Tantri 2026 — Cadmium contamination of agricultural soils and food security in Indonesia

This integrative study synthesizes secondary data on cadmium in agricultural soils of West Java and Central Java, computing contamination and ecological-risk indices and relating soil Cd to food-security risk. It is upstream soil-burden and exposure context for cadmium; it reports no primary retail food occurrence and is context-only for Heavy Metal Index purposes. It is exactly the kind of soil-contamination-assessment evidence the routing layer connects to crops grown on affected ground.

Key numbers

• Standardized soil Cd concentrations (mg/kg dry weight, from AAS and ICP-OES) synthesized for 2022-2024; Contamination Factor (CF) and Ecological Risk factor (Er) computed via the Hakanson (1980) model.
• Bandung Regency (West Java): highest soil Cd at 6.6 mg/kg with extreme ecological risk (Er = 990), linked to textile and electroplating industry and wastewater discharge.
• Brebes-Demak-Pati (Central Java): moderate-to-high contamination at 2.2 mg/kg (Er = 330), attributed to prolonged fertilizer and pesticide use.
• Despite soil contamination, Cd in rice from Semarang was reported below the detection limit — a soil-burden-does-not-equal-food-concentration illustration.

Methods (brief)

Quantitative descriptive-comparative synthesis of secondary data from indexed scientific publications and Statistics Indonesia (BPS); CF and Er indices and correlation analysis between soil Cd and the percentage of polluted villages.

Implications

Certification: Contributes nothing to HMT&C threshold pools (no primary food occurrence). Upstream soil-burden/exposure context for cadmium in an important growing region; route as exposure/regulatory context to Soil-to-plant transfer of heavy metals and Cadmium.

Courses: A clean teaching case that high soil Cd (and ecological risk) need not translate into elevated grain Cd (Semarang rice below detection), reinforcing the soil-is-not-food rule.

App: No contamination_profile blocks are touched.

Microbiome: Not a focus of this source.

Verification notes

• Evidence tier C: secondary-data descriptive synthesis, not primary measurement; regional soil values are reproduced from cited sources and should be re-verified before any downstream use.
• Page grounded in the published abstract and bibliographic metadata; values preserved as printed.
• metals: [Cd]; ingredients: [] / products: [] correct — soil/exposure context, not retail food occurrence.
• This source is a concrete example of the literature the discovery filter previously excluded (“soil contamination assessment”); the 2026-06-18 scope fix restores its inclusion.
• Part 2 direction-of-edit check: adds upstream exposure context; neutral to HMT&C thresholds, moves toward the literature.
