassica juncea as a phytoremediation tool (BAF/TF > 1).

App: No contamination_profile blocks are touched.

Microbiome: Not a focus of this source.

Verification notes

• Evidence tier B: primary field-sampling study in a peer-reviewed journal.
• Page grounded in the published abstract plus the PDF first page (read on ingest for authorship); values preserved as printed. The abstract’s concatenated tissue ranges are reproduced as printed and should be re-checked against the source tables before any downstream numeric use.
• Authors resolved from the PDF (not indexed in Crossref/OpenAlex); raw file renamed from the discovery placeholder x2024-... to ojha2024-....
• ingredients: [] / products: [] correct: experimental phytoremediation context, not retail food occurrence; mustard is the test species, carried in matrices.
• Part 2 direction-of-edit check: adds upstream mechanism literature; neutral to HMT&C thresholds, moves toward the literature.
