Ojha et al. 2024 — Phytoremediation potential of Brassica juncea on sewage-irrigated Cd/Pb soils

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.
