Samitha et al. 2021 - Monitoring Heavy Metal Contamination in the Pineapple (Ananas comosus) Cultivated tracts of Kerala, India
This study measured Pb, Ni, Cd, and Fe in pineapple cultivated soil, reference soil, roots, leaves, and fruits from Kerala, India.
Key numbers
Source units are mg/kg.
- Pineapple fruit: Pb below detectable limit; Ni 3; Cd 4; Fe 145.6.
- Pineapple roots: Pb 8; Ni 6; Cd 20.5; Fe 204.
- Pineapple leaves: Pb 2; Ni 4.4; Cd 13.8; Fe 184.97.
- Cultivated soil: Pb 39.73; Ni 10.42; Cd 62.33; Fe 25168.
- Reference soil: Pb 4; Ni 1.26; Cd 10; Fe 11356.
- Fruit bioconcentration factors reported in the abstract: Pb 0, Ni 0.2879, Cd 0.0641.
Methods
The study estimated Pb, Ni, Cd, and Fe using atomic absorption spectrophotometry and calculated transfer, enrichment, contamination, and geoaccumulation indices.
Implications
The fruit values are routeable for pineapple ingredient context, while root, leaf, and soil values are context-only for plant uptake and field contamination.

Verification notes
- Source identity checked against DOI 10.47191/ijcsrr/V4-i5-14 and the downloaded PDF.
- The PDF text reports high soil Cd; fruit Cd is separately reported as 4 mg/kg and should not be pooled with soil values.
