Abstract

Heavy metal pollution, primarily driven by escalating human and industrial activities, poses a significant threat to ecosystems. Arsenic (As), a prominent toxic metalloid, is a major environmental contaminant with detrimental effects on plant health and crop productivity. In this study, the tolerance and toxic thresholds of sodium arsenate were assessed in four accessions of Hordeum vulgare (barley). A range of thirteen molar concentrations (10⁻¹³ M to 10⁻¹ M) of sodium arsenate was used to treat seven-day-old barley seedlings. Radicle length was measured as the primary parameter to determine arsenic toxicity and tolerance levels. Results indicate that 10⁻³ M concentration marks the threshold nearing toxicity, while lower concentrations allowed radicle growth, revealing varying degrees of tolerance among barley accessions. This study provides critical insights for arsenic phytotoxicity and offers a foundation for identifying tolerant barley varieties for cultivation in arsenic-affected regions.
