文摘

•: ⁸⁷Sr/⁸⁶Sr ratios and REEs patterns of Indian Basmati rice samples were evaluated for geographical tracer.
•: Uttar Pradesh originated rice found comparatively more radiogenic for ⁸⁷Sr/⁸⁶Sr.
•: Indian Basmati rice showed significant different ⁸⁷Sr/⁸⁶Sr ratios than other regions.
•: Strong correlation observed between ⁸⁷Sr/⁸⁶Sr of rice, silicates, carbonates and irrigation water.
•: Water seems to be the possible source of Sr in rice plant.
