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.
