This pot study grew several mung bean genotypes in soil spiked with arsenic and compared three soil amendments meant to relieve stress: biochar, arbuscular mycorrhizal fungi and selenium. The amendments raised catalase activity and lowered proline, which the authors read as reduced oxidative stress, with mycorrhizal fungi the most effective. Selenium content of the plants was not measured.
Key numbers
- Selenium was applied to soil at 15 mg/kg under an arsenic dose of 30 mg/kg (Methods).
- This paper reports no numerical findings relevant to selenium exposure.
Methods (brief)
Pot experiment with six treatments including an untreated control; leaf chlorophyll, catalase and proline were measured and compared by analysis of variance across genotypes.
Evidence fitness
Context only. It does not support statements about selenium in food, dietary exposure or toxicity, and it did not measure arsenic or selenium in edible seeds.
Limitations
Pot conditions; physiological markers only; selenium form and uptake not reported.
